Why connect two DHCP servers with different IP addresses?

  MaxEvans 16:39 06 Dec 14

so for an assignment at college we had to configure a router connected to two switches which both had a server connected to them.

the computers were connected via dhcp to either server however each side had a different IP. we have now been asked to justify as to why two servers were used with different IP which I cannot quite produce a business orientated answer.

I can understand connecting two dchp servers on same IP to increase fault tolerance but I do not understand using two separate IP addresses.

As far as I am aware only one device can be used for DHCP on a network. DHCP hands out the ip addresses to devices as they connect. Servers really should have a static ip address. They need to have different ip addresses so they can identified correctly. As you say having 2 servers improves fault tolerance and depending on exactly how they are configured could speed up delivery of data.
