Safari, Open DNS ect.

Recently was having problems with Safari being slow. Came across a forum, possibly even an Apple Discussions thread, and someone mentioned changed the DNS settings, for Safari to run faster - (http://reviews.cnet.com/8301-13727_7-10354948-263.html).
I don't have much knowledge about it, other than reading this article (http://www.labnol.org/internet/tools/opendsn-what-is-opendns-why-required-2/2587 /) but I changed the settings nonetheless.
Seems to be working a littler faster, but just in case... is it possible to change back to my original DNS settings? Would the numbers be the same as on my wifi? Thanks.

It will automatically revert to your networks gateway/router address - usually 10.0.1.1. It's displayed in your Network prefs.

Safari 5 issues resolved since using OPEN DNS/working fine here at WEGMAN'S

my issues have been resolved since using OPEN DNS codes. have been using the internet at home and also am using it at WEGMAN'S right now and seems to run fine. i'm satisfied! btw, cnet.com gave Safari 5 an excellent rating.

HI,
Use Open DNS Free / Basic No more problems with DNS. Includes anti phishing filters.
For Safari. Empty the cache more often. From your Safari menu bar click Safari / Empty Cache. A faster way is: Option + Command + E on your keyboard.
And from your Safari menu bar click Safari / Preferences then select the Advanced tab.
Click: Change Settings next to: Proxies. That will prompt the System Preferences / Network pane
Make sure none of the boxes are selected under: *Select a protocol to configure* If there are, deselect the box, then click: OK.

TRY OPEN DNS OR GOOGLE'S NAMEBENCH TO RESOLVE SAFARI 5 ISSUES

HI,
2 DAYS AGO, I EXPERIENCED ALL THE PROBLEMS YOU GUYS ARE HAVING WITH THE SAFARI 5 UPGRADE. I THEN SAW A POST ABOUT OPEN DNS CODES CLICKED ON THE ARTICLE ABOUT IT AND PLUGGED IN THE APPROPRIATE NUMBERS. HAS WORKED FINE SINCE. SOMEONE ELSE POSTED ABOUT DNS CODES AND USING GOOGLE'S NAMEBENCH WHICH I HAVEN'T TRIED SINCE THE INTERNET SPEED I AM AT CURRENTLY SUFFICES. HERE IS THE LINK FOR GOOGLE'S NAMEBENCH FOR ANYONE WHO WANTS TO DOWNLOAD IT: http://code.google.com/p/namebench/ USING THE OPEN DNS RESOLVED ALL ISSUES THAT SAFARI 5 HAD WHEN I UPGRADED. WORKS FINE AND I HAVEN'T EXPERIENCED ANY PROBLEMS SINCE. HERE'S THE ARTICLE EXPLAINING OPEN DNS: http://appletoolbox.com/2010/06/safari-5-0-hangs-while-loading-pages-fix/

No, that link doesn't work but the information is correct!
Adding DNS codes to your Network Preferences, should give good results in terms of speed-up as well as added security:
If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:
208.67.222.222
208.67.220.220
(You can also enter them if you click on Advanced and then DNS)
Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:

OPEN DNS HAS SOLVED MY SAFARI 5 ISSUES

Thought previously that the disk permissions would completely resolve the issue but was still experiencing some problems that others have described. Saw another post on open dns so googled it and found this article: http://appletoolbox.com/2010/06/safari-5-0-hangs-while-loading-pages-fix/
Plugged in the numbers for the open dns and all seems to be fine in the Safari 5 universe now!

Open DNS follow-up report

Interestingly, after a very positive experience by adding the open DNS numbers 208.67.222.222 and 208.67.220.220, I found today that every time I tried to open Safari it knocked me offline. So I've now resorted back to the number originally assigned to me.
What's going on with Safari?

Jake,
One Verizon DSL account; one Westell 6100 modem
Check with Verizon and find out what the max download / upload speeds should be.
If this is the plan you purchased: http://www22.verizon.com/residential/highspeedinternet/
*"And we’re constantly looking for ways to make our DSL faster—recently upgrading our Starter plan to 1 Mbps* download and our Turbo plan to 7.1 Mbps."*
1 Mbps download / 7.1 Mbps is hardly high speed.
You can check your upload/download speeds here. http://www.speedtest.net/
To realize faster download and uploads speeds you would need to upgrade your service.
This is more then just a DNS issue.

Open DNS

My very much up-to-date Safari has been exceptionally neurotic. The day begins at lightning speed, then slows down, then, from time to time, Safari simply knocks out my internet connection.
I've seen others here suggesting one could add 208.67.222.222 and 208.67.220.220 in their DNS menu. I haven't done it yet, simply when I click "+" to do so, my current numbers disappear. I was hoping the two series of numbers above could be added rather than substituted, so that if there was a problem with the two suggested numbers, I could revert back to the old ones, provided by, I assume, my internet provider Verizon.
Any thoughts on the above?

How did you add them?

Having trouble setting up Open DNS with mac.

When I try to set up Open DNS I get the following error message:
Safari can’t open the page “http://192.168.1.1/Basic.tri” because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes, and then try again.
I have a Linksys router. I can get the router so save the settings using my Microsoft laptop, but I get an "oops" error message from Open DNS saying I am not set up on their site and just sends me back to step one. Does this sound familiar to anyone?

No, you cannot put the router in front of the modem.
You might look for any information your ISP gave you for your modem, such as a user guide. Or use the instructions at OpenDNS for a Motorola router, it should be similar. Remove the router and directly connect just one computer to the modem and try to access the modem's built in utility, as you have with your Linksys router. Motorola's default address appears to be "http://192.168.10.1/", the default username is "admin", and the password "password". If you encounter a question about obtaining the DNS service dynamically, check NO, then handset the OpenDNS servers, save and possibly restart the modem.
If you are successful in configuring the modem, go back to the router and leave the DNS settings blank, as well as on each computer. Then the computers should receive the service dynamically from the modem.
After all that, hopefully the OpenDNS website detects you using their service and allows you to proceed with setting up your account.

Open DNS? Why do we have to do this, all of a sudden?

I'm one of the folks who has been experiencing this inexplicable hanging/not loading web pages and slower connection since I upgraded to Snow Leopard and the new Safari.
I did this DNS thing, which is fine, I understand what it means -
but I never had to do that before, and so I don't understand why I have to do it now, and why isn't my clever computer doing it automatically?
My 67 year old mother would never have known this if I didn't come along and fix it! LOL
So is this something that will be incorporated in a future update so people like my mother don't have to be so savvy, or is this the kind of thing we have to keep doing as new things get added?
Is this the only thing that is making my Safari hang on some websites that weren't hanging before all the new updates? Is there some other reason? I've done nothing new to my connection, it's the same DSL as before, and my ISP seems to show no problems at all.
Thank you for your help.

I wonder myself why Carolyn has the same answer on countless postings of just switching to Open DNS? Actually their not a bad DNS provider. But people are right to question why their current DNS servers that their ISP use are all of a sudden the cause for Safari nor loading pages. If that were the case I would think the ISP provider would be flooded with complaints. Considering the fact also that a Windows computer using IE 8 or Firefox with the same ISP is not affected tells me that its not the DNS servers and that changing to Open DNS would not provide the best solution. As I have also been affected by this issue and have traced it more to Safari and Snow Leopard then any other issue.
Do I have a solution? No. But suggesting that its a DNS issue is not on target.

Open DNS and shortcuts?

I'm not sure what's going on, but Safari 4 is not exhibiting it's usual behavior when it comes to shortcuts. Or at least I think it's shortcuts.
When I used to type in "website" it would automatically go to "website.com" but now it takes me to the Open DNS guide instead of the website.
Anyone have any idea why this is suddenly occurring?

This has been an annoying issue since upgrading to Snow Leopard. It's one of those minor but incredibly irritating nuisances scattered throughout the OS. I know it was sort of a luxury to have it auto-complete the domain but when a feature like this goes missing you begin to realize how much you took it for granted. Is there a hack/fix for this?

TS1398 How do I Disable open DNS resolver on my iPad.

I just got an iPad for Christmas and I keep getting emails saying one of my devices is on an open DNS. How do I check my iPad to confirm whether it is causing the problem.
Thanks
Ed

On the iPad: Settings > iCloud and turn Safari off (if you don't have any other devices you want it to share with)
and/or
On the Mac: Apple Menu > System Preferences > iCloud and turn Safari off

A Concern About Open DNS

It is bad for download performance not to use your ISPs local DNS servers.
When you use foreign DNS servers, many websites will mis-identify your location, and send you to farther away places to download the website, rather than the local, faster location.
For example, your Software Updates from Apple, which go through Akamai, who will send you to a slower, more distant server for the download.
In addition, as the switch to IPv6 begins, sites such as Google/YouTube will not enable you for IPv6 because you aren't using your ISPs DNS server, which they use to decide whether to give you an IPv6 website address, or just the IPv4 address.

Adding DNS codes to your Network Preferences, should give good results in terms of speed-up as well as added security:
If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:

208.67.220.220
(You can also enter them if you click on Advanced and then DNS)

Whilst in System Preferences/Network you should also turn off 'IPv6' in your preference pane, as otherwise you may not get the full speed benefit (the DNS resolver will default to making SRV queries). If you want to know what IPv6 is:

Open DNS vs TWC DNS (Dallas)

Should I use an open DNS or stay with TWC DNS (Dallas, TX)?
Are there really benefits to speak of as a second year Computer Engineering student?
Thanks all.

This is a comment on OpenDNS and other public domain-name system (DNS) services, such as Google DNS. You should use such a service if it solves a problem for you, and not if it creates problems you don't already have. To summarize:
1. Using public DNS will probably not make your network faster, and may make it slower.
2. It will probably not stop your browser from being redirected when you try to connect to a valid web address.
3. It will not make you safer from malware attacks.
4. It could cause confidential information to be compromised.
5. It has other privacy implications that you should take into account.
A DNS server resolves the human-readable "domain name" of an Internet host, such as www.apple.com, to the numerical address by which that host can be reached. The process is analogous to looking up a phone number by name. There is no chance that changing the DNS server you use will have any effect on a network problem not related to name resolution.
There are two valid reasons why you might want to use a public DNS service:
The DNS servers provided by your ISP are misconfigured (perhaps deliberately) or don't perform well.
You have a use for the filtering controls provided by OpenDNS and others.
Although some DNS services are touted as responding faster than others, there will be no noticeable difference if your ISP is delivering what you pay for. Most likely, the difference in response time among the DNS servers available to you is on the order of a hundredth of a second or less. But under some conditions, public DNS will significantly slow down network performance. Here is a case in point.
A content-distribution network (CDN), such as the one used by Apple to deliver software updates and iTunes content, relies on the location of the DNS server to optimize performance. If your query goes to a distant server, you may get slow downloads of Apple content, among other things. From the report of a test carried out by a networking consultant:
We listed 9 CDNs that would benefit from supporting/using edns-client-subnet, and only two actually support edns-client-subnet: CDN77 and ChinaCache. Others, including Akamai, Internap and CDNetworks, do not currently. This really is too bad, because from the performance data we collected, it is clear these CDNs deliver (much) worse performance currently in many countries to Google DNS and OpenDNS users.
Another reason often given for using public DNS is to avoid "redirection," that is, false results from a query for a valid domain name. Ethical ISP's do not intentionally redirect valid DNS queries, though it might happen unintentionally because of a misconfiguration; for example, because the address of a network host has recently changed, or because of a "poisoning" attack on the DNS server. Recently, some low-quality commercial ISP's such as CenturyLink have taken to redirecting DNS queries for search engines such as Google. Do not tolerate this practice. If your ISP is doing it, then you should demand that the redirection be stopped, or else switch to another ISP. Note that many ISP's may, and OpenDNS certainly will, redirect invalid queries to ad sites, in violation of published standards for DNS.
Some ISP's have been said to re-route all DNS queries to their own name servers, regardless of where the queries were directed. This is another intolerable practice. I don't know of any commercial ISP that is currently doing this, but if yours is, you won't be able to use a public DNS service, even if you change the network settings on your computer or router.
If your Internet access is provided by an employer or institution, rather than a commercial ISP, then you have to take what is dished out.
The claims on the OpenDNS website that it blocks malware attacks such as "Flashback" are false advertising. A DNS service does not and cannot block anything. All it can do is to selectively refuse to answer queries. It's trivial for a malware attacker to evade such controls. It's just as easy to evade the parental controls offered by OpenDNS. Nevertheless, you may find those control features useful, despite their limitations. Here is an example of an ASC user who had undesirable results from OpenDNS content filtering.
There is one exception to the rule that OpenDNS and Google DNS don't improve performance. The "prefetching" performed by modern web browsers, including Safari, may confuse some DNS servers, with the effects described in this Apple Support article. The article suggests testing OpenDNS, Google DNS, or another third-party DNS service as a possible way to overcome the problem.
If you need to switch DNS providers because of a misconfiguration of your ISP's servers, the change will most likely only need to be temporary. The problem may be resolved automatically within a matter of hours.
If you intend to use public DNS, such as OpenDNS, on a long-term basis, you should be aware of the privacy implications. As a user of the free service, you are not an OpenDNS customer, and the service provider — a for-profit corporation — doesn't have a contract with you. The marketers to whom OpenDNS sells access and information are its customers.
OpenDNS will know, and store, the address of every Internet server you use from now on. This is from its privacy policy:
When you use our Services, OpenDNS stores certain DNS, IP address and related information about you to improve the quality of our Service, to provide you with Services and for internal business and analysis purposes.
Concerning personal information, the policy states:
...[I]t is disclosed to entities that perform marketing services on our behalf or to other entities with whom we have joint marketing agreements...
You can't opt out of those disclosures. Read the privacy policy carefully and draw your own conclusions. The privacy policy of Google DNS seems to be somewhat more benign, but again, you should judge for yourself.
That's not the worst of it, though. The practice of hijacking nonexistent domains followed by most public DNS services could result in leaking confidential information to a hacker:
For example, consider the "same origin trust model" used for Web cookies. If you're holding a cookie for GOOGLE.COM and you can be fooled into following a link to KJHSDFKJHSKJHMJHER.GOOGLE.COM, and the resulting NXDOMAIN response is remapped into a positive answer to some advertising server, then you're going to send your cookie to that advertising server when you send your HTTP GET request there. Not such a bad thing for a GOOGLE.COM cookie, but a real problem for a BANKOFAMERICA.COM cookie.
To emphasize, NXDOMAIN remapping is not something that only happens when you randomly mistype a domain name. It can be exploited deliberately by malicious links placed on any web page. In the case of OpenDNS, the result would be that a cookie intended for another server would be sent to the OpenDNS web server instead. A rogue OpenDNS employee, or anyone who managed to break into the web server, might then be able to impersonate you on another website. If this scenario seems far-fetched, it's the stuff that network exploits are made of.
See also a brief. somewhat outdated, critique of OpenDNS on a Harvard Law School blog, with a response from the company's founder.

Open dns blocking sites

hello. all of a sudden i am getting open dns blocking some websites. it is my imac and latest v's of safari and firefox. i have changed the dns servers but wonder if i am putting the right ones in or if it is something else i should be doing. this is a new problem i never had before. do i have to call my cable company?

There is certainly no downside to use OpenDNS.

OPEN DNS not supported by APPLE?

I understand from talking to someone who is an apple service provider that Apple does not support the use of OPEN DNS. He told me was able to upgrade to Safari 5 with no problems using his default settings. I have been fine since using OPEN DNS. Prior to this, I was experiencing all the problems most of you have seem to have been experiencing since the Safari 5 upgrade (freezing, etc).
Should I try to delete the Safari 5 I have and download a new one? It sounds like people are still having the same issues. Why wouldn't Apple support OPEN DNS? My understanding is that it is perfectly safe to do so?

Safari opens to a page other than what I've defined in Preferences

This has me stumped...
I'm running Mountain Lion 10.8.4. When I open Safari (6.0.5), it does not open the homepage (Google). Instead, it automatically opens another website (http://pregnant.thebump.com/pregnancy-week-by-week/25-weeks-pregnant.aspx?MsdVis it=1). However, if I click the Home button on the browser, it does go to my homepage. This happens every time Safari is opened, regardless of the last page or tabs that were open the last time Safari was closed. This only happens with my wife's user, and only in Safari. It does not occur if I open Chrome as her user. Things I've tried...
Resetting the homepage preferences in Safari / Preferences.
When I go to Safari / Extensions, there are no extensions listed. When I go to home folder / Library / Internet Plugins, the only one in there is Picasa.plugin. I tried moving it to the desktop, resetting Safari, closing Safari, and the problem still exists when I open Safari back up.
I tried something similar with the Mac HD / Library / Internet Plugins folder. Took them all to the desktop, reset Safari, closed Safari, opened Safari. Problem still exists.
I've tried the Devolop / Empty Caches menu item. I've tried “sudo killall -HUP mDNSResponder” in Terminal to reset the DNS.
The only thing that seems to work is when I hold Shift as I open Safari. Only if I do that does it correctly go to the homepage. I'm out of ideas. Help?

Back up all data.
Triple-click the line below on this page to select it:
~/Library/Saved Application State/com.apple.Safari.savedState
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item selected. Quit the application if it's running. Move the selected item to the Trash. Relaunch the application and test.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

Safari, Open DNS ect.
