ICMP is an acronym for Internet Control Message Protocol. It is a protocol that generated the error resp

uting purposes. ICMP messages generally contain information about routing difficulties or simple

exchanges such as time-stamp or echo transactions. For example, the PING command uses ICMP to test an

Internet connection.

IEEE 80

IEEE 802.1X is an IEEE standard for port-based Network Access Control. It provides authentication to devices

attached to a LAN port, establishing a point-to-point connection or preventing access from that port if

ation fails. With 802.1X, access to all switch ports can be centrally controlled from a server, which

means that authorized users can use the same credentials for authentication from any point within the network.

IGMP

IGMP is an acronym for Internet Group Management Protocol. It is a communications protocol used to manage

the membership of Internet Protocol multicast groups. IGMP is used by IP hosts and adjacent multicast routers to

h multicast group memberships. It is an integral part of the IP multicast specification, like ICMP for unicast establis

connections. IGMP can be used for online video and gaming, and allows more efficient use of resources when

supporting these uses.

IGMP Querier

A router sends IGMP Query messages onto a particular link. This router is called the Querier.

IP is an acronym for Internet Protocol. It is a protocol used for communicating data across a internet network.

IP is a "best effort" system, which means that no packet of information sent over it is assured to reach its

ternet Protocol address, and this IP address is used to identify the device

uniquely among all other devices connected to the extended network.

The current version of the Internet protocol is IPv4, which has 32-bits Internet Protocol addresses allowing for in

excess of four billion unique addresses. This number is reduced drastically by the practice of webmasters taking

addresses in large blocks, the bulk of which remain unused. There is a rather substantial movement to adopt a

new version

for most of the Internet.
