IPv6 Transition

IPv4 Historical Imbalances and the Threat to IPv6

It is an open secret that the current state of IPv4 allocation contains many accidental historical imbalances and in particular developing countries who wish to use IPv4 are disadvantaged by the lack of addresses available through ordinary allocation and are forced into purchasing addresses on the open market. As most of the addresses for sale are held by organisations based in the developed world, this amounts to a transfer of wealth from the developing world to the developed world, on terms set by the developed world.

How a New gTLD Should Choose a Back-end Registry System - Part 3

This part 3 of the selecting a back-end registry service provider series focuses on Whois and sharing data in new gTLDs. If you've ever looked up information about a domain name you've used a Whois service. It's the public information system about contact information for a domain name or IP addresses, though in this article, we will just talk about domain name Whois. In some generic and sponsored Top Level Domains (gTLDs), Whois is run authoritatively by the gTLD. In older gTLDs such as .com and .net, the authoritative Whois service is run by the registrar responsible for the domain name. While some TLD operators run their own infrastructure...

Visibility of Prefix Lengths in IPv4 and IPv6

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.

IPv6 Transitional Uncertainties

The telecommunications industry has been around for quite some time. Whether you take it as a starting date the first efforts with the wired telegraph in the 1830's, or the telephone in the 1870's, this industry has been around for quite a long time. During this periods it has made huge achievements, and there is no doubt that the impacts of this industry have changed our lives in many ways... It is literally amazing that this industry has managed to preserve dial tone on telephone handsets while completely changing the underlying network and switching fabric of the telephone system numerous times.

The Rising Technical Challenges of Networking at Home

For me, one of the more interesting sessions at the recent IETF 81 meeting in July was the first meeting of the recently established Homenet Working Group. What's so interesting about networking the home? Well, if you regard challenges as "interesting", then just about everything is interesting when you look at networking in the home!

Comparing IPv4 and IPv6 Performance

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.

Assigning 32-bit ASNs

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.

The Future of the Internet Economy: Chapter 2

The OECD held a "high-level" meeting in June 2011 that was intended to build upon the OECD Ministerial on The Future of the Internet Economy held in Seoul, Korea in June 2008. I was invited to attend this meeting as part of the delegation from the Internet Technical Advisory Committee (ITAC), and here I'd like to share my impressions of this meeting. This 2 day meeting, "The Internet Economy: Generating Innovation and Growth", had the objective of exploring a number of current issues in the public policy space...

IPv6 Enabled Networks Before and After World IPv6 Day

In our last post on CircleID, Measuring World IPv6 Day - First Impressions, we showed exactly when World IPv6 Day participants switched on IPv6 on their networks (by way of announcing DNS AAAA records). Now, a few weeks after World IPv6 Day, it's interesting to see what the longer-term effects have been.

Beyond Limitations and What Good It Would Do to ICANN to Operate from Abundance

The ICANN community is conservative. A considerable number of dedicated ICANN volunteers from various constituencies believe that ICANN should follow the unusual logic of limiting its revenues to the levels of its CURRENT estimates of expenditure. The Board, acting on the advise of the ICANN community brought down the ICANN transaction fee per domain name from 25 cents to 16 cents and in the case of numbers, for various reasons the Address Registry fees that it collects from the Regional Internet Registries have been historically kept at a negligibly low level.
