DHCP address allocation

DHCP supports the following mechanisms for IP address allocation.
Static allocation—The network administrator assigns an IP address to a client like a WWW server,

and DHCP conveys the assigned address to the client.
Automatic allocation—DHCP assigns a permanent IP address to a client.
•
Dynamic allocation—DHCP assigns an IP address to a client for a limited period of time, which is
