We used to have a client that we hosted their domains on our DNS. They have moved to a different host a while ago - like months ago. Now suddenly, in the past 48 hours, I'm seeing a bunch of these in my logs:


named[1920]: client 216.199.46.11#58010: query (cache) 'travelhacker.com/A/IN' denied named[1920]: client 70.46.90.166#1064: query (cache) 'travelhacker.com/A/IN' denied named[1920]: client 208.109.78.200#31909: query (cache) 'travelhacker.com/MX/IN' denied named[1920]: client 38.102.229.30#32772: query (cache) 'travelhacker.com/MX/IN' denied named[1920]: client 208.53.147.132#41941: query (cache) 'travelhacker.com/CNAME/IN' denied named[1920]: client 70.46.90.166#1064: query (cache) 'travelhacker.com/MX/IN' denied

I have bind setup to deny recursive lookups, and it's doing what it's supposed to do there. However, is there any harm being done here? Should I be looking into some way to have this stopped somehow?

You may have still been listed as a name service in the root servers for some reason or someone is using an out of date cached version of their information. That's their problem, not yours and it probably isn't going to do anything except suck up bandwidth.

If it isn't happening too often I wouldn't worry about it since it should correct itself eventually.
