What is an IPv6 Address
The greatest benefit of IPv6 addressing over the previous used IPv4 addressing is the enormous addressing space that contains.
IPv6 supports 128 bit addressing space and can potentially support 2 ^ 128 or 3.4 x 10 ^ 38 unique IP addresses (as opposed to 32 bit addressing space of IPv4). With this enormous addressing space scheme, IPv6 can provide unique addresses to each and every device attached to the Internet.
