That's one way of doing it; a large cable ISP in the Netherlands required customers to phone in when they had fried their network card. Nowadays the cable modems handed out to subscribers allow configuration of this by the end customer. BUT: I don't think Chris and me were thinking about big bad ugly LANs with customers attached indiscriminately, though. With DSL provisioning systmes using RFC1483 bridged (do I have my buzzwords correct here?) the DHCP server can discriminate between customers based on VCI/VPI numbers instead, negating the need to look at the MAC address of the request. > Who was it that said, "if you can't identify at least 3 new problems > introduced by any solution, you don't understand the situation?" Or you don't understand ours. After all, it's currently all getting done already this way. -- Niels (who thinks IPv6 Router Advertisements are broken when hosts are multihomed)
