Internet Protocol, usually the abbreviation IP is used. It is the most common protocol for communication in computer networks and in the global Internet network. It is a set of rules describing data transfer over the network. It works at the network layer, which is the third from seven layers according to the ISO/OSI reference model and one of the four layers in the TCP/IP architecture.
Currently, IPv4 is the most widely used version of this protocol, which uses 32-bit addresses and provides about 4 billion addresses. Due to the running out of available addresses, the use of IPv6 is expanding, which uses 128-bit addresses and provides about 340 sextillion addresses.
Use of Internet Protocol in practice: Knowledge of Internet Protocol is particularly important for professionals in informatics, other managers and staff meet with IP in the form of the IP address (e.g. http://192.168.1.1.), which is used to distinguish the devices connected to the computer network. Otherwise, they don’t usually come with the Internet Protocol itself into contact.
