Apache Friends Support Forum

hello,
I'd like to assign a dns name so that my IP changes to something like: apachefriends.org, does anyone know of a *free* service?

Top of my head:
http://www.no-ip.com/
http://dyndns.org/
or you can purcahse a domain and use the following services:
http://www.zoneedit.com/
http://dnsexit.com
