I use a sort-of hybrid solution: My DNS registrar (Hover.com, FWIW, but
most should allow it) lets me register a CNAME record pointing to an
otherwise "throw away" dynamic dns name, which my home server keeps
Even if the somewhat janky free dynamic DNS name goes away or changes
(which has happened at least once in the past, IIRC), the CNAME address
remains constant (albeit disconnected for short periods when the dynamic
DNS does something annoying to try to value-add)

I've been working-up the motivation to actually do-away with the free
dynamic DNS service and use my cheapie static virtual host to do the
dynamic DNS. Still firmly in the "can't be bothered" territory, though.
