Appendix III. Glossary

Bridge

      A node connected to two or more administratively indistinguishable
      but physically distinct subnets, that automatically forwards
      datagrams when necessary, but whose existence is not known to
      other hosts.  Also called a "software repeater".

Gateway

      A node connected to two or more administratively distinct networks
      and/or subnets, to which hosts send datagrams to be forwarded.

Host Field

      The bit field in an Internet address used for denoting a specific
      host.

Internet

      The collection of connected networks using the IP protocol.

Local Address

      The rest field of the Internet address (as defined in [3]).

Network

      A single Internet network (which may or may not be divided into
      subnets).

Network Number

      The network field of the Internet address.

Subnet

      One or more physical networks forming a subset of an Internet
      network.  A subnet is explicitly identified in the Internet
      address.

Subnet Field

      The bit field in an Internet address denoting the subnet number.
      The bits making up this field are not necessarily contiguous in
      the address.

Subnet Number

      A number identifying a subnet within a network.
