Nope. (with one exception)  MAC addresses are used at level 2, which
doesn't leave the LAN.
It's not a one to one thing anyway - a given IP could have multiple
MAC addresses or vice versa.

The exception? If *it* tells *you* (rather than the other way around)
- e.g. some service (like an snmp agent) tells you what the MAC
address is when you ask it.
