Well, you didn't mention what platform you were running on. Solaris, for 
instance, has "nscd", which can cache DNS resolution information (among 
other kinds), although I've had problems in the past with its 
address-sorting and TTL behaviors, so I usually disable the "hosts" part 
of its caching functionality whenever possible. I'm sure there are other 
mechanisms on other platforms that can perform this name-lookup-caching 
function.

Beyond that, if you want a multiplatorm solution, you might take a look 
at the lwresd stuff in the BIND distribution. I've never worked with it, 
though, so don't consider that a recommendation.
