Business Case for IPv6 - Part 2

In my previous blog on the topic, I stated that the business case supporting the IPv4 roll-out in the late 90s was the Internet. Although IP depletion will slowly become a reality, the chances are that due to mitigating technologies such as NAT and DNS64, it may take quite a while before organizations in the developed economies will get serious about IPv6. So where should we look to find a business case for IPv6? 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»

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»

How Accurate is the Routing Registry?

The Internet Routing Registry (IRR) is a globally distributed routing information database that consists of several databases run by various organisations. Network operators use the IRR to publish their routing policies and routing announcements in a way that allows other network operators to make use of the data. In addition to making Internet topology visible, the IRR is used by network operators to look up peering agreements, determine optimal policies and to configure their routers. more»

A Look at Nine Years of RIPE Database Objects: IPv6 Objects on the Rise

The RIPE Database is about to enter its fourth decade. It began humbly as a place to store network and contact information back when the RIPE community formed in 1989. When the RIPE Network Coordination Centre (NCC) was created three years later and started to assign and allocated IP address space, the database was expanded to include the registration of more detailed network and routing information. more»

IPv6… The Dangers of Prolonged Inter AS Tunnel Vision

Tunnel vision is a rather serious medical condition and the Internet or at least a number of service providers could be at risk if not treated soon enough. Symptoms of inter AS (Autonomous System) tunnel vision are many slower connections with IPv6 compared to IPv4 with some failing all together. Reason is that tunnels, especially inter-AS tunnels, can lead to long paths and non-optimal routing. more»

Most IT Professionals See No Compelling Benefits to IPv6, Says New Survey

Only 16% of IT professionals consider IPv4 address depletion "a huge concern that has or will soon force us to migrate to IPv6," according to a BT INS survey of 310 IT professionals that was conducted in December 2007. A whopping 26% of IT professionals felt IPv4 address depletion was "no concern.'' more»

A Closer Look at World IPv6 Day

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»

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»

NTIA Request for Comments on the Internet Assigned Numbers Authority (IANA) Functions

On Feb. 25, 2011, the National Telecommunications and Information Administration released the following request for comments concerning the USG's contract for the IANA function. As indicated, the USG's contract for the IANA function with ICANN expires later this year. Interested parties can file comments with NTIA by March 31, 2011. more»

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. 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»

What is 'On-Tap' at ICANN 38 - Brussels (There's More to Belgium than Beer!)

As the shorter of the ICANN interregnums comes to a close and the ICANN faithful finalize their dinner reservation agendas for Brussels, it is time again for a preview of what will be 'on-tap' at next week's ICANN meeting. While, as always, there is a lot going on in ICANN Land, a scan of the blogosphere and ICANN list serves suggests that the four most discussed topics will be... more»

Feds Ready for IPv6 D-Day

On June 30, U.S. federal government officials expect to declare an early victory on the IPv6 front. But they admit that meeting their much-heralded June 30 deadline for IPv6 compatibility is just the opening salvo of a long-term battle to get their networks ready for the Internet of the future. Under a White House policy issued in August 2005, all federal agencies must demonstrate the ability to pass IPv6 packets across their backbone networks by this deadline. more»

How Complete is the RIPE Routing Registry?

The Internet Routing Registry (IRR) is a globally distributed routing information database. The IRR consists of several databases run by various organisations in which network operators can publish their routing policies and their routing announcements in a way that allows other network operators to make use of the data. In addition to making Internet topology visible, the IRR is used by network operators to look up peering agreements, determine optimal policies and, more recently, to configure their routers. more»
