Why UDP is used in DHCP?

A DHCP server relies on the standard protocol DHCP to respond to broadcast queries by clients. UDP is used instead of TCP because TCP does not support broadcasting, and 2 of the total DHCP messages use broadcasting (DISCOVER and REQUEST).

What is the difference between DHCP and IPAM?

IPAM (IP Address Management) is the administration of DNS and DHCP, which are the network services that assign and resolve IP addresses to machines in a TCP/IP network. Simply put, IPAM is a means of planning, tracking, and managing the Internet Protocol address space used in a network.

What is enterprise DNS?

Enterprise DNS is an enterprise-class implementation of the domain name system (DNS) that resolves external and internal queries for large organizations in a centrally managed, scalable, automatable and secure way.

What is DHCP relay Pfsense?

DHCP requests are broadcast traffic. Broadcast traffic is limited to the broadcast domain where it is initiated. To provide DHCP service on a network segment without a DHCP server, use the DHCP relay to forward those requests to a defined server on another segment.

What is DHCP and why is it important?

DHCP (Dynamic Host Configuration Protocol) is a protocol used to provide quick, automatic, and central management for the distribution of IP addresses within a network. DHCP is also used to configure the proper subnet mask, default gateway, and DNS server information on the device.

What is the function of DHCP?

The core function of DHCP is to assign addresses. DHCP functions at the Application Layer of the Open System Interconnection (OSI) reference model, as defined by the International Organization for Standardization (ISO) and the Telecommunication Standards Section of the International Telecommunications Union (ITU-T).

What is DHCP relay/ IP-Helper-Address?

This IP address enables the DHCP server to determine which subnet should receive the offer and identify the appropriate IP address range to offer. The DHCP relay agent sends the local broadcast, via IP unicast, to the DHCP server address 172.16.1.2 specified by the ip helper-address interface configuration command.

What is DHCP and how DHCP works?

How DHCP work. DHCP provides an automated way to distribute and update IP addresses and other configuration information on a network. A DHCP server provides this information to a DHCP client through the exchange of a series of messages, known as the DHCP conversation or the DHCP transaction.
