How to configure multiple ipaddress per mac address

[Ligesh]

 I am trying to setup a machine to have multiple ipaddresses using dhcp? Is this possible? Redhat doesn't seem to support it since they categorically say that eth0:0 won't support dhcp. So how can I specify in the dhcpd config file that a particular mac address has multiple ipaddreses? Does the protocol actually support multiple ips/ethernet card.

 Thanks in advance.
