The number of RIPE NCC members [also referred to as Local Internet Registries (LIRs)] that have an IPv6 allocation continues to grow -- in absolute terms as well as in percentages. 46% of all RIPE NCC members have one or more IPv6 RIPEness stars. ... Do new members pick up IPv6? Are older members with more experience, well-established businesses and customer base dominating IPv6 RIPEness scores? And what about the size of a member? Are small and large members adopting IPv6 in equal proportions? In this article we look into answering these questions. more
Internet routes are specified for an address prefix. The shorter the prefix, the more general the route. A shorter prefix covers more address space and thus a bigger part of the Internet. Very long prefixes cover few addresses and are used for local routing close to the destination address. In general, it is not necessary to distribute very long prefixes to the whole Internet, because a more general, shorter prefix is sufficient to direct packets in the direction of the destination. more
Geoff Huston, APNIC's Chief Scientist, is visiting the RIPE NCC this week to spend time with his fellow Regional Internet Registries (RIR) colleagues and to strengthen collaboration on shared projects. We've used this opportunity to invite him to produce the 'Interesting Graph of the Week'. Geoff has been monitoring the global routing system for many years. Here are his most recent observations. more
Accurate registration data is essential for the global registry system. To ensure that the RIPE Registry's data is correct, up-to-date and accurate, the RIPE NCC regularly checks the Registry data to fix inconsistencies and outdated information. We recently evaluated and analysed all IP address ranges registered in the RIPE Database and were pleased to find that 96.09% of those records are considered accurate. more
Objects in the RIPE Database can only be modified by those authorised to do so. For instance, an object representing a certain range of IP addresses assigned to an organisation by the RIPE NCC or a Local Internet Registry (LIR) can be modified by the organisation holding that address space. Each database object contains one or more attributes referencing the maintainer(s) of that object. In a maintainer (MNTNER) object, credentials are listed for those who are authorised to modify any object referencing that MNTNER object. more
The active measurements the RIPE NCC carried out on World IPv6 Day on 8 June 2011 included ICMP (Internet Control Message Protocol) and ICMP6 (ICMP for IPv6) measurements from our vantage points to selected hostnames of World IPv6 Day participants and other dual-stacked parties. We used these measurements to determine the performance of IPv4 versus IPv6 connections. more
With 16-bit Autonomous System Numbers (ASNs), 65,536 unique numbers are possible. Just like 32-bit IP addresses, these 16-bit ASNs are becoming a scarce resource. Therefore, in 2007 the Internet Engineering Task Force (IETF) developed a new format, 32-bit ASNs (RFC 4893), which increases the supply of ASNs to four billion. more
The RIPE NCC took active measurements of World IPv6 Day participants before, during and after World IPv6 Day (in cooperation with CAIDA). We selected 53 participants and performed periodical A and AAAA DNS lookups and HTTP fetches from 40 servers worldwide. For HTTP, we fetched data over IPv4 and IPv6. These provide important control points... more
Feb. 3, 2011, came and went without much fanfare, but it was a milestone for Internet stakeholders, whether they knew it or not. On that Thursday, the last available IPv4 addresses were allocated by the Internet Assigned Numbers Authority (IANA). Though some Regional Internet Registries (RIRs) have a reasonable inventory of IP addresses that could last another year or two, the days of "new" IPv4 address allocations are largely over. more
In observance of World IPv6 Day being held today, Earl Zmijewski of Renesys takes a closer look at the state of the IPv6 today. Zmijewski writes: "Today is World IPv6 Day, a day when major content providers have agreed to furnish service over IPv6 for a 24-hour test period. Hopefully, you didn't notice anything different about your Internet experience today, but providers will have gained valuable experience with the technology and any technical hurdles that remain to be overcome..." more
Since IANA ran out of IPv4 addresses, people are increasingly aware of how short the remaining lifetime of IPv4 is. With World IPv6 Day taking place this week, the issue has come into even sharper focus. Since March 2011, the RIPE NCC has been publishing the size of its pool of available IPv4 addresses. All five Regional Internet Registries (RIRs) regularly publish the status of their IPv4 address pools. In the image below, you can see how the number of IPv4 addresses in the RIPE NCC pool changes over time. more
RIPE NCC has announced plans to conduct live measurements for World IPv6 Day on 8th June 2011. The not-for-profit organization has set to measure connectivity to World IPv6 Day participants; "the IPv6 Eye Chart tests visibility of all World IPv6 Day participants and other sites that are already dual-stacked on a single web page." RIPE NCC says the process will help to find out if there are problems accessing these websites, both before and during World IPv6 Day. more
The number of web-based devices is expanding at an exponential clip, virtualization is making a very static environment dynamic, and now with the exhaustion of IPv4 and the oncoming complexities of IPv6 network operators must reevaluate what IP Address Management (IPAM) really is. The goal of this post is to define the various functions that make up IP Address Management. more
This is the prepared opening statement given on behalf of Depository, Inc. at the panel discussion "IP addressing in the new age of scarcity" in the context of Internet governance and public policy at the Global Internet Governance: Research and Public Policy Challenges for the Next Decade Regional Conference held at the American University School of International Service on Thursday, May 5th, 2011 between 11:00 a.m. to 12:15 p.m. with Prof. Milton Mueller moderating and on the panel as well was John Curran, President and CEO of ARIN and Michael Froomkin, Professor of Law, University of Miami School of Law. more
A year ago, the RIPE NCC introduced IPv6 RIPEness -- a system that rates IPv6 deployment of Local Internet Registries (LIRs)... Now, one year later, the numbers have gone up... In absolute numbers: more than 3,000 LIRs have IPv6 address space. This means that the RIPE NCC has made more than 1,100 IPv6 allocations within 12 months. more
