MAC address -> IP address

[Howell]

I'm running a 15mi/min and can't think straight. What is the proper NT command to use to find the current IP address of a certain MAC address?

 

[honold]

ping the ip, then run arp -a

Nice tip Honold. Here is an article on that command:

I'll have to add that to my dictionary.

 

[Howell]

ping the ip, then run arp -a

That would be a good solution except that I'm trying "to find the current IP address of a certain MAC address". I know the MAC not the IP.

unfortunately windows doesn't ship with rarp

easiest way to do it is with a ping scan of your entire network (something like nmap will do) and then look in the arp -a table - or find a proper rarp app

Thanks honold. I thought it was the rarp command but I couldn't find it. I wonder what I was on when I used it before. Also, I discovered that for rarp to work you have to have a rarp server running on the segment.

For future reference, based on your techincal explaination I ran:

FOR /L %A in (1,1,255) DO PING -n 1 A.B.C.%A
arp -a |FIND /I "xx-xx"

Wouldn't the ipconfig /all do the trick? (if you're on the system with the NIC) This would list your adapaters and MAC's along with the IP associated with each...

he's talking about a remote system
