Dynamic Host Configurations Protocol(DHCP) is a protocol that give an IP to the host with its own IP address, gives it a subnet mask and a default gateway. The process happens in four stages.
1. The host that wants to join a network finds a DHCP server, it broadcasts a DHCP discovery message over the network. At this point the host has no subnet address or the IP of the DHCP server, so it just broadcasts to all nodes. 2. The DHCP server will discover the message that the host is broadcasting and send a reply, which would contain a proposed IP address, network mask, lease time and a transaction ID.
