Does anybody know where I can locate a list of MAC address prefixes that belong specifically to wireless NIC cards? I am looking for a method of discovering what devices on my network are wireless devices. Art Houle e-mail: houle@acns.fsu.edu.

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.... -- Valdis Kletnieks Operating Systems Analyst Virginia Tech

i've used/seen cards with these prefixes: 00:e0:29 - smc 00:02:2d - orinoco/wavelan cards (lucent/agere) however, there's nothing to stop the vendor from using a given prefix for wired cards as well. more to the point, it's relatively trivial to change the hardware address of the card, so all bets are off (read as: mac address filtering is useless). -- |-----< "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."

some other possibilities, use SNMP to read from access point. Lucent APs and WPs support(Unofficially) it. If you need perl/shell script let me know. Read from the switch port to which your wireless basestation/bridge is connected to. -antony

The NetStumbler tool (www.netstumbler.com) appears to have a fairly good MAC to vendor mapping, and may have helpful information. Their database shows a full range of MAC addreses, which could give you a starting point. OTOH, it's easy enough to change MAC addresses - you'd probably be better off pulling the information from your access point - the lucent gear certainly allows you to do so, but I can't speak for any others. cheers! ========================================================================== "A cat spends her life conflicted between a deep, passionate and profound desire for fish and an equally deep, passionate and profound desire to avoid getting wet.

based on the reply stream so far I guess there aren't really that many "standards lawyers" here. IEEE maintains a list of "AUI prefixes". You can get a copy various places, I'd start with www.iana.org. Or, walk around your organization and your local computer store and write down the first three bytes on the mac address listed on the box (assuming they document it on the box) sure, you can change the mac address. you can also convert a pringle's can into a radio antenna. bfd. if you are looking for a first-order approximation don't worry about that.

The problem with this is that manufacturers have the option of not allowing the IEEE to disclose this and many (most) wireless card makers also make wired cards that share the same AUI prefix. R.

lucent and aironet (later cisco) never made wired cards so I wouldn't expect that. also, I think that the non-ieee lists tend to have more/better data on prefixs. I bet snort or etherpeek or ethereal or sniffer or someone like that has a decent aui list. also, of course, manufacturers know that no real people use network management so why bother to document your aui? a manufacturer who keeps their aui secret is offering to live in a non-sales-enhancing position...

they might never have made cards you could plug into your pc or mac, per se, but cisco at least has made quite a name for itself by manufacturing a large pile of *other* networking equipment. a fair amount of which uses the same addressing style. :) -- |-----< "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."
but the AUI header was assigned back when it was aironet. 3com, as it exists now, is in fact an old terminal server company called Bridge, which mutated into a router company, which got bought by this silly little pc ethernet card vendor called 3Com, etc.etc.etc. At 12:11 AM 11/10/2001 -0500, Andrew Brown wrote:
