IPv4 Markets

IPv6: Penny Wise and Pound Foolish

The theory put forward by the IETF was simple enough... while there were still enough IPv4 addresses, use transition technologies to migrate to dual stack and then wean IPv4 off over time. All nice and tidy. The way engineers, myself included, liked it. However those controlling the purse strings had a different idea.

A Royal Opinion on Carrier Grade NATs

There are still a number of countries who have Queen Elizabeth as their titular head of state. My country, Australia, is one of those countries. It's difficult to understand what exactly her role is these days in the context of Australian governmental matters, and I suspect even in the United Kingdom many folk share my constitutional uncertainty... In the United Kingdom every year the Queen reads a speech prepared by the government of the day, which details the legislative measures that are being proposed by the government for the coming year. Earlier this month the Queen's speech included the following statement in her speech.

Can’t Sell Your IPv4 Numbers? Try Leasing Them

In a "policy implementation and experience report" presented at ARIN 31 in Barbados, ARIN's staff noted that they are seeing "circumstances" related to the leasing of IPv4 number blocks. At the recent INET in Denver, ARIN's Director John Curran alleged that there is a "correlation" between address leasing activity and organizations that have been unable to complete specified transfers through the ARIN process, which requires needs-based justification.

A Primer on IPv4, IPv6 and Transition

There is something badly broken in today's Internet. At first blush that may sound like a contradiction in terms. After all, the Internet is a modern day technical marvel. In just a couple of decades the Internet has not only transformed the global communications sector, but its reach has extended far further into our society, and it has fundamentally changed the way we do business, the nature of entertainment, the way we buy and sell, and even the structures of government and their engagement with citizens. In many ways the Internet has had a transformative effect on our society that is similar in scale and scope to that of the industrial revolution in the 19th century. How could it possibly be that this prodigious technology of the Internet is "badly broken?"

Correlation Between Country Governance Regimes & Reputation of Their Internet Address Allocations

We recently analyzed the reputation of a country's Internet (IPv4) addresses by examining the number of blacklisted IPv4 addresses that geolocate to a given country. We compared this indicator with two qualitative measures of each country's governance. We hypothesized that countries with more transparent, democratic governmental institutions would harbor a smaller fraction of misbehaving (blacklisted) hosts. The available data confirms this hypothesis. A similar correlation exists between perceived corruption and fraction of blacklisted IP addresses.

Live Today - “IPv4 Exhaustion and the Path to IPv6” from INET Denver

If you are interested in the current state of IPv4 address exhaustion within North America as well as the current state of IPv6 deployment, there will be a live stream today, April 17, of the sessions happening at INET Denver starting at 1:00pm US Mountain Daylight Time (UTC-6). The event is subtitled "IPv4 Exhaustion and the Path to IPv6" and you can view the live stream at.

What’s the Best IPv6 Transition Option for You?

After decades of talk, the time for IPv6 has finally arrived. There are several transition options available, but whatever approach you choose, the challenge will be to make sure that your subscribers don't experience a reduction in quality of service. IPv4 is likely to co-exist with IPv6 for some time, so a native dual-stack migration strategy will be the best transition option for most providers... With dual-stack mode, there is no disruption to the service if a client requests an IPv4 address.

Networks Announcing IPv6 Over Time: A Short Update

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.

IP Address Management as a Service on the Cloud

Consumption of software as a service with a usage-based business model has gained incredible popularity in recent years. On the other hand, other cloud services such as infrastructure and platform as a service are just starting to pick up. While compute and storage are by the far the most commonly used cloud infrastructure services, few consider core network services such as IP Address Management (IPAM) as something that could be utilized over the cloud.

CENTR Paper on Fifth World Telecommunication/ICT Policy Forum

Many nations, particularly from the developing world, look to the International Telecommunications Union (ITU) for advice on telecommunications issues and, increasingly, Internet governance issues. The ITU's Fifth World Telecommunication / ICT Policy Forum (WTPF-13), 14-16 May 2013, Geneva, Switzerland, will be the first WTPF to focus exclusively on Internet issues.
