Two dhcp addresses on the same interface

[birro]

Maybe this question is stupid, but does anyone know if it's possible (by using virtual interfaces) to have more
than one address assigned to the same (physical) interface from a dhcp server?

for example:

eth0 xxx.xxx.xxx.xxx (external address assigned from dhcp server)
eth0:0 xxx.xxx.xxx.xxx (also external address assigned from dhcp server)
and so on..

Just adding iface_eth0:0="dhcp" into /etc/conf.d/net did not work. (tried both after/before bringing the virtual interface up)

I have heard that dhcp servers only gives out one lease per mac address, so if that's true this might not be possible at all.

Please enlighten me =)

the dhcp server will give you an address based on your MAC address. So you may have to fake another MAC addresse for the second IP you need.

BTW I can understand why one may want two FIXED IP addresses, but why do you want two dynamic IP adresses on the same interfaces.

HTH
