What is the purpose of DHCP server?

A DHCP Server is a network server that automatically provides and assigns IP addresses, default gateways and other network parameters to client devices. It relies on the standard protocol known as Dynamic Host Configuration Protocol or DHCP to respond to broadcast queries by clients.

Why does DHCP have 2 ports?

The DHCP has two port numbers, that is, port 67 for the DHCP server and port 68 for the DHCP client. This means that the DHCP client selects only port 68, rather than a temporary port that is not used. The two ports are selected because a response from the DHCP server can be broadcast.

Why UDP is used in DHCP?

DHCP uses UDP as its transport protocol. DHCP messages that a client sends to a server are sent to well-known port 67 (UDP—Bootstrap Protocol and DHCP).

What are the respective UDP port numbers used by DHCP servers and clients for communication?

What incoming server port does DHCP rely on to receive requests?

DHCP is a method for automatically assigning addresses and other configuration parameters to network hosts. DHCP uses UDP as the transport protocol on ports 67 and 68 (the client uses its own port 68 as the source port with port 67 as the destination port on the server to send the request to the server).

What will happen if there are multiple DHCP servers on a network?

If you are considering multiple DHCP servers, remember that multiple DHCP servers cannot share any of the same addresses. If you use more than one DHCP server in your network, each server must be configured with their own unique IP address ranges.

How does DHCP assign IP addresses?

DHCP Address Allocation Methods

Automatic allocation. —The DHCP server assigns a permanent IP address to a client from its. IP Pools.
Dynamic allocation. —The DHCP server assigns a reusable IP address from. IP Pools.
Static allocation. —The network administrator chooses the IP address to assign to the client and the DHCP server sends it to the client.
