30 Years Ago Today, the Switch to TCP/IP Launched Today’s Internet

It was 30 years ago today, on January 1, 1983, that the ARPANET had a "flag day" when all connected systems switched from using the Network Control Protocol (NCP) to the protocols known as TCP/IP. This, then, gave rise to the network we now know as the Internet. more

IPv6 Subnetting - The Paradigm Shift

Almost every conversation I have with folks just learning about IPv6 goes about the same way; once I'm finally able to convince them that IPv6 is not going away and is needed in their network, the questions start. One of the most practical and essential early questions that needs to be asked (but often isn't) is "how do I lay out my IPv6 subnets?" The reason this is such an important question is that it's very easy to get IPv6 subnetting wrong by doing it like you do in IPv4. more

Is IPv6 a Boon to Criminals and Foe to the FBI?

Declan McCullagh recently opined that the "FBI [and the] DEA warn [that] IPv6 could shield criminals from police." His post was picked-up relatively widely in the past few days, with the headlines adding more hyperbole along the way. So just how real is this threat? Let's take a look. more

Accountability, Transparency, and… Consistency?

ICANN Compliance now has two conflicting answers on record concerning the enforceability of RAA 378 on WHOIS inaccuracy. This is a topic of extreme importance and one we are trying to get to the bottom of. ...inconsistency needs to be resolved as it directly impacts the current RAA negotiations and certainly before new gTLDs are deployed. more

The Business Parallels Between IPv6 and DNSSEC

For two things that would seem to be completely unrelated there is an interesting parallel between IPv6 and DNSSEC. In both cases there is a misalignment of interests between content providers and service?providers. Content providers aren't highly motivated to deploy IPv6 because only a small proportion of users have v6 connectivity and even fewer only have v6. Service providers aren't anxious to deploy IPv6? because there isn't a lot of content on v6, and virtually none exclusively on v6 - so they don't expand the universe of interesting stuff on the web by deploying IPv6. Basically the same things could be said about DNSSEC. 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

Intune Collapses the OSI Model

While a great deal of attention has recently been paid to the enormous amount of change that is taking place at the edge of the network with smartphones, tablets, apps, Web2.0 etc, massive changes are also underway on the network side. The current network has been designed over a period of thirty years and it is due for a serious overhaul to keep abreast of changes in the industry in general. more

Wither WHOIS!: A New Look At An Old System

No, that title is not a typo. The WHOIS service and the underlying protocol are a relic of another Internet age and need to be replaced. At the recent ICANN 43 conference in Costa Rica, WHOIS was on just about every meeting agenda because of two reasons. First, the Security and Stability Advisory Committee put out SAC 051 which called for a replacement WHOIS protocol and at ICANN 43, there was a panel discussion on such a replacement. The second reason was the draft report from the WHOIS Policy Review Team. more

Providing Persistent Domain Names Under .ARPA

Some domains are too big to fail. Quite apart from the obvious ones like google.com and facebook.com, upon whose availability our everyday lives depends, there are many others upon which the infrastructure of the Internet (and much of the modern world itself) depends. These are domains like w3.org and ietf.org, which host the technical specifications which describe the World Wide Web and the Internet themselves. more

FCC to Hold Two December Workshops on PSTN Transition to New Technologies

The US Federal Communications Commission (FCC) recently issued a public notice that it will be holding two workshops on the transition of the public switched telephone network (PSTN) to "new technologies" such as voice-over-IP (VoIP). The workshops will be held on December 6 and 14, 2011, at the FCC's office in Washington, DC. The public notice states the goal as... more

The Invisible Hand vs. the Public Interest in IPv4 Address Distribution

In the efforts to promote the public interest over that of monied interests in Internet Governance few issues are clear cut. One issue that has recently been discussed is that of requiring a "needs assessment" when transferring IP addresss blocks from one organisation to another (in the same or different RIR regions) or indeed when requesting IP resources from your friendly RIR. more

The Rising Technical Challenges of Networking at Home

For me, one of the more interesting sessions at the recent IETF 81 meeting in July was the first meeting of the recently established Homenet Working Group. What's so interesting about networking the home? Well, if you regard challenges as "interesting", then just about everything is interesting when you look at networking in the home! more

Searching Under Lampposts with DKIM

Email is a complex service and email abuse adds confusing deceptions. Worse, like postal mail and even telephone service, Internet mail is inherently open, flexible and even anonymous, making things much easier for abusers. Bad actors hide their true identity and their true purpose. Most other communication tools for users also are also quite open, and problems with email are being replicated elsewhere, such as instant messaging and social media. more

RFC 1918 Address Space: Why It Was Needed then and How It Will Change in IPv6!

Recently, my firm has seen a lot of interest come from Enterprises seeking IPAM/DNS tools. We predicted that IPv6 adoption and the need for automation software/tools would follow the Internet ecosystem's supply chain starting with Service Providers consisting of ISPs, I/PaaS, ASPs, then content providers (mostly a service really), then Enterprises, followed by SMBs & Consumers. While good for business, it has also forced us to revisit and think thru many TCP/IP protocol standards... more

Court Approves Nortel’s Sale of IPv4 Addresses to Microsoft

Yesterday morning (26-April-2011), in US Bankruptcy Court for the District of Delaware, Judge Kevin Gross signed an order authorizing Nortel's sale of IPv4 addresses to Microsoft. This is an important moment for the Internet community, as it represents the beginning of a new market-based mechanism for the distribution of scarce IPv4 address resources. As the various Regional Internet Registry (RIR) organizations exhaust their supply, traditional "needs-based" distribution will become impossible. more
