DHCP

How it is used

Spelled out letter by letter. Engineers talk about the DHCP server, a DHCP pool or scope, DHCP leases and DHCP reservations. A typical problem is a pool that runs out of addresses, so new devices get no IP.

Example sentences

1. The guest Wi-Fi DHCP pool is full, so new phones aren't getting an address.

2. Set up a DHCP reservation for the printer so its address never changes.
