DHCP is a network protocol to used to configure IP networks. A DHCP server listens to UDP port 67 and dynamically assigns IP addresses and other network parameters to DHCP clients.
Why does DHCP use 2 ports?
The reason TWO reserved ports are used, is to avoid ‘waking up’ and scheduling the BOOTP server daemons, when a bootreply must be broadcast to a client. Since the server and other hosts won’t be listening on the ‘BOOTP client’ port, any such incoming broadcasts will be filtered out at the kernel level.
