   Description

 The allocation of Internet Protocol version 6 (IPv4) unicast address space is listed
 here. References to the various other registries detailing the use of the IPv6 address
 space can be found in the IPv6 Address Space registry [IANA registry ipv6-address-space].

   Note

 The assignable Global Unicast Address space is defined
 in [RFC4291] as being the address block defined by the
 prefix 2000::/3. All address space in this block not
 listed in the table below is reserved by IANA for
 future allocation.

   This registry is also available in XML and plain text formats.
