Question : BIND9 is not caching responses.

I have a BIND9-based DNS server set up here at home.

I serves as the master for a couple of internal domains, and everything else is resolved via a forwarders directive in the config file.

The problem is that the server goes out the forwarders to get an ip address every single time a domain name is requested.

If i request www.google.co.uk 10 times in a row, it does 10 requests out to the forwarders. This seems to indicate that the server is not caching responses.

How can i make it cache responses so that subsequent requests for the same domain name dont require a request to the forwarders.

Answer : BIND9 is not caching responses.

Are You sure You are using the local bind9 as resolver (/etc/resolv.conf)
Have You configured caching nameserver in bind(zone ".") or just forwarders?
