I would imagine some sort of Internet Authority on Routing. There are already quite a few authorities for other such things on the Net. But perhaps a better solution would be for everyone to register with a Routing Authority. We already require any one that wants to use a domain name to register, and if you want a block of IP space or a BGP number you have to register with ARIN. I realize there are registries like RADB and RIPE, but these don't seem to be used to their full potential. Some backbone providers still enter in route filters manually, which seems a little obsolete considering the number of routes being advertised. -- James Smith, CCNA Network/System Administrator DXSTORM.COM http://www.dxstorm.com/ DXSTORM Inc. 2140 Winston Park Drive, Suite 203 Oakville, ON, CA L6H 5V5 Tel: 905-829-3389 (email preferred) Fax: 905-829-5692 1-877-DXSTORM (1-877-397-8676) It's Unix or nothing!
