International Mobile Equipment Identity - A 15 digit, unique serial number assigned to a mobile phone. IMEI consists of five groups of numbers. the first group represents the manufacturer the second sequence identifies the Type Approval Code (TAC) or model number the third represents Final Assembly Code (FAC) the fourth is the device serial number the fifth is a spare single digit (usually 0).

An International Mobile Subscriber Identity (IMSI) is a unique number associated with all GSM and Universal Mobile Telecommunications System (UMTS) network mobile phone users. It is stored in the Subscriber Identity Module (SIM) inside the phone and is sent by the phone to the network. It is also used to acquire other details of the mobile number in the Home Location Register (HLR) or as locally copied in the Visitor Location Register (VLR). In order to avoid the subscriber being identified and tracked by eavesdroppers on the radio interface, the IMSI is rarely sent and a randomly generated Temporary Mobile Subscriber Identity (TMSI) is sent instead. An IMSI consists of three components: Mobile Country Code (MCC) Mobile Network Code (MNC) Mobile Subscriber Identity Number (MSIN) The traditional SIM card issued by a mobile operator contains a single IMSI for the issuing operator. The IMSI is then used to authorize access to mobile networks, whether the home network or another network the device has roamed.

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers.

Internet Protocol Address is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.

Internet Protocol version 6 (IPv6) is the version of the internet protocol that provides an identification and location system for computers on networks and routes traffic across the internet.
