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 invented in the 1970s. It was the first major version of Internet Protocol based on the 32 bit architecture. IPV4 allows numbers to map to physical devices and 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]
