IPv6 Consumption

This analysis examines the rate of consumption of the IPv6 address space allocated by IANA to the RIRs and ultimately to end users.

IPv6 Address Space Assignments to RIRs

Although IPv6 allocations have occurred sporadically over the past 6 years, an overwhelming majority (92.5%) of the allocations, in terms of address space coverage, have been made in a surge in the recent 15 months (from May 2004 to the end of the studied period; see Figure 1). This recent acceleration in growth suggests increasing interest in IPv6.

RIPE and APNIC hold the majority (91.2%) of the allocations, with RIPE holding 48.3% of the total 75,264 /32's and APNIC holding 42.9%. ARIN holds 8.2%, and LACNIC holds less than 1% in a single /23 allocation, which is equivalent to 512 /32's, allocated on Nov 1, 2002.
