1.2.1.4 DHCP Server Module
The DHCP Server module is used to assign IP addresses to DHCP clients from the configured IP address database. When the server receives a request from a client, the DHCP server determines the network to which the DHCP client is connected, and then allocates an IP address that is appropriate for the client, and sends configuration information appropriate for that client. DHCP servers typically grant IP addresses to clients only for a limited interval. DHCP clients are responsible for renewing their IP address before that interval has expired, and must stop using the address once the interval has expired, if they have not been able to renew it.
