You call up their new upstream, say you're a representative of XYZ, and customer ABC does not have permission to announce your netblocks. I know InterNAP requires that they get consent from the netblock contact, I don't know about other companies. And so it doesn't happen as a prank, while on phone with them, tell the person to send an e-mail to the netblock contact, you open up the e-mail and read it back to them for verification, it seriously can't be that complicated. kthkxbye. -- Omachonu Ogali [email protected] http://www.informationwave.net
