DynDNS, Dig It

This is just a plug for DynDNS.org, who provide all sorts of useful services related to DNS and mail. Basically they take care of a bunch of things that in an ideal world shouldn’t be necessary: If you have broadband but your DNS keeps shifting; if you can’t get to your ISP’s mail-sending SMTP machine; and so on. Some of the services are free, and the rest are ridiculously cheap, and it seems to Always Just Work. Check it out.
