DHCP deals with IP configuration, so I'd rather classify it as > part of layer 3, with IP and ICMP. AFAIK, it does not provide any > service to any application but to the IP layer itself, just like ICMP. [1] lists is as an application level protocol. My original thought was UDP, hence L4. Furthermore, there are lots of dhcp options (ntp-server, local-proxy-config to name a few that are actually used) that deal with client's configuration that's not related to IP configuration directly.
