IPv4 (Internet Protocol version 4) is the version of Internet protocol that defines IP addresses in a 32-bit format which looks like which looks like 123.123.123.123. Each three-digit section can include a number from 0 to 255. The total number of IPv4 addresses available is approximately 4.2 billion,[1]
The available IP addresses is not enough to cope with projected Internet demand in the next 5-10 years.[2]
History
IPv4 was the first major version of Internet Protocol that allows numbers to map to physical devices and to build a logical method for traffic to route from one number to another. It was first introduced in 1981 when the Internet went live to the public.[3] IPV4 is the general standard to deliver information between devices connected to the Internet.[4]
