Notes:

[0]  The assignable Global Unicast Address space is defined
     in [RFC3513] as being the address block defined by the
     prefix 2000::/3. All address space in this block not
     listed in the table above is reserved by IANA for
     future allocation.

[1]  IANA Special Purpose Address Block [RFC4773].
     See: http://www.iana.org/assignments/iana-ipv6-special-registry

[2]  2001:0DB8::/32 has been assigned as a NON-ROUTABLE
     range to be used for documentation purpose [RFC3849].

[3]  2001:3C00::/22 is reserved for possible future allocation
     to the RIPE NCC.

[4]  2002::/16 is reserved for use in 6to4 deployments [RFC3056].
