Moving all unknown links to others and adding second and top level domain (example.com) as description would be good enough for me. (Which could be done by a simple regular expression.)

Hmmm ... i think that something like this: /(http:\/\/)?(www.)?([^:\/]*)(.*)/ would get \3 as the "domain" (actually all of the hostname minus any www)  (I'm a big fan of regex )
