different ken here, BTW - that feature is called ARP,Address Resolution Protocol, the cable modem has learned the ethernet mac address to IP address conversion for your NIC card. You either wait for the "time to live" (TTL) of the ARP table entry to expire and refresh grabbing your new mac address, OR you wipe it clean with a Reboot or an arp -d (delete) command if available. It's not a bug, it is supposed to work that way. Nothing on a network really "talks" in terms of names or IP addresses, it really is done using MAC addresses at the low end. IP addresses were invented as a way to standardize around the different sizes of MAC addresses between ethernet , token ring, arcnet, etc that were around at the time. The local nets build ARP tables to translate the virtual IP address into a real hardware address on the local network. Novell's IPX was based on using MAC addresses originally as I recall and then "zoning" them for more complex networks. > > -----Original Message----- > > From: Ken Plumley [mailto:[EMAIL PROTECTED] > > Sent: Thursday, August 07, 2003 10:47 AM > > To: [EMAIL PROTECTED] > > Subject: RE: Ethernet & DHCP Fails on Cable Modem to Internet > > > > > > Jason, > > > > The nic is an SMC EZ 10/100 the driver loaded for it > > is the RealTek RTL-8139. > > > > I tested the nic with a fixed IP and was able to > > access other machines on the LAN. > > > > Ken
