Way Back When, I think that IEEE was the party that handed out prefixes to be used as MAC addresses. I know several people have compiled lists at one time or another. There's a neat little app for palm OS handhelds called Ethertools*, that had a reasonably comprehensive list of the well-known ones. (*Of course similarly formatted MAC addresses are present on other multi-access mediums as well. I recall pulling out a lot of hair figuring out how 3Com ended up with what looked like two MAC's on every token-ring card. Turned out to be the same address, but token ring was small-endian vs. big-endian. Or vice versa.) -----Original Message----- From: Steven M.

belong specifically to wireless NIC cards? I am looking for a method of discovering what devices on my network are wireless devices.
Power down the wireless hub and see who calls? ;)
Seriously though - your wireless hub/transmitter may have a queryable arp table that will tell you what's not using the wire....
i've used/seen cards with these prefixes:
00:e0:29 - smc 00:02:2d - orinoco/wavelan cards (lucent/agere)
I'm sending this via a Lucent card with prefix 0:60:1d. A glance at my ARP table for a wireless-only segment shows 0:4:dd, 0:3:6b, 8:0:20, 0:0:c, 0:c0:b7, 0:d0:b7, 8:0:6a, and more. --Steve Bellovin, http://www.research.att.com/~smb Full text of "Firewalls" book now at http://www.wilyhacker.com

http://standards.ieee.org/regauth/oui/index.shtml -- Yours, J.A. Terranson sysadmin@mfn.org If Governments really want us to behave like civilized human beings, they should give serious consideration towards setting a better example: Ruling by force, rather than consensus; the unrestrained application of unjust laws (which the victim-populations were never allowed input on in the first place); the State policy of justice only for the rich and elected; the intentional abuse and occassionally destruction of entire populations merely to distract an already apathetic and numb electorate... This type of demogoguery must surely wipe out the fascist United States as surely as it wiped out the fascist Union of Soviet Socialist Republics. The views expressed here are mine, and NOT those of my employers, associates, or others. Besides, if it *were* the opinion of all of those people, I doubt there would be a problem to bitch about in the first place... --------------------------------------------------------------------

there are quite a few lists...i've found these so far. lists: http://www.cavebear.com/CaveBear/Ethernet/vendor.html ftp://ftp.cavebear.com/pub/Ethernet.txt http://standards.ieee.org/regauth/oui/oui.txt http://www.iana.org/assignments/ethernet-numbers ftp://ftp.iana.org/in-notes/iana/assignments/ethernet-numbers http://www.netsys.com/macaddr.html http://map-ne.com/Ethernet/vendor.html lookups: http://standards.ieee.org/regauth/oui/ http://coffer.com/mac_find/ general info: http://standards.ieee.org/regauth/oui/tutorials/EUI64.html

i find it far easier to just 'dig txt ##:##:##.et.graffiti.com' when i need to know. ps - i'm looking for capable secondaries for this zone -- |-----< "CODE WARRIOR" >-----| codewarrior@daemon.org * "ah! i see you have the internet twofsonet@graffiti.com (Andrew Brown) that goes *ping*!" andrew@crossbar.com * "information is power -- share the wealth."
