WHAT IS "IP ADDRESS"? YOU MUST KNOW !

THE IP ADDRESS

 (IP ADDRESS)
 "INTERNET PROTOCOL ADDRESS " is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication, data transfer etc.It is a unique number given to every mobile.

 An IP address serves two principal functions:
host or network interface identification and location addressing.

How many IP versions are there?

There are two versions of IP that currently coexist in the global Internet: IP version 4 (IPv4) and IP version 6 (IPv6).

Internet Protocol version 4 (IPv4) defines an IP address as a 32-bit number.However, because of the growth of the Internet and the depletion of available IPv4 addresses, a new version of IP (IPv6), using 128 bits for the IP address, It was developed in 1995,and standardized in December 1998.In July 2017, a final definition of the protocol was published. IPv6 deployment has been ongoing since the mid-2000s.

IP addresses are usually written and displayed in human-readable notations, such as

 172.16.254.1 in IPv4.
 AND
 2001:db8:0:1234:0:567:8:1 in IPv6.

 The size of the routing prefix of the address is designated in CIDR notation by suffixing the address with the number of significant bits, e.g., 192.168.1.15/24, which is equivalent to the historically used subnet mask 255.255.255.0.

The IP address space is managed globally by the Internet  Numbers Authority (IANA)and by five regional Internet registries (RIRs) responsible in their designated territories for assignment to end users and local Internet registries, such as Internet service providers(ISP).

 IPv4 addresses have been distributed by IANA to the RIRs in blocks of approximately 16.8 million addresses each.

 Each private network administrator or ISP assigns an IP address to each device connected to its network. Such assignments may be on a static (fixed or permanent) or dynamic basis, depending on its practicles and software.

THE DIFFERENCE BETWEEN IPv4 & IPv6 :---

The Difference Between IPv4 and IPv6 Addresses. An IP address is binary numbers but can be stored as text for human readers. For example, a 32-bit numeric address (IPv4) is written in decimal as four numbers separated by periods. ... IPv6 addresses are 128-bit IP address written in hexadecimal and separated by colons.How many IP versions are there?
