Another idea: for each A record stored, I can add a TXT record for the
current date. For instance, for today may 20th, I blacklist 192.0.2.1
and 192.0.2.2. I would have in my zone file:

1.2.0.192.bl.example.net IN A 127.0.0.1
2.2.0.192.bl.example.net IN A 127.0.0.1
20130520.bl.example.net IN TXT 1.2.0.192.bl.example.net 
20130520.bl.example.net IN TXT 2.2.0.192.bl.example.net 

That way I just need to perform a DNS lookup on current date to get all
the records I need to cleanup.
