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. ---------------------------------------------------------------------- Jon Lewis *[email protected]*| I route System Administrator | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
