: I currently subscribe to Adelphia and use the modem they provided me.
: However, I want to use another cable modem which I own and am trying
: to get its MAC address to give to Adelphia. Under WinXP, how does one
: go about doing this? The modem's manual provides a URL from which to
: get configuration info, but as the modem isn't registered with
: Adelphia I can't connect to it. Likewise, the modem (a 3com Home
: Connect) has a couple of numbers printed on it, but none is labeled as
: a MAC address. Finally, as I'm using XP, winipcfg doesn't work. Any
: help is much appreciated.
The MAC address will start with one of the following values:
Ethernet Codes: Vendor codes
"Ethernet hardware addresses are 48 bits, expressed as 12 hexadecimal
digits (0-9, plus A-F, capitalized). These 12 hex digits consist of
the first/left 6 digits (which should match the vendor of the Ethernet
interface within the station) and the last/right 6 digits which
specify the interface serial number for that interface vendor.
Ethernet addresses might be written unhyphenated (e.g. 123456789ABC),
or with one hyphen (e.g. 123456-789ABC), but should be written
hyphenated by octets (e.g. 12-34-56-78-9A-BC).

02608C 3Com IBM PC; Imagen; Valid; Cisco; Macintosh
080002 3Com (formerly Bridge)
08004E BICC [3com bought BICC, so may appear on 3com equipment as well]
3C0000 3Com dual function (V.34 modem + Ethernet) ..."
For example, my 3Com OfficeConnect LAN Modem's (ISDN router) MAC address
starts with 08004E.
