10.4.3 Caching looked-up names – nscd, dnsmasq, pdnsd, bind9

If your nameserver is slow to respond then you may want to use nscd to cache the results of things that are looked up using the libc6 resolver.

If you want to cache results for other hosts on your local network then you may want to run a caching forwarding nameserver such as dnsmasq or pdnsd.

If you wish you can also use bind9's named as a caching forwarding nameserver. It is a heavy program, though, so unless you need its advanced features you are better off with one of the packages mentioned earlier.

All of these packages work well with resolvconf.
