Pv6 Address Types

The IPv6 Address Space

As we already learned, IPv6 addresses are 128-bit long, which means that there are 340 undecillion possible addresses (the exact number is shown below).

340,282,366,920,938,463,463,374,607,431,768,211,456

or reference, in IPv4 with its 32-bit address space, there are 4.29 billion possible addresses.

The Internet Assigned Numbers Authority (IANA) allocates only a small portion of the whole IPv6 space. IANA provides global unicast addresses that start with leading leftmost bits 001. A small portion of the addresses starting with 000 and 111 are allocated for special types. All other possible addresses are reserved for future use and are currently not being allocated.
