Question : BIND DNS Server Logs full of "unexpected RCODE (SERVFAIL)"
We don't use this serve to host any zones at all. We just use it as a caching DNS server really. We don't have any DNS servers to forward requests to either. So I'm wondering why I get 20,000 error messages a day per server. I understand my server is trying to look up DNS information across the internet and is not finding the information or is rejected which is causing these errors.
I have an ACL to only allow lookup requests from people inside my network. So this DNS server cannot be used by people on the outside. I use webmin to manage the bind server.
Some examples..
unexpected RCODE (SERVFAIL) resolving '199.252.32.89.in-addr.arp
a/ANY/IN':
194.54.128.226#53: 2 Time(s)
unexpected RCODE (REFUSED) resolving '101.54.6.207.in-addr.arpa
/ANY/IN': 209.53.4.150#53: 1 Time(s)
unexpected RCODE (REFUSED) resolving '91.32.194.173.in-addr.arp
a/PTR/IN':

unexpected RCODE (REFUSED) resolving 'ns2.fastserve.net/A/IN': 216.176.200.5#53: 1 Time(s)
What can I do to fix this?
