DNS server returns IP addresses even for domain na...

Like a number of other people I have been looking at the BT Broadband service and have found that there is an issue with the current DNS server. What I / we have found is that the DNS server returns IP addresses even for domain names which should not resolve. See following -
DNS results wildcarding (?): Warning
Your ISP's DNS server returns IP addresses even for domain names which should not resolve. Instead of an error, the DNS server returns an address of 92.242.132.15, which resolves to unallocated.barefruit.co.uk.
There are several possible explanations for this behavior. The most likely cause is that the ISP is attempting to profit from customer's typos by presenting advertisements in response to bad requests, but it could also be due to an error or misconfiguration in the DNS server.
The big problem with this behavior is that it can potentially break any network application which relies on DNS properly returning an error when a name does not exist.
The following lists your DNS server's behavior in more detail.
www.{random}.com is mapped to 92.242.132.15.
www.{random}.org is mapped to 92.242.132.15.
fubar.{random}.com is mapped to 92.242.132.15.
www.yahoo.cmo [sic] is mapped to 92.242.132.15.
nxdomain.{random}.netalyzr.icsi.berkeley.edu is mapped to 92.242.132.15.
Moderators could you please investigate this for us.

BT use a Barefruit (which your post seems to suggest) service called 'Error Resolution'.
http://www.barefruit.com/background/error_resolution.php
Any DNS that can not get resolved goes via this service and returns a page showing paid adverts and/or links related to what they think you were looking for.
BT refer to this as 'BT Web Address Help' and can be turned off on an opt-out basis via this link: http://preferences.webaddresshelp.bt.com/selfcare/
I assume BT's view is this helps improve the user experience and provides some directed help instead of a blank error page.

How to use DNS server for name resolution for items which don't exist in active directory domain controller DNS

Dear Experts,
In our office we have a domain controller call it 'Office.com', all computers and corporate servers e.g. exchange, antivirus etc. are member of this 'office.com', it is also having a DNS. All users in office have there preferred DNS set to the corporate
DNS
We are working for ministry and offering services to them from our data center so have many servers which are for ministry but they are in our data center. For all these servers we created another DNS server which contains all entries for these servers in
forward and reverse lookup zones. In this DNS we also created a forward lookup zone for our corporate servers and zone name is 'office.com'
What we are trying to have is name resolution of all servers which are listed in other DNS build in our office on Win 2008 R2 for ministry servers
If the user change his preferred DNS to ministry DNS he can resolve the ministry server but then we can not control any thing through group policy since they are using other DNS and not the corporate DNS.
How this can be done ? like any group policy applied to corporate domain controller must take effect on users and in addition to this user must also be able to resolve server names in ministry project DNS
Please assist ASAP.
regards,

Hello,
ok so the GPO setting doesn't apply in any case.
Clients machines use the first DNS server in the list of configured ones on the NIC. If that one is available search for additional DNS servers will stop.
What i can not really understand is your description about the second DNS server. This should normally either another DC with AD integrated DNS, so everything is replicatedwithin AD replication or you use a secondary DNS on domain member server that pulls
the informations from the Master.
It sounds for me that you have configured a machine with DNS server role and created manually the zone with the same name as the domainand manually create there the required A records?

Edge Transport Server Fails DNS Query When Emailing to one Specific Domain

This issue occurs for the same domain across three different edge transport servers.
All servers are Windows 2008 STD SP2, Exchange 2007 SP1 U9. Emails are delivered using DNS connector from edge. Emails to this one specific domain would sit in the retry queue with DNS query error until NDR was generated. Connectivity Logging generated the following:
2009-09-01T19:52:23.539Z,08CBEDE9198E2DC3,SMTP,subdomain.domain.com,>,DNS server returned ErrorRetry reported by 208.241.124.200
2009-09-01T19:52:23.539Z,08CBEDE9198E2DC3,SMTP,subdomain.domain.com,-,The DNS query for 'DnsConnectorDelivery':'subdomain.domain.com':'cd771f71-77a3-4aca-b002-86f477816910' failed with error: ErrorRetry
I changed the servers DNS settings to different servers with the same response. Validated that manual MX lookups worked, and that I could telnet to any of the three MX records and deliver mail via telnet.
I did a packet capture and received the following:
12 32.280037 172.28.16.55 208.241.124.200 DNS Standard query AAAA SMTPSERVER.subdomain.domain.com
So what is happening is the Edge servers are only performing IP6 lookups, and throughout the log, only for subdomain.domain.com do they NOT perform a regular IP4 A record lookup. I then went about disabling TCP/IP6 as per this article:
http://technet.microsoft.com/en-us/network/cc987595.aspx
this stated to do the following:
Alternately, from the Windows XP or Windows Server 2003 desktop, click Start , point to Programs , point to Accessories , and then click Command Prompt . At the command prompt, type netsh interface ipv6 uninstall .
To remove the IPv6 protocol for Windows XP with no service packs installed, do the following:
Log on to the computer with a user account that has local administrator privileges.
From the Windows XP desktop, click Start , point to Programs , point to Accessories , and then click Command Prompt .
At the command prompt, type ipv6 uninstall .
Unlike Windows XP and Windows Server 2003, IPv6 in Windows Vista and Windows Server 2008 cannot be uninstalled. However, you can disable IPv6 in Windows Vista and Windows Server 2008 by doing one of the following:
In the Network Connections folder, obtain properties on all of your connections and adapters and clear the check box next to the Internet Protocol version 6 (TCP/IPv6) component in the list under This connection uses the following items .
This method disables IPv6 on your LAN interfaces and connections, but does not disable IPv6 on tunnel interfaces or the IPv6 loopback interface.
Add the following registry value (DWORD type) set to 0xFF:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents
This method disables IPv6 on all your LAN interfaces, connections, and tunnel interfaces but does not disable the IPv6 loopback interface. You must restart the computer for this registry value to take effect.
I did the above, and still, the Edge Transport servers would only perform AAAA lookups, and messages would sit in the queue.
As temporary workaround, created new send connector with the three available MX hosts as possible smarthosts for subdomain.domain.com, and this allowed email flow.
I've tried disabling the TCPIP6, and still doesnt work. Any suggestions?

Hi Allen and Paul,
we experience problems in receiving mails from senders with this Exchage server problem. When we are aware of the problem, we send them the above mentioned link and ask them to make adjustments. Then afterwards usually mail arrives without any problems.
The problem for us is that it seems as if the problem grows. More and more mail does not arrive on our mailadresses (mine for example is [email protected]) And not all of the senders recieve notifications that mail cannot be delivered. As you can imagine
this situation is unacceptable and damaging our customer relations.
Is there anything WE can do? (apart from sending them the information to make adjustements in their Exchange servers...)
I hope you can help us...
Thanks in advance
Leonard
Hi Leonard,
as stated below we where experiencing the same problem with one of our customers. Seeing that it's a DNS related problem we suggested to the customer to change or add an additional DNS service through i.e. dyndns.com. After adding the current DNS records
to the new DNS service mail started coming in from every customer that had problems.
So for your clients i would suggest a similar solution, it helped over here at least.
Kind regards,
Philipp

What is the trick in adding a "secondary zone" to my DNS server

Hello,
I am having a hard time adding a secondary zone to my dns server. I followed the instructions carefully but I still get the "refuse" on my zone transfer. Do I need to go to the "NIC" of my interface card and make the primary DNS
as the server itself and the secondary DNS the IP of the "remote" DNS server?
Also, do I need to start configuring the "reverse Lookup zone" (before even starting to add a "secondary zone" and perform a -ZONE -TRANSFER), and add first the "a" record of the other (remote) DNS server?
Thanks,
Teapaq Long.

Hi,
According to the event ID 6525, this may be caused by a refuse of zone transfer request.
In normal, the secondary DNS server just configured with a preferred DNS server as itself, the alternate DNS server is optional, it depends on your needs.
When you fill the master DNS server’s IP address when you add secondary zone in the secondary DNS server, it will prompt a warming information if you do not add a PTR record in the master DNS server in the reverse lookup zone, but this won’t affect the zone
transfer process.
Have you followed the description of event log and check to see if the master server has enabled zone transfer(Properties
of zone->Zone Transfer tab->Allow zone transfer)?
Besides, verify that the master server of the secondary zone is authoritative for the zone. Reference steps below:
1. On the secondary DNS server, open DNS manager.
2. Right-click zone, select the General tab, note the IP address of the server that is listed in
Master Servers.
3. In the console tree, right-click DNS, and then click
Connect to DNS Server.
4. Click The following computer, type the IP address of the master DNS server, and then click
OK.
5. In the console tree, expand the master DNS server, and then expand the folder that contains the zone.
Note: If the zone is not in the folder, the server is not authoritative for the zone. In this case, you must configure the secondary server to transfer the zone from the correct master server.
6. Right-click the zone, click Properties, and then click the
Name Servers tab.
7. Confirm that the secondary server is listed with the correct IP address. To correct the list, do one of the following:
If the secondary server is not in the list, click Add.
If the IP address of the secondary server is incorrect, click the server in the list, and then click
Edit.
If this problem still exits, from the event log I notice that there are 2 secondary DNS server, REM-LAB-2K3.leftremote.com and LOC-LAB-2K8.localright.com. Are they belong to different domain(leftremote.com and localrght.com) ? what the relationship between
them?
It would be helpful if you could provide the network topology. And describe the IP configuration of master DNS server and secondary DNS server.

Eve Wang

DNS server configuration and behaivour

Hi all,
I'm looking for detail explanations which can explain how Mac OS X 10.6 *DNS client* works and may be configured.
According to http://discussions.apple.com/thread.jspa?threadID=2227251 nothing is not guaranteed like order and failover.
According to http://support.apple.com/kb/HT4030 failover will take affect when DNS server returns with SERV_FAIL (0x2) error code. What about NXDOMAIN (0x3) error code (which is more interesting scenario)?
What I'm looking for DNS client?
I'm looking for several DNS servers configuration which allow to split DNS domains for several areas. This, for example, may be very useful for VPN connections when VPN DNS server will resolve internal resource and another server (configured before VPN tunnel established) will resolve external resources.
Is there any possible configuration to achieve this requirement for Mac OS?
Thanks in advance,
Oleg.

Thanks Felix for quick response.
In your scenario:
1. You configured to different DNS servers and probably only one of them replied to DNS queries. And this is OK.
2. When non valid IP configured means that DNS server will not reply to DNS query and than failover will query the second DNS server in the list. And this is also OK.
I'm looking 2 different DNS servers configuration when one of them will reply to different domains. For example:
First server will reply to *.mycompany.com.
The second one will reply to any query except mycompany.com domain(since it is not published).
Thanks again,
Oleg.

DNS server unknown

I am trying to get wireless connection to my Toshiba Satellite C655-S5132. However, the company router for NetGear is not allowing me to connect to the internet. The CD that came with the router, is irritating. It needs the IP Address, the IP Mask, the Gateway Server and the DNS, however, when I pull up the configuration for these things, it comes up as
DNS server:Unknown
IP Address:192.168.1.1
Also, when I pull up the System Information, everything: the gateway server, DNS, IP Address, the IP Mask, all have unavailable beside them.
If anyone can give me so help on this, I would be appreciative. I have racked my brain for two days on this router and the other one, a linksys.
Also, I can get the linksys to connect to the computer, but not to the internet.

This is one of those topics that is well beyond this forum but let me try. Beyond the router, you also need an ISP (Internet Service Provider) like AT&T, Cox, or the local phone company. The ISP provides a cable modem which then connects to the router. The router then connects either with a wire or wirelessly to the computers that are trying to connect to the Internet. Just having a router won't get your computer to the Internet. You need the ISP to provide the Public IP address, the DNS Server and the gateway to the Internet. DNS stands for Domain Name Services and it is what converts a website like Yahoo.com into an IP address like 123.5.173.9. From your questions and the nature of the problems you're having, I would suspect that you don't have an ISP or that the router is not connected correctly to the cable modem.

Cisco IOS as DNS server

Dear Community!
Could someone help me to fine-tuning DNS server configuration?
I'm configuring an IOS router act as a DNS server with the following parameters:
ip name-server [IP #1] [IP #2]
ip dns server
ip domain round-robin
ip domain name [domain.net]
The 1st DNS server is a public DNS server accessible from Internet, the 2nd one is a private corporate DNS server accessible from a site-2-site tunnel.
The client PCs at the remote end of the IPSec tunnel should query public DNS names from public DNS server, and the records of our private DNS domain.
Is it possible to configure a "policy" to query corporate DNS domain from a dedicated DNS server, and the other public DNS name from the public one?
Thanks in advance!

Sure, it's called DNS Proxy. It's not supported on all devices, so you'll have to check.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123relnt/800/rn830xc3.htm
DNS Proxy
In virtual private network (VPN), Point-to-Point Protocol over Ethernet (PPPOE), etc. PCs connected to the LAN may get Dynamic Host Configuration Protocol (DHCP) parameters including the IP addresses of the Domain Name System (DNS) server prior to the router connecting to the WAN to get the information over IP Control Protocol (IPCP). The objective with Proxy DNS (or caching-only name server) enables the router to receive DNS queries on behalf of the real DNS servers and proxy for the hosts on the LAN connected users. This enables the DHCP server to immediately send the hosts the router's own LAN address in lieu of the DNS server's IP address. The router forwards the DNS queries from local users to real DNS servers after the WAN connection comes up and caches the DNS records in response. Over the time, cache includes the DNS information most often requested by the local resolvers and this can reduce the overhead of packets to the WAN.
The router must obtain the correct DNS server information from the WAN in order for it to function as a proxy DNS server.
The global configuration command ip dns server enables DNS proxy server functionality on the router, and causes it to forward DNS queries to the actual DNS servers. The global configuration command dns-server address causes the router to respond to DNS queries with its own IP address.
HTH and please rate.

ISP won't let me use my configured DNS server-what to do?

I put Open DNS servers in my Mac OS X Network Preferences (OS X 10.6) for when I use DHCP connections. This works fine on one network (DHCP to a wireless router connected to internet via DSL), but when I connect to another network, I find that I end up using the network's DNS servers - It appears my computer is sending a request out for the Open DNS IPs (208.67.222.222 or 208.67.220.220) according to Little Snitch's network monitoring, but the ISP seems to be internally changing it to their own DNS server within their network before the domain name is looked up. I can verify whether Open DNS is really used by visiting welcome.opendns.com/ or by going to the mispelled craigslist.og (which Open DNS redirects to the classified ads). The troublesome situation is when I connect by wifi DHCP to my TMobile cell phone.
What can I do about these sorts of ISPs? Is there anything I can do?
Also, is there a page I can visit to tell me the IP address of the actual DNS server used, not just what I configured in my Mac?
Thanks

SCCM 2012 R2 update from 2012 in VM on SDC and secodary DNS server

Hi there,
I'm currently running SCCM2012 (not R2) on a secondary domain controller and secondary DNS Server. Bought a license for this in 2013. Would like better separation from above functions and deploy R2 version. Two questions:
1) Is it recommended to install SCCM R2 in a VM on a machine running above applications?
2) Do I need a new license to go from SCCM 2012 to SCCM 2012 R2?
Thank you for an answer, Marcel

Actually, for #2, that's not true. ConfigMgr 2012 and ConfigMgr 2012 R2 are separate SKUs and require their own licensing. Just because you have ConfigMgr 2012 does not entitle you to 2012 R2. It depends upon how you licensed it in the first place. If
you have Software Assurance (SA), then yes, your current licensing applies. You should check with your LAR or call the Microsoft licensing helpdesk to figure out if you are licensed for R2.

DNS Issues, can't set static DNS server

I have an Airport Extreme (which I'll call the router). It has an IPv6 tunnel (to Hurricane Electric), so it hands out IPv4 DHCP and announces an IPv6 network as well. The DNS servers configured on the router are OpenDNS'.
My Apple TV 2 is connected via wired Ethernet to the router. It was using a DHCP address provided by the router, which made the DNS server the same address as the router. I wanted to manually set the DNS to use my ISP's, so that I can make sure the Netflix streaming issue I have is not a DNS issue.
So I changed the Apple TV to a manual address, and set the DNS server to my ISP's DNS server (Apple TV can only have one DNS server? Odd.)
After I save this, the Network page shows the correct manual IP, mask, and router, but the DNS Address is an IPv6 address (one that belongs to my network, but the entire address isn't visible), not the one I set. When I Configure TCP/IP again, and I reach the DNS Address page, the first digit of the existing address is "20", and the rest of the digits are "0". Interesting note as well: if I press Down, the number will increment to 19, and so on, but if I press Up, it changes to 0. Obviously the UI isn't designed for IPv6 addressing, but there's an IPv6 address in there nevertheless.
Screenshots:
http://www.flickr.com/photos/random_robin/5310011344/
http://www.flickr.com/photos/random_robin/5310016288/
I have tried to set the DNS Address multiple times now, and have restarted the Apple TV. The IPv6 DNS Address persists.

After 16 hours of working i don´t have seen this easy solution. I had tried with Internet Explorer and Opera but finaly i have need to use Firefox.
Thanks a lot to solve it.

Cisco 1821 as DNS server

Hello I have a cisco 1821 router acting as remote access for vpnclients, LAN LAN VPN device and also
LAN router. All in one.
My LAN has a 192.168.23.0/24 addressing, and router has 2 IP Addresses, one on public IP on the public interface Fa0/1
and 192.168.203.1 on the private interface Fa0/0
I set up it as a name server for local LAN:
ip dns server
ip host pc10 192.168.203.10
ip host pc83 192.168.203.83
ip host c1821 192.168.203.1
I did this so that local PC on my lan can have a resolution for local addresses since I do not have a DNS server inside my line
and I do not have a Active Directory infrastructure.
on the public IP interface my router can be queried for LOCAL IP resolution for my lan 192.168.203.0/24, I Tryed from outside using dig command.
I Wanted to prevent this. I cannot use an ACL because I would prevent DNS queries to work in general. trying to resolve
an external IP Address from inside my lan, I just want the router to refuse DNS resolution for any query coming to external interface,
while I Want to allow only queries coming form my local lan to internal interface.
is this possible in some way ?
thank you
Riccardo

You are asking your IOS device to act as a split-DNS server, providing RFC1918 addresses on internal interfaces, and global address (or no addresses) on the public inetrface.
Look at the "ip dns view" command so you can present differnt DNS responses by interface.

How can I find out the mail server from email address?

Hi:
How can I find out the mail server from email address?
for example: If I know the email address is [email protected],
how to find the pop3 and smtp mail server?
THANK YOU

You can't tell by the email address since you can pretty much put whatever you want in there (especially if the SMTP server is not filtering anything).
The header may be able to tell you something. There is a Received header value which looks like it has the routing information although I am not sure if this is a complete trace or just the last hop the message took.

DNS Server Performance

Hey!
I'm preparing my 70-410 exam
and would like to nkow some troubleshooting tips when it comes to DNS server performing slowly.
Thanks for your help in advance.

If your Mac is getting good speeds, but page loads are still low it certainly could be due to poor DNS performance.
I have been using 4.2.2.1 and 4.2.2.2 as my DNS for a few years and the performance was much better than those supplied by my ISP.
I have also fooled around with OpenDNS on my PC and it works nicely. I am happy with the performance on my Mac, so I have left it alone. You can get all the info you need on OpenDNS on their page found HERE.

DNS Server in IOS?

Does any version of the IOS include a DNS server? To make a long story short, I just need one record to be resolved on a non-routed subnet and am hoping I have can have a router act as a DNS server.
