Stands for “Internet Protocol version 6.”

IPv6 is the newest model of the Internet Protocol (IP). It supplies an identification and placement system for web-connected gadgets, assigning IP addresses to gadgets that assist network gear route visitors. IPv6 is step by step changing the earlier commonplace, IPv4, and resolves the issue of IPv4 handle exhaustion.

Every internet-connected device wants an IP handle for identification that different gadgets can use to ship it knowledge. IPv4 makes use of 32-bit addresses, which permits for nearly 4.3 billion distinctive addresses. While this was enough within the early days of the Internet, there are actually way more internet-connected gadgets than potential IPv4 addresses. IPv6 as an alternative makes use of 128-bit addresses, offering sufficient handle area for 340 undecillion (or 340 trillion trillion trillion) distinctive IP addresses — sufficient to be successfully limitless.

An IPv6 handle consists of 8 teams of 4 hexadecimal digits, which is longer and more complicated than an IPv4 handle. For instance, examine a easy IPv4 handle like to a more complicated IPv6 handle:


In addition to vastly rising the accessible handle area, IPv6 provides a number of different enhancements to the IP protocol. It consists of built-in help for IPsec safety and multicast knowledge flows (each non-obligatory options in IPv4). IPv6 makes use of a less complicated packet header to cut back processing overhead throughout routing. It additionally simplifies the auto-configuration of network addresses to make it simpler for gadgets to hitch networks. Finally, it reduces the necessity for NAT on native networks, which improves reliability for companies like VoIP telephony.

IPv6 Adoption

The rollout of IPv6 started within the mid-2000s as software program makers added help to working programs and network infrastructure. DNS server help started in some nations in 2004. By 2008 it was potential to resolve any domain title using IPv6, and several other massive corporations completely enabled IPv6 help on their internet servers in 2012. However, many networks nonetheless function using IPv4 because the adoption of IPv6 strikes at a gradual tempo; as of 2023, almost half of the visitors to Google makes use of IPv6, up from only one.5% a decade earlier.
