What is DHCP and its uses?

Dynamic Host Configuration Protocol. Dynamic Host Configuration Protocol (DHCP) is a network management protocol used to automate the process of configuring devices on IP networks, thus allowing them to use network services such as DNS, NTP, and any communication protocol based on UDP or TCP.

What is DHCP on router?

The Dynamic Host Configuration Protocol (DHCP) Reservation feature allows the router to reserve the lease of an IP Address for use of a specific device on your network, effectively ensuring that the router does not assign the IP Address to other devices in the network.

What is IP DHCP snooping?

In computer networking, DHCP snooping is a series of techniques applied to improve the security of a DHCP infrastructure. When DHCP servers are allocating IP addresses to the clients on the LAN, DHCP snooping can be configured on LAN switches to prevent malicious or malformed DHCP traffic, or rogue DHCP servers.

What port is DHCP on?
