Hi Aleks, We discussed doing this once at my organization and someone astutely pointed out that considering that this is DNS, the better solution would really be to run a local caching DNS server, e.g. bind9 and point resolv.conf to 127.0.0.1 with forwarders to your ISP's nameservers. Well, what they actually pointed out was that since we already do this everywhere, we're already getting in-memory caching that's designed expressly for DNS results, for free :) running a local caching DNS server is basically a good idea anyway, and obsoletes the need for caching DNS results in any particular software. -Jared
