Novell DNS/DHCP Management Utility Administration Guide
Allocation of IP addresses, either temporary or permanent, is one of the two
primary services provided by DHCP. The client requests an IP address, and the
DHCP server (or collection of DHCP servers) provides an address and
guarantees not to give that address to another client within a specified time.
Additionally, the server tries to return the same address to the client each time
the client requests an address. The period of time over which an IP address is
allocated to a client is called a lease.
DHCP supports three methods of IP address allocation:
Dynamic BOOTP allocation
Dynamic DHCP allocation
Manual (or static) allocation
A network can use one or more of these methods. The network administrator
decides which methods to use.
Dynamic BOOTP enables a DHCP server to assign permanent addresses to
BOOTP clients from a pool of addresses. No manual configuration of the
client is required prior to address allocation.
Dynamic DHCP allocation is the only method enabling automatic reuse of
addresses no longer required by a client. Dynamic DHCP allocation is useful
for assigning an address to a client that will be connected temporarily to the
network or for sharing a limited number of IP addresses among a group of
clients that do not require permanently assigned IP addresses.
Dynamic DHCP allocation is also useful for assigning an IP address to a new
client installed on a network on which IP addresses are scarce and must be
reclaimed when older hosts are removed. An additional benefit to dynamic
DHCP allocation is that when a client's lease is renewed, the DHCP server
refreshes the client's configuration.
