Resolve MAC Address to Manufacture

I know that the each Ehthernet Adapter has it´s own MAC Address. And in it´s MAC Address has the manufacture name. For example I think "Realtek". How do I extract it´s name from the MAC Address ?

Hi ramoreia,
Progematically I dont know, but you can find out here http://coffer.com/mac_find/

You can't. The MAC address simply contains a manufacturer *code* and a unique card ID. You need a look-up table to get the manufcaturer ID.

Have a look at http://www.synapse.de/ban/HTML/P_LAYER2/Eng/P_lay280.html or http://coffer.com/mac_find/

If you import the WMI type library (C:\WINNT\system32\wbem\wbemdisp.tlb) then it is possible to query the netword card(s) using the WMI functions. Not really for the feint of heart since WMI can be quite complex when you first see it. But perhaps there are easier solutions too.

How do I use wbemdisp.tlb ?

gmayo

It might be easier to grab the information on a website, like the one I pointed out (although I believe it is out of date), store it in a file, and access it as required. Then you simply parse the file to obtain the manufacturer ID.

Yeah, I posted a couple of minutes after you with the same link, I didn't see yours until after I posted. However, it doesn't have an up-to-date copy of the entire data on one page, you have to use their search engine. Unless I've missed a link somewhere...

Hey guys,

Is here a way if I give an IP show me the MAC Address ?

gmayo

No. IP addresses have no relation to MAC addresses. However, if you want to find out the MAC address of a card that *currently* has that IP address, then yes you can usually.

No, don't do that. The very last post was posted after the answer was accepted - look at that one instead.

My problem is this. I got the snmp project that gives me the MAC Address of all Ethernet Adapters in the PC. That´s great. But the BIG Problem is to know which MAC Address is from what Adapter ? Because it not usefull to know the MAC Address if you don´t know from what Adapter is from. Agree with me ? If you help me solve this one I´ll give all of the points I have.

gmayo

I haven't done that myself. Read the links provided and you will find an answer to your problems.
