20,000 Local Internet Registries - A Peek into the Future by Rene Wilhelm — last modified 04 Oct, 2018 01:10 PM

On 25 September 2018, the RIPE NCC passed the milestone of 20,000 Local Internet Registries (LIRs). We look at what's happened since the previous milestone of 15,000 LIRs and share our thoughts about the future: how much time is left for the IPv4 pool, and what are the prospects for membership developments?

RIPE NCC Membership - Developments After Reaching the Last /8 by Rene Wilhelm — last modified 06 Jun, 2018 11:09 AM

On 14 September 2012, the RIPE NCC started allocating IPv4 addresses based on the last /8 policy. With more than two years passed, we look at the effects this had on membership numbers and demographics. We also look at what the last /8 policy meant for IPv6 uptake.

So Long Last /8 and Thanks For All the Allocations by Rene Wilhelm — last modified 21 Mar, 2019 10:17 AM

On 17 April 2018, we allocated the last available block of 1,024 addresses in 185/8 - the last /8 we received from IANA back in 2011. This article looks at how this address space was allocated and how it is used today. It's important to keep in mind that while 185/8 is finished, we still have around nine million recovered IPv4 addresses in our available pool. Under current policy and growth rates, we expect these to last a further two years.

15,000 Local Internet Registries by Rene Wilhelm — last modified 17 Apr, 2018 11:01 AM

On 28 December 2016, about 90 days before its 25th anniversary, the RIPE NCC reached the milestone of serving 15,000 active Local Internet Registries (LIRs). In this article we look at trends observed in the membership in the last few years. We also assess the remaining lifetime of the last bit of IPv4 in our available pool.

RIPE NCC Members and Resources in 2017 by Rene Wilhelm — last modified 12 Feb, 2018 09:45 AM

In this article we're looking at membership developments over the previous year. How many new LIRs opened, and is this consistent with our earlier projections? How much longer will IPv4 last? And what about IPv6 uptake?

A Shrinking Pie? The IPv4 Transfer Market in 2017 by Rene Wilhelm — last modified 31 Jan, 2018 09:49 AM

A record number of IPv4 addresses were transferred between LIRs in the RIPE NCC service region in 2017. However, 16 of the largest transfers, amounting to 78% of the total transferred address space, were really about the administrative management of resources between related business units. In terms of buyers and sellers, this part of the IPv4 transfer market decreased in size last year.

RIPE NCC Membership Statistics Q3 2015 by Rene Wilhelm — last modified 24 Jan, 2018 09:21 AM

We look at the RIPE NCC in terms of growth, geographic distribution and IPv6 deployment. We find that recent RIPE policy changes have had an impact on membership statistics and development trends.

IPv4 Transfers in the RIPE NCC Service Region by Rene Wilhelm — last modified 16 Oct, 2017 11:21 AM

Now that the RIPE NCC has reached its last /8, some Local Internet Registries (LIRs) are choosing to obtain additional address space from other organisations via the emerging transfer market. Here we examine statistics from the last two and a half years of transfers and visualise per country aggregates on a map.

Measuring your Web Server Reachability with TCP Ping by Rene Wilhelm — last modified 27 Sep, 2017 03:24 PM

HTTP measurements from RIPE Atlas probes are only possible towards RIPE Atlas anchors. However, when it comes to measuring the connectivity and latency of web servers on the network level, an alternative exists, which we call TCP Ping: a traceroute with special options that mimic the TCP handshake that takes place when an HTTP connection is established. In this article we compare the results of large scale HTTP and TCP Ping measurements.

Developments in IPv4 Transfers by Rene Wilhelm — last modified 31 Jul, 2017 10:48 AM

In May 2015, we looked at IPv4 transfers in the RIPE NCC service region and found signs of an emerging market. Both the number and size of transfers conducted under RIPE Policy showed an upward trend in the years 2013-2014. One year later, we take another look. Did this trend continue? What have been the effects of the inter-RIR transfer policy?

IPv6 RIPEness - Sorted by LIR's Age and Size by Rene Wilhelm — last modified 10 Jul, 2017 09:47 AM

Following up from the recently published IPv6 RIPEness update, we are now looking at the IPv6 RIPEness of Local Internet Registries relative to their age and relative to their size.

Trends in RIPE NCC Service Region IPv4 Transfers by Rene Wilhelm — last modified 29 Jun, 2017 12:23 PM

With only a few months left until the fifth anniversary of RIPE NCC reaching the last unallocated /8 of IPv4 space, we look at developments in transfers in, to and from the RIPE NCC service region.

IPv6 RIPEness Through the Years by Rene Wilhelm — last modified 13 Apr, 2017 09:10 AM

In 2010, we introduced IPv6 RIPEness to recognise Local Internet Registries (LIRs) in the RIPE NCC service region that had begun deploying IPv6. Seven years later, we looked at how the IPv6 RIPEness level of the RIPE NCC membership evolved over time.

RIPE NCC Membership - 2012 Statistics by Rene Wilhelm — last modified 09 Mar, 2017 01:24 PM

At the start of a new year and four months after we reached the last /8 of IPv4 address space, we looked at our membership statistics again. Have we seen an increase in members or resource requests?

IPv6 RIPEness in 2017 by Rene Wilhelm — last modified 13 Feb, 2017 10:27 AM

This post provides an update on our IPv6 RIPEness project, including an analysis of IPv6 RIPEness for new Local Internet Registries (LIRs).
