binding
|
Collection of configuration parameters, including at least an
IP address, assigned by a DHCP server to a DHCP client. A binding
can be dynamic (temporary) or static (permanent). Bindings are stored
in the DHCP server's binding database.
|
|
conflict
|
Problem that occurs when an address within the IP address pool
is being used by a host that does not have an associated binding in
the DHCP server's database. Addresses with conflicts are removed from
the pool and logged in a conflicts list until you clear the list.
|
|
DHCP client
|
Host that uses DHCP to obtain an IP address and configuration
settings.
|
|
DHCP options

Configuration settings sent within a DHCP message from a DHCP
server to a DHCP client. For a list of DHCP options, see RFC 2132, DHCP Options and BOOTP Vendor Extensions.

Dynamic Host Configuration Protocol (DHCP)
|
Configuration management protocol you can use to supervise and
automatically distribute IP addresses and deliver configuration settings
to client hosts from a central DHCP server. An extension of BOOTP,
DHCP is defined in RFC 2131, Dynamic Host Configuration
Protocol (DHCP).

|
Device that passes DHCP messages between DHCP clients and DHCP
servers. A gateway router is sometimes referred to as a relay agent.

assignment to DHCP clients. The address pool is associated with a
subnet on either a logical or physical interface.

lease
|
Period of time during which an IP address is allocated, or bound,
to a DHCP client. A lease can be temporary (dynamic binding) or permanent
(static binding).

IP address to which a DHCP client can transmit router solicitation
requests.
|

Windows Name Service (WINS) server

by hosts running NetBIOS over TCP/IP (NetBT) to register NetBIOS names
and to resolve NetBIOS names to IP addresses.
