Hi, it seems some addresses are unable to be resolved by Norton DNS while any other DNS public or private DNS (even web dns lookup service) can resolved those addresses...Is it a configuration problem on your part or that Norton DNS as more strict rules?
I had to remove the Norton DNS so we could work with the site we needed too : www.dlvdm.com
Your help would be appreciate to resolve this matter..is this a behavior that could be change in the future so it work like all other DNS services?
The issue look related to same issue in this post
