Configuring a Dynamic Host Configuration Protocol (DHCP) server
The Dynamic Host Configuration Protocol allows a
host on a network to receive configuration
parameters including an IP address at boot
time. DHCP is an extension of the
Bootstrap Protocol (BOOTP), but differs in
that DHCP can provide a complete set of
TCP/IP configuration parameters and allows the
dynamic assignment of IP addresses for a
DHCP offers the following advantages to
you as a network administrator:
SCO DHCP also provides:
The ability to provide complete TCP/IP configuration
information to any host connected to the network.
An IP address can be assigned to a
client for only as long as the client remains
connected to the network.
It allows a limited pool of IP
addresses to be shared among a number of
clients that do not require
permanent IP addresses.
Addresses become automatically available
again at the expiration of a period of time,
their ``lease'', without
requiring you to take any action.
SCO DHCP implements the server
aspects of the Dynamic Host Configuration Protocol
as defined in the Internet standards:
RFC 2131, and
The SCO DHCP server receives IP
addresses from the Address Allocation Server (AAS),
which provides the same service to other network services
that assign temporary IP addresses. See
``Configuring an Address Allocation Server (AAS)''.
The configuration parameters supplied by the SCO
DHCP server include those supported by
BOOTP, the set of parameters specified for
DHCP, and user-defined parameters.
