Retrieving the MAC address of remote machine?

How can i retrieve the MAC address of remote machine? I know the IP address.

Is there anyway of getting the MAC address programatically from the ARp
table?

Thanks in advance.

Hi Rajash,

if the client is on your LAN (no routers - hops - in between you and the
client) first ping the client then check ARP -a. Look for the IP you pinged
and next to it should be ARP. If there is a hop (router, FW, ...) between
you and the client you have no option to see the MAC address.

Unless both computers have NetBIOS installed (e.g. all pre-W2k MS
systems). Running the following command from a DOS/CMD shell will give
you a list of registered NetBIOS names and the MAC address of the remote
system.

nbtstat -A 192.168.1.1
nbtstat -a mypc

<replace the sample IP or computername with the appropriate value.>


If the remote system obtained it's IP from a DHCP server, you should be
able to retrieve the MAC from the DHCP server's database.

There are a number of other possibilities, but, as Rajash indicated, the
common ones require access to a device on the same segment as the system
whose MAC address you're trying to retrieve (since MACs aren't normally
used for network functions across segments).
