About My IPv6

This site shows whether you are connecting via IPv4 or IPv6.

An IPv6 address, which stands for Internet Protocol version 6, is the most recent version of the internet protocol used to identify and locate devices on the internet. IPv6 was developed to address various shortcomings of its predecessor, IPv4, primarily the shortage of available IP addresses. This is crucial as the number of devices connecting to the internet grows.

Unlike IPv4, which uses a 32-bit address structure and can contain about 4.3 billion unique addresses, IPv6 uses a 128-bit address structure. This leads to an almost inexhaustible supply of addresses, an astronomical amount of about 340 undecillion possible addresses. This expansion ensures that every conceivable future device, from smartphones to refrigerators, can have a unique IP address.

IPv6 addresses are typically noted as eight groups of four hexadecimal digits, separated by colons. For example: 2001:0db8:85a3:0000:0000:8a2e:0370:7334. Within this notation, compression techniques are allowed that can simplify the display of IPv6 addresses, such as omitting leading zeros and merging consecutive sections of zeros.

The rollout of IPv6 is an important step in future-proofing the internet, as it supports more devices, better routing and address autoconfiguration, as well as improvements in security. Thus, IPv6 has become a crucial foundation for the ongoing growth and development of the internet.
