DHCP runs at the application layer of the OSI model.
IP operates at layer 3, this is the NETWORK LAYER in the OSI Model. Network+ Guide to Networks Fifth Edition Ch02, pg56, Figure 2-7
Layer 3 of the OSI model. An ICMP header follows the IP header of the IP packet.
Layer 3 i.e, network layer of the OSI model is used to IP addressing.
It works the same on all Layer 1 media. IP encapsulates OSI Layer 4 data. IP can carry voice, video, and other types of data, but "media independent" refers to the OSI Layer 1 medium that carries the data across the networks. IP, or any other communication, can occur without a physical (OSI Layer 1) medium

TCP operates at Layer 4 which is Transport of the OSI Model!
