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
