How to assign IPs according to router IP?

[Robinson Tiemuqinke]

Hi,

 I've heard there is a way to assgin a same box (same
MAC address and same OS) different IPs according to
where(which networks) the dhcp request is sent from.
But I just can not find it now. Any one have the idea
how to fulfill it? It looks like some kind of "if ...
then ..." statements.

Thanks a lot.
