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

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 Company You Keep

This story started earlier this year, with a posting to the Australian network operators' mailing list, asking if anyone had more information about why the web site that was operated by an outfit called "Melbourne Free University" was inaccessible through a number of major Australian ISPs. When they asked their local ISP if there was some issue, they were informed that "this was due to an Australian government request, and could say no more about it." more

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. more

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. 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

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

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. more

INET Denver: IPv4 Exhaustion and the Path to IPv6

Join IPv6 networking professionals from across North America, who will attend to learn the latest on IPv4 exhaustion and how to transition to IPv6. The INET Denver agenda will bring together top experts in the networking field to discuss the latest on IPv4 exhaustion in our market, and the TCO of IPv6. more

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. more

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. more

1,000th /22 Allocated from Last /8

On 14 September 2012, the RIPE NCC began allocating IPv4 address space from the last /8 we received from the Internet Assigned Numbers Authority (IANA). Nobody was entirely sure what would happen when we reached this point. Would there be a "run on the bank" for this final block of addresses? more

Cloud Security Hinges on IP Addressing

In the first part of this trilogy, I discussed the importance of automatically provisioned second generation DNS in connection with Software Defined Networking (SDN) and Software Defined Data Centre (SDDC). In the second post, I talked about IP addressing, private enterprise networks, and how DHCP does not meet the requirements of multitenant Infrastructure-as-a-Service (IaaS) cloud environments. I will now wrap up this trilogy by putting these two thesis into real-life context. more

Maslow's Hammer Meets the Software Defined Data Center

In my previous post, I talked about the significance of DNS in connection with the Software Defined Data Center (SDDC) and Software Defined Networking. Although the second generation DNS provisioning model I outlined should have seemed straight-forward enough, in real life it is anything but. In my view, the real-world complications of a seemingly trivial issue are largely related to how the network industry approaches IP addressing. more
