JUST WONDERING HOW IP ADDRESSES WOULD BE ALLOCATED IN A SUBNET ENVIROMENT,

WOULD YOU HAVE TO CREATE NEW SCOPES FOR EACH SUBNET,AND HOW WOULD THE SCOPES KNOW THAT A PARTICULAR RANGE OF IP ADDRESSES WAS FOR THAT AREA OF THE NETWORK AND NOT TO ALLOCATE THEM ANY WHERE ELES?

HOPE I HAVE MADE THIS CLEAR,

Hy,

First things first, please DO NOT SHOUT LIKE THIS...

Oke, to answer your question.

Subnets are always connected by routers, and one of the specs of a router is that it doesn't forward broadcasts, a DHCP discover packet is a broadcast. (MAC of al FFF's)

Then you can do 2 things.

Set up a DHCP server on each subnet.
Use a DHCP relay agent to encapsulate the DHCP traffic so it can pass a router.

Your DHCP server will then know wich IP it must give based on the address of the DHCp relay agent (assuming that your DHCP server is configured with multiple scopes)

Kind regards,

P.S If someone thinks this statement is incorrect please say so..that way we all keep focused..
