IPv6 network addresses
An Internet Protocol version 6 (IPv6) addressing technology - is another logical element that identifies a device on a computer network. The label v6 represents the sixth version of IP addressing, as specified in IETF publication RFC 2460.

The fact that IPv6 uses 128 bits makes it possible to use 2128 IPv6 addresses which when calculated gives an approximate number of 340 undecillion IPv6 addresses . Undoubtedly, that represents an extremely large number of available IPv6 addresses.
