"J.J.Bailey" : i'd like to have an infinite cache someplace for reference. i suggest using zero as the expire time to do this. ip allocations change far less frequently than domain information. i suggest adding a second expire value for ip entries in the cache. for example, i'd use 720 hours for domain info and 4320 hours for ip info. * Make it a library!
