Not really very useful; besides the rather obvious ambiguity, there
simply isn't a lot of locality in MAC space.

There *may* be some value in specifically the OID portion of the MAC
address (the 01 for Ethernet plus three octets), but I have yet to hear
a compelling enough use case for everyone else to take the load time
penalty.
