It's usually determined via, whois data, or direct
information from the provider.  When MAPS was freely available, I used to
periodically email them updates on our IP space (please add these dial
ranges, please remove these others).  I'm sure others did the same.
AFAIK, they had at least one FTE who's job it was to maintain the DUL.

Those large providers who stole copies of the DUL before MAPS pulled the 
plug on them, and continued to use them without maintenance still annoy 
me as we've run into issues multiple times with space removed from the DUL 
still being in their private copies.
