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.
