    This does work, I've used it. As somebody mentioned, the two subnets
have to be in different broadcast domains (different VLANs; not part of
the same DHCP "shared-network") and you only get one at a time based on
where the client is currently connected. 

    The only way to give one interface two IP addresses simultaneously
would be make its client ask twice with different client identifiers. I
am not aware of any normal DHCP client that does that.
