| − | ===DHCP server configuration===
| |
| − | ----
| |
| − | A <b>DHCP</b> (<b>Dynamic Host Configuration Protocol</b>) server is a service that can automatically configure the TCP/IP settings of any device that requests such a service. If you connect a device that has been configured to obtain an IP address automatically, the DHCP server will lease out an IP address from the available IP pool and the device will be able to communicate within the private network.
