  DHCP Protocol -- Boot Message

Category: PROTOCOLS      

Application: DHCP Protocol      

The Dynamic Host Configuration Protocol (DHCP) is an automatic configuration protocol used on IP networks. Computers that are connected to IP networks must be configured before they can communicate with other computers on the network. DHCP allows a computer to be configured automatically, eliminating the need for intervention by a network administrator. It also provides a central database for keeping track of computers that have been connected to the network. This prevents two computers from accidentally being configured with the same IP address.

DHCP is not normally forwarded at the Network (OSI Layer 3) level. However, DHCP can be routed when using a DHCP Relay.

This SonicWALL signature identifies legitimate DHCP traffic.
