Hi all.
I somehow have managed to get opendns blocking access to websites on my home network. I am the administrator and the only person who would have (accidentally) installed opendns, although when I search through my computer, I don't see any files relating to this.
I have done a little research and know that I would have to installed this at some point myself, but I can't recall doing this, and would really like it gone.
So far, I have contacted my ISP and asked them to issue me a new IP Address. That did not work. I tried ipconfig/flushdns, ipconfig/release & ipconfig/renew, all did not work.
I also tried the following:

Control panel
Network and Sharing Center
Manage Network connections
right click on local area connection, properties
Internet protocol version 4
obtain an IP address automatically

these steps did not work either.

If anyone can tell me how I can remove opendns from my computer or router settings, then I would be very happy. thanks.

Re: How to remove Opendns?

That's what we needed to know!

Your gateway ip is the address you use to logon to the router.

Before doing so though you need to know your ISP dns ips.
Sometimes these are listed on their web site or you may need to call them to get them

Great. Logon to your router, go the the wan setup page and put in the top two dns entries and save the configuration. Reboot the router.

Re: How to remove Opendns?

I figured you would remember that from the time you setup the router to use opendns.

you put 192.168.1.1 into your internet browser
you hit enter
you are presented with your routers logon page
it asks you for the account and password
you enter the required information
you are now logged on to your router.

Re: How to remove Opendns?

As I mentioned at the beginning of my post, I did not intentionally change these settings, and I certainly did not login to my router. I'm beginning to think i'm the victim of a DNS Hijack. Anyway, i'm currently following your instructions and will report back with an update. I'm very grateful for your help so far. Thanks.

Re: How to remove Opendns?

Hi,
I entered one of the above IP ID's into the "default dmz server" (the only place available to enter numbers) and got the following error message:
"This IP Address should in the same subnet as the LAN IP Address"

maybe i got the wrong page. I'm using a Netgear Router.

Re: How to remove Opendns?

No you went to the wrong section you want DNS server probably under advanced depending on brand of router.

Please give make and model if you are having trouble finding DNS.

Go to basic settings if it asks for login select no get an ip address dynamically and select to get a dns server address dynamically and click apply.
