First Broad Internet Census Since 1982 Reveals Surprising Number of Unused IPv4 Addresses

In the upcoming Internet Measurement Conference being held next week in Vouliagmeni, Greece, a team of six researchers will be presenting a paper called "Census and Survey of the Visible Internet," based on a comprehensive census of more 2.8 billion allocated IP addresses on the Internet. The research is claimed to be the first comprehensive census of its kind in more than two decades. more

When an IP Address Does Not Equal Individual Culpability - Breaking Glass Pictures v Does, DAZ 2013

Something bad happens online. I can tie that something-bad back to an IP address. Do I know who did the bad thing? According to the Federal District Court in Arizona, I don't. An IP address may identify the owner of an Internet access account; it does not identify who was online at that particular time and who may be responsible for the actions in question. In Breaking Glass Pictures v Does, DAZ 2013, Plaintiff brought a claim for copyright infringement, wants early discovery, but the court is refusing. more

ARIN Statement on the Future of Addressing Policy

ARIN has just released a statement on the future of addressing policy. Specifically addressing the future of IPv4 addressing. What ARIN does is to emphasize the current policies and say they will be enforced even stronger than today if needed. I.e. there is no announcement of a change in policy. more

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. more

Measuring World IPv6 Launch: Comparing IPv4 and IPv6 Performance

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. more

IPv6 : Rumours Are More Accurate Than Predictions

As rumours tend to be more accurate than predictions, the last /8's are hanging already on this years Christmas tree and one should hurry to get hold of a small little RIR block to put on next year's tree. I will miss the decade of heated and passionate debates between Tony Hain and Geoff Huston on when the exhaustion would actually happen. Estimates ranged all the way from 2008 to 2020 with Tony predicting early demise of IPv4 addresses while Geoff initially thought exhaustion would come later. As time passed the interval converged and here we are. more

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. more

Implications of DoD IPv6 Mandate on IPv4 Market

Recent Department of Defense IPv4 activity and announcements about IPv6 indicate a shift in their perspective and suggest potential impacts on the IPv4 address market. The shift could include the release of up to 175 million IPv4 addresses in the coming years, creating a risk of a glut in the market. For perspective, the market has transferred 380 million addresses over eleven years. more

‘The Global Village’ Idiot

I recall from some years back, when we were debating in Australia some national Internet censorship proposal de jour, that if the Internet represented a new Global Village then Australia was trying very hard to position itself as the Global Village Idiot. And the current situation with Australia's new Data Retention laws may well support a case for reviving that sentiment. more

The Hidden Value of IPv4 Addresses

All devices that connect to the internet need unique addresses. The number of IP addresses is limited, creating a demand for addresses worldwide, particularly from the cloud computing industry. This demand has raised the value of IPv4 to levels that the internet's original developers didn't predict, in part because the internet was considered an experiment at the time. Of course, use - and so demand -- has exceeded anyone's realistic expectations. more

The ISP Industry: Concentrated or Diverse?

In August 2010, we looked at the growth in RIPE NCC membership and concluded that the number of new RIPE NCC members is still growing at an amazing pace, even during the recent economic downturn... This time we are looking at the different sizes of RIPE NCC members over time. It is often claimed that there is massive consolidation happening in the ISP community, especially in times of economic difficulties like in the early 2000s and now. We were curious to find out if this is really the case. 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

Watch Live - What Does “Success” For IPv6 Look Like? (Briefing Panel on Nov 5)

Now that IPv6 deployment is happening in major networks around the world, the question becomes -- what does "success" look like for IPv6? How much IPv6 traffic is "enough"? What are major milestones we should be tracking in IPv6 deployment? What is next for IPv6? more

RIPE NCC to Conduct Live Measurements for World IPv6 Day

RIPE NCC has announced plans to conduct live measurements for World IPv6 Day on 8th June 2011. The not-for-profit organization has set to measure connectivity to World IPv6 Day participants; "the IPv6 Eye Chart tests visibility of all World IPv6 Day participants and other sites that are already dual-stacked on a single web page." RIPE NCC says the process will help to find out if there are problems accessing these websites, both before and during World IPv6 Day. more

NFV Orchestration Without Network Visibility: OS MANO Needs Operational Improvements

Open Source (OS) Management and Orchestrations (MANO) is a European Telecommunications Standards Institute (ETSI) initiative that aims to develop a Network Function Virtualization (NFV) MANO software stack, aligned with ETSI NFV. The main goal of MANO is to simplify the onboarding of virtual network components in telco cloud data centers. The initiative has gained impressive momentum among leading Communication Service Providers (CSPs) around the world as part of their NFV programs. more
