How does computer find DHCP server?

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

How does a DHCP client work?

How does DHCP work as a client / server protocol?

Address assignment with DHCP operates according to the Client/Server principle: the connection-seeking device requests an IP address configuration from a DHCP server, which in turn accesses a database from which the network parameters that need to be set are acquired.

Where can I find the DHCP server address?

To begin, send the client a DHCPDISCOVER package with the target address 255.255.255.255 and the source address 0.0.0.0. With this so-called broadcast, all network users are contacted to locate available DHCP servers and inform them of the address request. Ideally, there’s only a single server so that there are no complications with the assignment.

What happens if the DHCP server is not available?

The DHCP client now locally saves all of the data that was received and connects to the network. If the server is no longer available or the IP has been assigned to another client during the configuration process, it responds with DHCPNAK ( DHCP not acknowledged ).
