DHCP is a layer-4 protocol, most commonly transported over UDP. UDP port number 67 is the destination port of a server, and UDP port number 68 is used by the client
This setting will depend on your network's settings: Usually, if your network is not configured in a special way, either "Autodetect" or leaving it blank should work.
It works on the "application layer", because the data is handled at that layer. However, the information it transfers (distribution of IPs) transcends "layers". BTW, It uses UDP (not TCP), at the "transport layer" on ports 67 and 68. Edit - "Application" is 7 on the OSI model I believe, but often referred to as a different number with different models
Layer 4 : The Transport Layer
Layer 7: The Application Layer
physical layer Layer 1
Switches / Bridges and hubs work at data link layer, but there are layer three switches which operate at network layer. Dhruv
hub work at physical layer of osi model
Data Link Layer
Routers work with many different kinds of protocols, for different purposes. They work with layer-3 protocols such as IP and IPX, with routing protocols such as RIP, EIGRP, and OSPF, with VLAN-specific protocols, with DHCP, Telnet, and many others more.Routers work with many different kinds of protocols, for different purposes.

Layer 2, Data Link.
PGP works at the Layer 6 - Presentation level.
