No.

DHCP (Dynamic Host Control Protocol) is a method of providing clients network information from a router or DHCP server. It can tell a host what their IP address is, what the gateway is, what the DNS servers are, WINS servers, etc.

NAT (Network Address Translation) is the technology used by a gateway that allows a private ip address to access information on the public internet.

For example, You have a router (10.0.0.1) that acts as a DHCP server and DNS server. Something connects to your network and broadcasts a DHCP request, and is then given an ip address (10.0.0.5 for example) and told where to go to resolve domain names.

That client wants to connect to Google, it makes the request first to the name server through the gateway, and then information is sent back to the gateway. NAT Allows the gateway to get the information to the correct computer behind it even though it is not directly accessable. (Google can not directly access 10.0.0.5 and vice versa)

You have installed and configured a dhcp server on your network. you also have a web server on the same network. The web server requires the same ip address as the dhcp server what should you do?

The only way that could work is if the DHCP service and the HTTP service were configured and running on the same physical machine. Otherwise they could not use the same IP address. DHCP and HTTP do not have to be on separate machines (but it is a good idea to separate them in a network). A better question might be why the two services *require* the same IP address.

Can you configure two dhcp server on a same network?

yes, one can configure two dhcp server on a same network. But for doing this, one has to define different scopes in both dhcp server in order to avoid ip address conflict. Eg. one can configure a scope for a lan with network address of 10.0.0.0 as- 10.0.0.10- 10.0.0.100 in one dhcp server. while other scope would be 10.0.0.101-10.0.0.200 . In this way we can have to dhcp servers on a same network. Which ever dhcp server receives the request for the ip address will provide the ip address. IN case for servers, one can use mac bindingin both servers so that they obtain same ip address
