OpenDNS Troubleshooting

Description:

So every now and then, I will notice that our OpenDNS service will not be blocking queries. I usually perform the following steps to resolve.

To Resolve:

1. Login to each DNS server and Clear DNS Cache then wait 5 minutes.

2. Pull up a command prompt and type:

   ping 208.67.222.222
   nslookup whoami.akamai.net.
   netsh interface ip show dns
   nslookup -type=txt debug.opendns.com
   

3. Go to OpenDNS

4. Go to the test blocked site www.internetbadguys.com and ensure it is blocked by provider.
