This year's ARIN transfers have already exceeded the total number of ARIN transfers in 2015; worldwide global native IPv6 connectivity tops 11%

Transfer Activity

In late 2015, Avenue4 shifted from tracking and reporting on number of IPv4 transfers (i.e., individual IPv4 block transfers reported by the RIRs) to the number of IPv4 transactions.  For purposes of our market reports, a single transaction represents a transfer of numbers (which may include multiple blocks) between the same parties either on the same day or within a very short timeframe.  We believe this view of the data is a more accurate reflection of IPv4 market activity – thus making last month’s data all the more significant.

In the first four months of 2016, the number of IPv4 transactions involving the ARIN region exceeded the total number of transactions for 2015.  Transactions based on Section 8.3 (specified transfers) alone exceeded 200, more than the number of transactions in all of 2015.  In addition, Section 8.4 InterRIR transfers during the first 4 months doubled between 2015 and 2016, attributable mostly to increased market activity between the ARIN and RIPE regions.

The substantial growth in volume of transactions in 2016 is not matched by a growth in volume of numbers transferred, however.  At this same time last year, ARIN’s transfer statistics reflected over 13 million total numbers transferred under Sections 8.3. and 8.4 of the ARIN NRPM.   To date in 2016, just under 4 million numbers have been transferred.

IPv6 Deployment

Worldwide global native IPv6 connectivity finally hit (and exceeded) 11% in April.  Weekday connectivity ranged around 9%.  There was a general uptick in IPv6 connectivity across several large telco companies globally, and the UK joined the “5% club” – i.e., the countries with IPv6 connectivity exceeding 5%, which thus far totals 21 countries worldwide.  According to the Vyncke analysis on IPv6 enabled browsers, worldwide, IPv6 enabled browsers are expected to reach 50% in September 2021 while the U.S. is expected to reach 100% deployment in January 2020 – no change from last month.


In the news, Geoff Huston undertook a detailed analysis of whether the Internet of Things could flourish absent a migration to IPv6, and Dyn Research issued its annual “Baker’s Dozen” report, measuring the top Internet providers for 2015.   For information on these issues and more, please see Avenue4’s resources page.
