Number of IPv6 Addresses
How many IPv6 addresses are there?
The latest version of the Internet Protocol ‘â€œ Internet Protocol version 6 (IPv6) ‘â€œ was established in 1998 with a view to supplanting IPv4. Whereas IPv4 uses 32-bit addresses, IPv6 uses 128-bit addresses, which dramatically broadens the range of address availability: from 232 (about 4 billion)to 2128 addresses (or 3.4 x 1038). The adoption of IPv6, however, is still at an early stage: less than 5% of internet connections.
