No... But... If you have someone open a command prompt at the computer in question, they can type in "ipconfig /all". The entry called "Physical Address" is the MAC.

MAC's are basically a serial number from the manufacturer. The first three entries determine the company, while the last three determine the hardware serial. Therefore, they have no tie to the IP specifically.

If you are on a windows box, and you are on the same subnet as the device you are trying to determine the mac of, you can ping the IP, then type "arp -a" to see what the mac is.

Also, if both devices are connected to a cisco switch, you can type "show arp | include x.x.x.x" to determine what the mac is.  You might have to ping the device first from the switch to populate the arp table the run the "show arp | include x.x.x.x"

I should have premised that the "show arp | include x.x.x.x" be ran from within the cisco switch.

If you're on the same physical subnet (no routers or switches separating your machine from the target), ping the address, then type:

    arp

The ping will cause an arp request to be broadcast, which the target IP address will respond to (usually, unless it's configured not to). Your computer caches arp responses and the arp command displays the contents of the cache.

The cache exists to reduce network broadcast traffic. Entries in the cache have a lifetime after which they're purged; the default lifetime varies and is configurable.
