How does computer connect to DHCP server?

How DHCP assigns IP addresses

1. A user turns on a computer with a DHCP client.
2. The client computer sends a broadcast request (called a DISCOVER or DHCPDISCOVER), looking for a DHCP server to answer.
3. The router directs the DISCOVER packet to the correct DHCP server.
4. The server receives the DISCOVER packet.

What port is DHCP?

The DHCP employs a connectionless service protocol UDP (User Datagram Protocol) and uses 2 UDP ports: 67 and 68. Port 67 is for a DHCP client (a destination port of a server), and port 68 is for a DHCP server (a destination port of a client).

Why does DHCP use two 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.

What is DHCP operation?

DHCP (Dynamic Host Configuration Protocol) is a protocol used by DHCP servers in wired/wireless IP networks to dynamically allocate a variety of network configuration data, such as a user IP address, subnet mask, default gateway IP address, DNS server IP address, lease time and so on, to client devices (DHCP clients).
