		<description><![CDATA[One year on from the World IPv6 Launch in June 2012, we wanted to see how much progress has been made towards the goal of global IPv6 deployment. Both APNIC and Google are carrying out measurements at the end user level, which show that around 1.29% (APNIC) and 1.48% (Google) of end users are capable of accessing the IPv6 Internet. Measurements taken from this time last year show 0.49% (APNIC) and 0.72% (Google), which means the amount of IPv6-enabled end users has more than doubled in the past 12 months. <a href="https://circleid.com/posts20130606_one_year_later_whos_doing_what_with_ipv6">More...</a>]]></description>

		<title> Networks Announcing IPv6 Over Time: A Short Update (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/posts20130405_networks_announcing_ipv6_over_time_a_short_update</guid>
		<link>https://circleid.com/posts20130405_networks_announcing_ipv6_over_time_a_short_update</link>
		<description><![CDATA[We regularly check the status of IPv6 deployment in the RIPE NCC service region, and in other service regions as well. One way to measure IPv6 deployment is to look at the percentage of networks announcing IPv6 prefixes and follow the developments over time. The RIPE NCC's IPv6-ASN graph shows the percentage of networks that announce one or more IPv6 prefixes in the global routing system. Having an IPv6 prefix visible in the global routing system is a required step for a network to actually start exchanging IPv6 traffic with other networks. <a href="https://circleid.com/posts20130405_networks_announcing_ipv6_over_time_a_short_update">More...</a>]]></description>

		<title> 1,000th /22 Allocated from Last /8 (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/posts20130207_1000th_22_allocated_from_last_8</guid>
		<link>https://circleid.com/posts20130207_1000th_22_allocated_from_last_8</link>
		<description><![CDATA[On 14 September 2012, the RIPE NCC began allocating IPv4 address space from the last /8 we received from the Internet Assigned Numbers Authority (IANA). Nobody was entirely sure what would happen when we reached this point. Would there be a "run on the bank" for this final block of addresses? <a href="https://circleid.com/posts20130207_1000th_22_allocated_from_last_8">More...</a>]]></description>

		<title> A Look at How the Internet Routes Around Damage: Measuring Global Effects of Storm Sandy (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/posts20121115_a_look_at_how_internet_routes_around_damage_storm_sandy_effects</guid>
		<link>https://circleid.com/posts20121115_a_look_at_how_internet_routes_around_damage_storm_sandy_effects</link>
		<description><![CDATA[Hurricane Sandy caused major damage in both the Caribbean and the North-Eastern part of the USA. In an earlier article (RIPE Atlas - Superstorm Sandy) we showed data on 15 RIPE Atlas probes that are located in or near the affected areas in the USA. Most of these locations now appear to be back to normal round trip times to targets we monitor. But the effects of Hurricane Sandy were felt beyond the immediately affected area. <a href="https://circleid.com/posts20121115_a_look_at_how_internet_routes_around_damage_storm_sandy_effects">More...</a>]]></description>

		<title> New LIRs and Their IPv6 RIPEness (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/posts20121015_new_lirs_and_their_ipv6_ripeness</guid>
		<link>https://circleid.com/posts20121015_new_lirs_and_their_ipv6_ripeness</link>
		<description><![CDATA[The RIPE NCC's membership grew steadily over the course of 2012. In Q3, the RIPE NCC received 417 requests to become a Local Internet Registry (LIR); the highest number we have seen so far. This surge in membership growth exceeds the previous record set 12 years ago during the dotcom bubble in 2000. One reason for the surge is probably the anticipation of the last /8 of IPv4 addresses. <a href="https://circleid.com/posts20121015_new_lirs_and_their_ipv6_ripeness">More...</a>]]></description>

		<title> RIPE NCC is Reaching the Last /8 of IPv4 (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/posts20120918_ripe_ncc_is_reaching_the_last_8_of_ipv4</guid>
		<link>https://circleid.com/posts20120918_ripe_ncc_is_reaching_the_last_8_of_ipv4</link>
		<description><![CDATA[In an earlier article, IPv4 - Business As Usual, we pointed out that the RIPE NCC will reach the last /8 of IPv4 address space (16,777,216 addresses) sometime later this year. On Friday, 14 September 2012 we reached this important milestone; we allocated the last IPv4 addresses from the unallocated pool. From now on, the RIPE NCC can only distribute IPv6 addresses and a one-time /22 IPv4 allocation from the last /8 to those Local Internet Registries (LIRs) that meet the requirements. <a href="https://circleid.com/posts20120918_ripe_ncc_is_reaching_the_last_8_of_ipv4">More...</a>]]></description>

		<title> Update on AS Path Lengths Over Time - How Interconnected is the Internet? (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/posts20120910_as_path_lengths_how_interconnected_is_the_internet</guid>
		<link>https://circleid.com/posts20120910_as_path_lengths_how_interconnected_is_the_internet</link>
		<description><![CDATA[With the number of ASes connected to the Internet constantly increasing, one could expect that the length of the AS paths would also increase as the network as a whole gets wider. However, this doesn't seem to be the case. Also, with IPv6 being more widely deployed, how does the interconnectedness of the IPv6 portion of the Internet compare to IPv4? <a href="https://circleid.com/posts20120910_as_path_lengths_how_interconnected_is_the_internet">More...</a>]]></description>

		<title> Update on Assigning 32-bit ASNs (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/posts20120709_update_on_assigning_32_bit_asns</guid>
		<link>https://circleid.com/posts20120709_update_on_assigning_32_bit_asns</link>
		<description><![CDATA[As mentioned in Assigning 32-bit ASNs published one year ago, 16-bit Autonomous System Numbers (ASNs) are becoming a scarce resource just like 32-bit IP addresses. In 2007, the Internet Engineering Task Force (IETF) addressed this scarcity by developing a new format: 32-bit AS Numbers (RFC 4893), which increased the supply of ASNs to four billion. <a href="https://circleid.com/posts20120709_update_on_assigning_32_bit_asns">More...</a>]]></description>

		<link>https://circleid.com/posts20120625_measuring_world_ipv6_launch_comparing_ipv4_and_ipv6_performance</link>
		<description><![CDATA[Following on from last year's measurements after World IPv6 Day, the RIPE NCC carried out active measurements on World IPv6 Launch on 6 June 2012. These measurements included latency measurements both on IPv4 and IPv6 from our vantage points to selected hostnames of World IPv6 Launch participants and other dual-stacked parties. We used these measurements to determine the performance of IPv4 versus IPv6 connections. <a href="https://circleid.com/posts20120625_measuring_world_ipv6_launch_comparing_ipv4_and_ipv6_performance">More...</a>]]></description>

		<link>https://circleid.com/posts20120611_measurement_results_from_world_ipv6_launch</link>
		<description><![CDATA[As announced on RIPE Labs we monitored the behaviour of a number of networks that participated in the World IPv6 Launch on 6 June 2012. For that, we looked at the full list of participating organisations as shown on the ISOC website and chose 50 websites from that list. We looked at 'interesting' sites and at geographic distribution. We also tried to find a good mix of networks that had IPv6 switched on already and those that didn't have IPv6 deployed at the time they registered on the ISOC web site. <a href="https://circleid.com/posts20120611_measurement_results_from_world_ipv6_launch">More...</a>]]></description>

		<link>https://circleid.com/posts6607_measuring_ipv6_at_the_network_and_the_customer_level</link>
		<description><![CDATA[George Michaelson, APNIC's Senior Research and Development Scientist recently visited the RIPE NCC to collaborate on various research projects with his RIR colleagues. IPv6 measurements were one of the topics we looked at. Recent IPv6 statistics from the RIPE NCC show an accelerated uptake of IPv6 in Norway, both in terms of the number of allocated prefixes, and visible announcements in the routing system. <a href="https://circleid.com/posts6607_measuring_ipv6_at_the_network_and_the_customer_level">More...</a>]]></description>

		<description><![CDATA[At the recent RIPE Meeting we presented some IPv6 address distribution statistics that we would like to share with a wider audience. In the article below, you can find recent statistics on IPv6 allocations and assignments. The first image shows the number of IPv6 allocations the RIPE NCC made to LIRs in each quarter, starting in 2008... Each year is depicted in a different colour, the last one showing the number of allocations made in Q3 2012. <a href="https://circleid.com/posts20120501_update_on_ipv6_address_distribution_in_the_ripe_ncc_service_region">More...</a>]]></description>

		<link>https://circleid.com/posts20120416_what_ever_happened_to_the_closed_local_internet_registries</link>
		<description><![CDATA[Since the establishment of the RIPE NCC, 5,000 Local Internet Registries (LIRs) have closed. We wanted to find out why. Many of them were probably victims of the burst of the dotcom bubble. But how many? And which countries were mostly affected? How many closures were the results of mergers? We've got answers. <a href="https://circleid.com/posts20120416_what_ever_happened_to_the_closed_local_internet_registries">More...</a>]]></description>

		<description><![CDATA[The RIPE NCC is 20 years old and it now has over 8,000 members. In this article we are looking at the growth curve and the composition of the membership: what industry do RIPE NCC members come from today. The RIPE NCC became the first Regional Internet Registry in September 1992 (six months after it was set up as the secretariat for the European operators community, RIPE). <a href="https://circleid.com/posts20120403_from_80_to_8000_the_growth_of_the_ripe_ncc_membership">More...</a>]]></description>

		<title> Growth in IPv6-Capable DNS Infrastructure (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/posts20120319_growth_in_ipv6_capable_dns_infrastructure</guid>
		<link>https://circleid.com/posts20120319_growth_in_ipv6_capable_dns_infrastructure</link>
		<description><![CDATA[In our last post on CircleID we showed encouraging growth in the number of IPv6-enabled networks. But announcing an IPv6 prefix is only one of the first steps a network operator should take when deploying IPv6. For a full IPv6 deployment, IPv6 needs to be enabled on network infrastructure and made available to end users. One key piece of infrastructure for which we can measure IPv6 capabilities are DNS resolvers. <a href="https://circleid.com/posts20120319_growth_in_ipv6_capable_dns_infrastructure">More...</a>]]></description>
