I have been setting up a Verizon DSL account for a friend of mine and
the best I can figure it out is Verizon runs Netware and DHCP. The MAC
address is stored in the arp cache for 45 minutes (supposed to be
seven). The MAC address and your presently assigned IP address are
paired and you either have to wait for the entry in the arp cache to
expire or to release the MAC address by a command. The command in
Windblows is; go the DOS screen and enter ipconfig /release. Then if
you want a new address type ipconfig /renew.
I don't know what the commands are in Linux or Unix. Perhaps the man
pages can give you more info.
