Internet Protocol version 6
IPv6 is the next generation IP address standard intended to supplement and eventually replace IPv4, the original and ubiquitous IP address scheme. Every computer, mobile phone, home automation component, IoT sensor, and any other device connected to an IP-based network needs a numerical IP address to communicate with other devices.
Public reachable IPv4 addresses are in short supply due to their widespread usage and constantly increasing demand stemming from the proliferation of connected devices globally. The last available block of new IP version 4 (IPv4) addresses was allocated back in 2011, and from that time on, everyone has been reusing a finite set of available addresses. IP version 6 (IPv6) is the replacement for IPv4, and it is designed to address the depletion of IP addresses, and change the way traffic is managed.
