What is an IP address? – Definition
IP address, or Internet Protocol, is a system for identifying devices connected with the Internet or a local network. A unique string of numbers allows us to locate the server. In Internet Protocol version 4 an IP address was encoded in 32-bit form.
It consists of 4 8-bit fields (usually in decimal format) separated by periods. The IP address is composed of two parts: the network part (the first one) and the host part.
What is the Use of IP Address?
There are 2 types of IP addresses: static (permanent) and dynamic. In the first case, the number is persistently assigned to the server, although it may be used by more than one user. Using a dynamic IP address, the string of numbers restarts every day or when reconnecting to the network. IP address doesn’t always turn out to be a precise way for locating hardware and users. We are currently using the Internet Protocol version 6 (IPv6), where each of IP addresses consists of 128-bit numbers. They are also divided into classes, depending on network sizes.
