Today's ARIN estimated depletion date:


This is a new version of the dashboard, with some gauges removed and some added. If you liked the old dashboard better, please go to the old dashboard

Combined Burnrate The combined rate that we consume IPv4 addresses in the world over the last 30 days. The higher this gauge goes, the earlier we will reach depletion. The gauge is normalized so that the middle equals the burn rate that my other calculations are using. Combined Poolsize The combined size of free addresses that all the regional registrars has in their free pool. The pool size is expected to slowly grow as demand grows. The gauge is normalized so that the middle equals about the average pool size we have seen the last year.
IANA depletion date The IANA depletion date and how many days until we reach it. It is recommended that you are capable of IPv6 when the IANA pool runs out. First RIR depletion date The first RIR depletion data and how many days until we reach it. It is strongly recommended that all your systems are IPv6 capable at this date. Consider this the final warning.
Last RIR depletion date The last RIR depletion date and how many days until we reach it. It is mandatory that you are ready with your migration to IPv6 at this day as there will be no more IPv4 addresses. Many regular and Small Business Web Hosting providers have already started working on a full switch over to IPv6. First RIR to be depleted The first region that will run out of IPv4 addresses. However, the difference between the first and last region is only a few months. The date when the first region will run out is visualized in the gauge above.

Total free IPv4 The total number of free IPv4 addresses in all pools held by IANA and the five regions. (various pool + the 5 RIR + IANA). This will be 0 at last RIR depletion date.

TLD with IPv6
Percentage of Top Level Domains with IPv6 enabled. As you can see, the TLDs has done a good job migrating to IPv6. (Data from
TLD with v6 Glue Percentage of Top Level Domains with DNS glue records. Doesn’t really say that much about IPv6 adoption, but can perhaps be used as a metric on how easy it is to find IPv6 connectivity outside of the developed contries. Will always be lower or equal to the TLD with IPv6. (Data from
AS with IPv6 Autonomous system with IPv6. Could be interpreted as how many of the big guys that have some kind of IPv6 network in production. (Data from Reverse IPv6 DNS What percentage of the reverse DNS servers for IPv6 are reachable over IPv6. How many eat their own dogfood? (Data from
IPv6tf sites over IPv6 How many of the site found at are accessible over IPv6. (Data from Alexa with IPv6 How many of the top 500 ranked alexa sites are accessible over IPv6. You can interpret this as how many of the busiest websites in the world are giving the visitor a choice to connect to the site over IPv6. Google for example, choose another method and are only serving AAAA records to networks that pre registered with them. (Data from
