Well, those errors aren't necessarily bad, unless you're also experiencing problems resolving names you think should be working :-)

Are things working okay for you, or are you unable to resolve DNS names?

If you're having problems, are you unable to resolve any DNS, or just some names?

i have these entries too. As far as I know these are queries that are prevented because your nameservers are not recursive except for local clients. so this is good.
The messages go away if you do not allow queries for local clients, but you will loose functionality, e.g. you can't do lookups from the bind module and such (Lookup WHOIS Information)

I can't resolve DNS. I've setup this server as ns1.myserver.com 5 days ago i changed nameservers in my domains to ns1.myserver.com ns2.mysecondserver.com. And nothing happens... I don't see changes !

I think this is connected with theese errors ! Maybe i have to turn off ipv6 or somewhat else ??? Help me plz !

ns1.volia .net - is a dns server of a datacentre, where my servers are hosted. It can't resolve them too !
