I have a network having two servers that are occasionally booted. I wish to maintain DHCP services even during a boot of one server.
One of the servers currently has a DHCP server that gives static IP addresses. It gives addresses only to users with an allowed MAC address, and each user has a fixed IP. No dynamic IPs are there.
Is it possible in this setup to run two DHCP servers in the same network in different servers for redundancy? I'm not looking for a solution where the IP address sets of two servers are disjoint; I'm looking for a solution where the IP addresses both servers give are static and the same.
I am mostly interested about the general concept: can DHCP as a protocol support two DHCP servers giving same static IP addresses? Do clients get confused if they get a response from two servers with the same lease IP address? This is why I didn't specify what DHCP server I am using. I am specifically not requesting instructions for host / server configuration.
I originally asked this in Network Engineering, but they seem to have a habit of closing perfectly valid non host / server configuration related network engineering related questions using some unknown random algorithm, saying that the question is about host / server configuration (which it isn't; it's about the protocol) and the question is about a protocol above OSI layer 4 (which it is, but then again they have numerous DHCP questions there and not all get closed).
