IPv6 distribution
IPv6 cumulative distribution (number of /32 delegated)
With the inevitable depletion of IPv4, the Internet community recognizes that the steady adoption of IPv6-based networks is important to ensure the future success of the Internet.
Delegations of IPv6 address space are showing increased levels of commitment from network operators to deploy IPv6 networks. The graph on this page shows a levelling of growth from the IPv6 address size point of view. This is a direct result of the policies to reduce the end-site assignment from /48 to /56, and the change of the HD ratio, where Members can obtain additional IPv6 addresses, from 0.8 to 0.94
