DHCP servers

You can enable DHCP on your Connect IT 16/48 device to assign IP addresses to clients, using either:

• The DHCP server for the device's local network, which assigns IP addresses to clients on the device's local network. Addresses are assigned from a specified pool of IP addresses. For a local network, the device uses the DHCP server that has the IP address pool in the same IP subnet as the local network.

  When a host receives an IP configuration, the configuration is valid for a particular amount of time, known as the lease time. After this lease time expires, the configuration must be renewed. The host renews the lease time automatically.

• A DHCP relay server, which forwards DHCP requests from clients to a DHCP server that is running on a separate device.
