DHCP issues

[adrianwt]

Hi,

Let's say i have 2 dhcp servers lying on the same network segment but both are serving different scopes. In this case, which dhcp server will the clients retrieve the ip address from? Is there any ways to set priority to the dhcp servers or are they just load balanced? (Meaning the clients will obtain ip address of either dhcp server at different times)

Can anyone help me out?

Thanks!

Will get their ip address from the dhcp server that responds first.

If it doesn't leak oil it must be empty!!

But in this case how do i determine which server will respond first? Is there any ways to set this priority?

I don't think you can determine which one will answer first. It just depends on whichever receives the broadcast first. If the scopes are delivering different subnet ranges then I would seperate them with a router otherwise you will have a world of pain!

So in this case, can i say that the clients may randomly obtain ip addresses from either dhcp servers?

Yes - the first time they get the address. Until the lease runs out they will always get the same address. A good source of info is

If you wish to have the client get their address from a specific DHCP scope, you can try reserving an address for them by thier MAC address. If you do this for all the clients, it kinda defeats the purpose of DHCP over fixing the IP's of the clients at the client, but you atleast have know what addresses are being used. If you change a network card, you will have to update the reservation.
