I've heard about caching DNS servers, and "tiny DNS", and I > wondered if they might suit my needs. As with bind, setting up tinyDNS's dnscache program is pretty trivial. See the instructions here: http://cr.yp.to/djbdns.html (He even has different HOWTOs for the different usage scenerios) Note one thing: if you install tinyDNS from ports, your svscan directory will be /var/service instead of /service to comply with hier(7).
