IP
IP is an acronym for Internet Protocol. It is a protocol used for
communicatingdataacrossaninternetnetwork.
IP is a "best effort" system, which means that no packet of information
sentover isassuredto reachits destinationinthe sameconditionitwas
sent.Eachdeviceconnectedto
aLocalAreaNetwork(LAN)orWideArea
Network(WAN)isgivenanInternet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of
the Internet Protocol,IPv6, which would have
 128‐bits Internet Protocol
addresses. This number can be represented roughly by a three with
