IGMP Internet Group Management Protocol
An Internet protocol that enables a computer to share information
about its membership in multicast groups with adjacent routers.
A multicast group of computers is one whose members have
designated as interested in receiving specific content from the
others. Multicasting to an IGMP group can be used to
simultaneously update the address books of a group of mobile
computer users or to send company newsletters to a distribution
list.
IGMP Snooping Snoop the IGMP packets on each port and associate the port
with a layer 2 muticast group.
Internet The global collection of interconnected networks used for both
private and business communications.
intranet A private, company-internal network that looks like part of the
Internet (users access information using web browsers), but is
accessible only by employees.
IP See TCP/IP.
IP address Internet Protocol address
The address of a host (computer) on the Internet, consisting of
four numbers, each from 0 to 255, separated by periods, e.g.,
209.191.4.240. An IP address consists of a network ID that
identifies the particular network the host belongs to, and a host ID
uniquely identifying the host itself on that network. A network
mask is used to define the network ID and the host ID. Because
IP addresses are difficult to remember, they usually have an
associated domain name that can be specified instead. See also
