How do I setup multiple DHCP servers?

- Divide the pool of IP addresses so that each server is responsible for a range of addresses and there is no overlap of responsibility.
- Choose NIS+ as your data store, if available.
Can you have a secondary DHCP server?
To provide secondary service, the DHCP server confirms configurations that were supplied by another DHCP server on the network. It does this when the primary server responsible for those IP addresses cannot respond. After a waiting period, the secondary server responds in its place.
Why does DHCP have two ports?
The reason TWO reserved ports are used, is to avoid ‘waking up’ and scheduling the BOOTP server daemons, when a bootreply must be broadcast to a client. Since the server and other hosts won’t be listening on the ‘BOOTP client’ port, any such incoming broadcasts will be filtered out at the kernel level.

What is the difference between DHCP discovery and DHCP offer?
DHCP Discovery (DHCPDISCOVER) – Sent by the Client seeking a DHCP Server. DHCP Offer (DHCPOFFER) – Sent by the DHCP Server to offer an address (and other DHCP options) to the Client. DHCP Request (DHCPREQUEST) – Sent by the Client to accept the lease for the offered address.
What happens if a DHCP server receives a DHCP request first?
Whichever DHCP Server’s DHCPOFFER packet is received first by the Client will “win”, and that Server will receive a DHCPREQUEST from the Client. This can actually cause a Denial of Service condition depending on the circumstances. In a past job, I worked in the NOC of a regional ISP.
