It would not surprise me if the first bytes of the MAC were 52:41:53:20
(or xx:52:41:53:20 if it has a media-type byte).
That's a RAS server requesting addresses for clients - whether it has
any or not.
I have the following in the config for ISC DHCP
if (substring (option dhcp-client-identifier, 1, 4) = "RAS ") {
~ ignore booting;
}
