IP <--> MAC

[Guest]

Hello:

I know the IP address for remote server, the one
located outside the local network.

How can I get the MAC address for this remote
machine ?

thanks

In a CMD prompt

arp -a x.x.x.x

where x.x.x.x is the ip address

or

nbtstat -a x.x.x.x

where x.x.x.x is the ip address

Steve,

nbtstat -a x.x.x.x

doesn't displays info not for all IP.

---------------------------------------------------
It looks like this:

nbstat -A XXX.XXX.XXX.XXX

Host not found

thanks dave

The nbtstat trick will only work if the destination hosts in on the same
subnet as the machine you're using. Also, you will have had to have had
communications with the remote machine for it to be in the ARP table. I
recommend pinging the machine first.

If you have managed switches on your network, you can use these to find the
relationship between MAC address and IP addresses.

You cannot get any MAC outside the local segment but router's MAC only using
standard tools. Router doesn't not pass through ARP packets.
