Re: Is there a reason
I assume you mean IP addresses... MAC addresses are only used on the local network segment. But even then, you can use whatever MAC you want so long as its not already in use on the network segment and has the 16th bit in the address set (to differentiate it from a multicast address). I've seen quite a bit of MAC spoofing on public networks since most non_free wifi spots authenticate with it, so if you grab one of a machine that is disconnecting, you can steal the session and get a free connection.
