Mobile IP. Mobile IP (or MIP) is an Internet Engineering Task Force (IETF) standard communications protocol that is designed to allow mobile device users to move from one network to another while maintaining a permanent IP address. Mobile IP for IPv4 is described in IETF RFC 5944, and extensions are defined in IETF RFC 4721.
Care-of address. A care-of address (usually referred to as CoA) is a temporary IP address for a mobile device used in Internet routing. This allows a home agent to forward messages to the mobile device. [1] A separate address is required because the IP address of the device that is used as host identification is topologically incorrect—it ...
An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication. [1][2] IP addresses serve two main functions: network interface identification, and location addressing. Internet Protocol version 4 (IPv4) defines an IP ...
IPv4 address exhaustion is the depletion of the pool of unallocated IPv4 addresses. Because the original Internet architecture had fewer than 4.3 billion addresses available, depletion has been anticipated since the late 1980s when the Internet started experiencing dramatic growth. This depletion is one of the reasons for the development and ...
Mobile phone tracking is a process for identifying the location of a mobile phone, whether stationary or moving. Localization may be affected by a number of technologies, such as the multilateration of radio signals between (several) cell towers of the network and the phone or by simply using GNSS. To locate a mobile phone using multilateration ...
Click any recent activity entry to view its IP address as well as the date and time it was collected. If one is drastically different from the others, remove it and change your password. Be aware that there are some legitimate reasons why your history can show unfamiliar locations, such as your mobile device detecting the wrong location or ...
For mobile web browsing, the client IP address refers to the internet gateway machine owned by the network operator. For devices such as the BlackBerry or for phones using Opera Mini browser software, the IP address refers to an operator-owned internet gateway machine in Canada or Norway.
The main market forces that accelerated address depletion included the rapidly growing number of Internet users, who increasingly used mobile computing devices, such as laptop computers, personal digital assistants (PDAs), and smart phones with IP data services. In addition, high-speed Internet access was based on always-on devices.
