Routers

DHCP requires non-volatile storage. This makes the task of DHCP service compatible with servers, but incompatible with dedicated routers. There are a number of server types that can be configured to both relay and serve DHCP, especially all-in-one Internet Gateways designed to be web servers, firewalls, and so forth. But there are no dedicated routers.

The DHCP RFC specifies that DHCP is not intended for use in configuring routers. The reasons are that in maintaining and troubleshooting a router, it is important to know its exact configuration, rather than leaving that to be established automatically, and that you do not want your router's operation to depend on the working of yet another server.

You may be able to configure some types of more general purpose computers or servers to get their IP addresses from DHCP and to act as routers. In addition, there are remote access servers, which are usually not true routers, which use DHCP to get IP addresses to give to their clients.
