#1, History of the IP address Добавить связанный Изменить Удалить

IP addresses evolved with the internet, from a small research network into the global system that connects billions of devices.

A shared way to find computers

Early packet networks connected only a few research computers. When independent networks started communicating, they needed a common way to name destinations and move data between them.

The Internet Protocol provided that common language. An IP address became the routing label that helps network equipment forward a packet towards the right network and device.

IPv4 connected a growing internet

IPv4 became the standard in the early 1980s. It uses 32-bit addresses, usually written as four decimal groups, such as 203.0.113.10.

About 4.3 billion possible addresses seemed generous at first, but personal computers, smartphones, home routers, and connected equipment made the supply limited.

NAT and the move to IPv6

Private address ranges and network address translation (NAT) let many devices share one public IPv4 address. This conserves addresses but can complicate direct incoming connections.

IPv6 uses 128-bit addresses and offers a vastly larger space. IPv4 and IPv6 commonly operate together while the transition continues.
