43.3.1.3 DHCP Terminology
DHCP is based on the Server/Client model. The DHCP-server and DHCP-client exist in the DHCP running
conditions.
DHCP-Server
It is a device to distribute and recycle the DHCP-related sources such as IP addresses and lease time.
DHCP-Client
It is a device to obtain information from the DHCP server for devices of the local system to use, such as IP
address information.
As described above, the lease time is a concept appearing in the procedure of DHCP dynamic distribution.
Lease time
an effective period of an IP address since its distribution. When the effective period is over, the IP address is
to be recycled by the DHCP server. To continuously use the IP address, the DHCP client requires re-applying
the IP address.
