A database of URL shortening services

I found myself with a need for a list of URL shortening services but I couldn't find a good one. Where I define "good" as "available in a sensible format and kept up-to-date".

So I've started my own.

You can query it via DNS (but it's not a DNSBL/RHSBL, as the return value needs parsing).

It is used like this:

$ dig +short txt bit.ly.type.spam.ms

Where r means "redirect service" and p means "public" with a semicolon as the separator.

See the FAQ for more information. Let me know if it misses any URL shorteners (eventually I'll add a submission form, but I just wanted something that worked to start with).
