Automatic IP address numbering

What is automatic IP address numbering (DHCP)?

DCHP is an abbreviation for “Dynamic Host Configuration Protocol” and is a protocol for automatically configuring basic communication settings in IPv4 networks. If you set this function on the router and connected terminal, the IP address within the network will be automatically set.

Within the LAN, if the DHCP function is enabled on the router, IP addresses other than those of the router will be automatically assigned to the devices under the router. The figure below is an example of setting the router’s Lan side IP address to 192.168.200.1 and automatically assigning an IP to the connected terminal using DHCP.
