The next version of the TCP/IP protocol, IPv6 offers 128-bit address space, or 2 128 (≈ 3.4 x 10 38) IP addresses this is approximately 5×10 28 addresses for each of the roughly 6.5 billion people alive today, or about 57 billion addresses for each gram of matter in the Earth, or 6.67*10 23 addresses for each m² of Earth, including oceans. There are too many devices in the world for 32-bit (2 32, or 4,294,967,296) IP addresses to be sufficient. It follows IPv4 as the second version of the Internet Protocol to be formally adopted for general use. Internet Protocol version 6 ( IPv6) is a network layer IP standard used by electronic devices to exchange data across a packet-switched network.
