Dynamic Host Conguration Protocol
Dynamic Host Conguration Protocol (DHCP) is an application layer protocol that dynamically assigns IP addresses and other conguration
parameters to network end-stations, also known as hosts, based on conguration policies network administrators determine.
Figure 2. Client and Server Messaging
DHCP server
Network device oering conguration parameters to the client.
DHCP client Network device requesting conguration parameters from the server.
Relay agent Intermediary network device that passes DHCP messages between the client and the server when the server is
not on the same subnet as the host.
Packet format and options
The DHCP server listens on port 67 and transmits to port 68. The DHCP client listens on port 68 and transmits to port 67.
Conguration parameters are options in the DHCP packet in type, length, value (TLV) format. To limit the number of parameters that
servers must provide, hosts enter the parameters that they require and the server sends only those parameters. DHCP uses the User
Datagram Protocol (UDP) as its transport protocol.
