IANA Up For Grabs?

The US government wants to hear from organizations interested in running some of the internet's key resources, including the master lists of IP address space and domain names.

The Department of Commerce last week published a request for information, a step before potentially putting a contract out to bidding, soliciting interest from anybody interested in taking over the Internet Assigned Numbers Authority. more»

What Digital Divide on IP Addresses?

I took an instant dislike to The Digital Divide on IP Addresses post for some reason, well for many reasons actually. First and foremost is that the implication that the "digital divide" is somehow caused by IP address allocation policies. While it is certainly true that there are "digital divides" between developed and developing parts of the world, the historical imbalance in IP addressing is not one of them. The fact is that while we will "run out" of IPv4 addresses at some point in the not too distant future, there are an unimaginably large number of IPv6 addresses available. more»

Network Complexity: Three Trends That are Contributing to a "Perfect Storm"

Most everyone who visits CircleID is familiar with Moore's Law, which stated simply holds that computing power doubles every 18 months. This has been going on since the 1960s and shows no sign of slowing. Moore's Law drives faster and faster computing, which produces more and more data and network complexity. This inexorable trend is putting immense pressure on corporate networks, and the strain is too much for many of them to handle on their own. more»

Announcement: Critical Internet Infrastructure WG is Now Open to Public Participation

ISOTF Critical Internet Infrastructure WG is now open to public participation. The group holds top experts on internet technology, critical infrastructure, and internet governance, from around the globe. Together, we discuss definitions, problems, challenges and solutions in securing and assuring the reliability of the global internet infrastructure, which is critical infrastructure for a growing number of nations, corporations and indeed, individuals -- world wide. more»

IPv6… the Internet Dragon Stirred Under Its Shell

At Cisco Networkers in Barcelona earlier this week, some of us saw a dragon try to wiggle out of its shell, provided you connected in IPv6 that is. A smile to Kame, the turtle which only danced under a IPv6 caress. Networkers 2009 saw more than 3000 attendants and a good complement of IPv6 presentations highlighted by a high powered plenary panel on the status of IPv6. more»

Measurement Results from World IPv6 Launch

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. more»

Painting Ourselves Into a Corner with Path MTU Discovery

In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more»

ARIN Launches WHOWAS: Trial Service Providing Historical Information for a Given IP Address

American Registry for Internet Numbers (ARIN) is running a trial service that gives users access to historical IP whois data – that is, it will tell you who was responsible for an IP address or block of IPs. The service is not automated and if you want to access it you will need to submit a request via email with information about not only what you want to know, but why you are interested in accessing the information. more»

Some Internet Measurements

At APNIC Labs we've been working on developing a new approach to navigating through some of our data sets the describe aspects of IPv6 deployment, the use of DNSSEC and some measurements relating to the current state of BGP. The intent of this particular set of data collections is to allow the data to be placed into a relative context, displaying comparison of the individual measurements at a level of geographic regions, individual countries, and individual networks. more»

IP Address Distribution Doesn't Fit in the Registry/Registrar Model

At the IGF2010 in Vilnius, two folk are floating a trial balloon about separating the allocation function from the registry services function. Currently, these functions are seen as indivisible by the Internet addressing community. In other words, one gets an allocation or assignment from a RIR and the RIR adds the assignment to their database... The question being asked is "Is it time for a split between allocation and services for Internet number resources as was the case for domain name resources?" My answer is no more»

IANA: The World Loses if the Technical Industry Checks Out

On Friday, 14 March 2014, the U.S. Department of Commerce National Telecommunications and Information Administration (NTIA) announced its intention to transition the IANA functions to the global multistakeholder community. As expected, the announcement has sent adrenaline coursing through the veins of Internet governance experts and government policy people the world over. I'd argue, however, that it is an important point for the Internet's technical experts to sit up and take notice, as well: the fact that you are probably saying "what problem does this solve?" is a testimony to how much works well today, and we want to make sure it continues to work well in any future arrangements. more»

Business Case for IPv6 - Part 1

When discussing IPv6, it is easy to forget that we are ultimately talking about an enhanced version of an existing network protocol. Sure, it brings about a number of technical advantages. But when viewed in isolation - without a business case - there really are not that many drivers that would place IPv6 on the agenda of the top decision makers looking after budgets. For IPv6 to gain serious momentum, this has to be changed. more»

ICANN Chairman's Durban Roundup

Respected ICANN Chairman of the Board Steve Crocker has wrapped up his organisation's 47th International Meeting, held in Durban last week, with a message to the community. This message, reproduced here in its entirety, provides both a useful and concise summary of the Durban meeting and insights into the Chairman's view of where ICANN stands at the moment, the successes it has notched up and the challenges it faces. more»

The ISP Industry and the Financial Sector - Amazing Similarities

In the last RIPE Labs article on this subject How Does the Internet Industry Compare?, we looked at ways to compare our industry with other industrial sectors, and identified a number of characteristics that an industry must have in order to be comparable to the Internet industry. It seems the financial sector or monetary credit industry shares many of these characteristics and in fact behaves much like the Internet industry. more»

Do We Need An IPv6 Flag Day?

In recent interviews about World IPv6 Launch I've been asked by several different people whether or not I think there needs to be some kind of a "Flag Day" on which the world all together switches from Internet Protocol version 4 (IPv4) to the version 6 (IPv6). I don't think a flag day is needed. World IPv6 Launch is just the right thing. It's worth looking at some previous flag-type days to get a better sense of why. more»
