IPv6 Guide: Next Generation IP Addressing

IPv6 (Internet Protocol version 6) is the most recent version of the Internet Protocol, designed to replace IPv4 and solve the address exhaustion problem. With 128-bit addresses supporting 340 undecillion unique addresses, IPv6 is the future of internet connectivity.
