How to remove a DNS entry from Network Preferences

When I checked Network Preferences today, I discovered 2 DNS servers listed in +System Preferences > Network > Ethernet > Advanced > DNS.+ There have never been any DNS servers listed there before.
One of them is my home router; the other is a server that to my knowledge I have never accessed. I did not add these servers to my system and have no idea how they got into my Network Preferences.
I would like to remove them but cannot find any way to do it. The addresses are greyed out and cannot be selected to be removed.
Yes, I unlocked the preference pane.
No, there are no DNS servers listed in my Airport configuration.
Both connections work fine.
I just want to remove the DNS server addresses.

I think I found the answer.
The grey DNS server entries are coming from my router. I can see them appear in the DNS pane when I connect the ethernet cable. Also checked my router and that's the DNS address specified in the router setup (Actiontec MI424WR). There is also no evidence of a potential DNSchanger/RSPlug/Jahlav trojan.
Based on info I found in the Verizon FIOS forums & DSLreports, the 71.242.0.12 address appears to be Verizon DNS server nsphil01.verizon.net, which would make sense as I have FIOS internet. But I don't quite understand why a WHOIS request on the address returns these server names: NS1.THOMASLORD.NET and NS1.ACCESSMYEMR.COM

    Hi,
    How can i remove a specific back stack entry in windows phone.In windows phone 8 NavigationService.RemoveBackentry() method is used similarly is there any way
    Thanks,
    Punith

    Did you meant Windows Phone 8.1 xaml or silverlight? For silverlight, NavigationService.RemoveBackEntry() is there & for WP8.1 xaml(RT), you can use :
    Frame.BackStack.RemoveAt(Frame.BackStack.Count - 1);

  • Unix command in ARD to remove DNS Servers from Network prefs?

    I need to know how to send a unix command to remove DNS Servers in Network preferences. I need the DNS Servers field to be blank. Can this be done?

    Our network administrator is getting ready to change the IP address of our DNS server. This means I have over 30 Macs that will be needing changes to their DNS settings. Since each machine is setup with limited access to the system prefs, that means I have to go to each machine and log in as the admin user to make this change. In the interest of saving time, is this something I can do with Remote Desktop and how? Would I use the same commands in this post and replace dns1 with our DNS' new IP address? Will this distrupt the users access to the network when I do so?
    Thanks for any help.

  • How to find and remove obsolete table entries from /SAPAPO/MATKEY table in EWM System.

    Hello,
    How to find and remove obsolete table entries from below tables in EWM System.
    /SAPAPO/MATKEY
    /SAPAPO/MATMAP
    /SAPAPO/MARM
    /SAPAPO/MATLOC
    /SAPAPO/MATMOD
    /SAPAPO/MATRQ
    /SAPAPO/MATLOTSZ
    Thank you,
    Pravin

    Pravin,
    First, tell me how you determine that these entries are 'obsolete'.
    Removing master data from SCM can usually be done using transaction WUF; however, you have to ensure that it is not re-sent to the SCM system, or you are just wasting your time.

  • How to remove the row entries

    HI,
    I have a row entry which contains radio button,dropdown,input field,calender.All the fields are dynamic
    All these fields(UI elements) are in one line and these are not in the table.If I add new entry(by clicking NEW ENTRY button),then a new row will be added dynamically with the same UI elements in the new row.Means every new row entry contains radio button,dropdown,input field,calender.
    Problem :- I want to delete one row entries.Means if I delete the 5th row entries,then it should remove all the UI elements(radio button,dropdown,input field,calender) from that 5th row entries only.
    I think I am clear about the requirement.
    Please suggest me how to remove a row entry.These UI elemenets are not table entry.
    Regards
    -Sandip

    Hi Sandeep,
    You can use the below code for deleting a row from table.
    int n = wdContext.nodeProducts().size();//size of node binded with table
    int leadSelected = wdContext.nodeProducts().getLeadSelection();
    // loop backwards to avoid index troubles
    for (int i = n - 1; i >= 0; --i)
    if (wdContext.nodeProducts().isMultiSelected(i) || leadSelected == i )
    wdContext.nodeProducts().removeElement(wdContext.nodeProducts().
    getElementAt(i))
    Hope this will help.
    Regards

  • How to remove credit card details from iPad 4. So I can download free apps from apps store??

    Please someone tell me how to remove credit card details from iPad 4, so I download free apps from App Store??

    None for payment
    After establishing the Credit Card account, you can remove the credit card information by editing your payment info, choosing "None".
    Note: You won't find "None" if you have not purchase anything with the Credit Card.

  • How to remove the credit card from the Apple id?

    how to remove the credit card from the Apple id?
    plz ITS urgently

    If the option to select "None" isn't appearing when you attempt to edit your payment information, then there is likely a billing issue with your last iTunes Store purchase(iTunes didn't receive payment from your credit card company for that order). Before you can remove your credit card, you have to pay for the unpaid order. You can call your credit card company and troubleshoot the billing issue with them, or try another card, or if you live in a country that supports iTunes Gift Cards, you can redeem one of those to pay for the order. Once you have done that, you should be able to remove your credit card info as outlined in http://support.apple.com/kb/ht1918

  • How to remove my credit card from the App Store

    How to remove my credit card from the App Store

    I used a pre-loaded credit card so when it ran out i had problems, primarily because it wont let me download or update anything until the "billing problem with the last transaction" was resolved. I dont really care if the purchase goes through but i want to be able to update stuff again and it wont give me the option to select 'none' under payment type. do i have to put another card on there just so i can "resolve the billing problem" and then i have  to take it off again or is there a way around this or is it a never ending cycle?
