I seem to recall that one of the predecessors of Comcast (Roadrunner? AT&T Broadband?) actually assigned real, honest-to-goodness hostnames to each customer that were derived from the MAC address. Maybe that's not the case
any more.
I know that bootp uses 48-bit ethernet addresses to assign IP addresses and DHCP servers support BOOTP client sematics (that is, here is my MAC address, now give me my IP address). From http://www.ietf.org/rfc/rfc2131.txt?number=2131 DHCP supports three mechanisms for IP address allocation. In "automatic allocation", DHCP assigns a permanent IP address to a client. In "dynamic allocation", DHCP assigns an IP address to a client for a limited period of time (or until the client explicitly relinquishes the address). In "manual allocation", a client's IP address is assigned by the network administrator, and DHCP is used simply to convey the assigned address to the client. A particular network will use one or more of these mechanisms, depending on the policies of the network administrator. -- _/_/_/ Bob Pearson gottadoit@mailsnare.net _/_/_/ "The best way to get information on Usenet is not to ask a _/_/_/ question, but to post the wrong information." - Aahz' Law
