pdnsd, written by Thomas Moestl, is a proxy DNS server with permanent caching (the cache contents are written to hard disk on exit) that is designed to cope with unreachable or down DNS servers (for example in dial-in networking).
pdnsd solves a frequently occurring problem with dial-up internet connections when the file /etc/resolv.conf changes after wwwoffled (a www proxy server) has been started up. (If you're interested in WWWOFFLE I also have patches available for it here.)
pdnsd allows you to configure one address as the DNS server for all your internet software. This can be localhost, but I personally use a separate machine that I've configured as a gateway to the internet for my home LAN.
pdnsd project can then be configured to contact your ISP's DNS servers when you make a dial-up connection.
