White listing comes with any blacklist. The blacklists in particular being discussed were the @dynamics, like the PDL and dynablock at easynet. Both lists quite clearly state how they build their lists and what they are designed to block (dynablock only takes out dialup, and PDL takes out all dynamic addressing). Query , How is it determined that the address in question is dynamic or not ? Who/how/what makes that determination ? This is the core of my concerns .
It's usually determined via in-addr.arpa, 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. ---------------------------------------------------------------------- Jon Lewis *jlewis@lewis.org*| I route System Administrator | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
