A Look Back at the World of IP Addressing in 2020: What Changed and What It Means

Time for another annual roundup from the world of IP addresses. Let's see what has changed in the past 12 months in addressing the Internet and look at how IP address allocation information can inform us of the changing nature of the network itself. Back around 1992, the IETF gazed into their crystal ball and tried to understand how the Internet was going to evolve and what demands would be placed on the addressing system as part of the "IP Next Generation" study.  more

Why Not Connect Cuba’s Gaspar Social Streetnet to the Internet?

I've been covering Cuban streetnets (local area networks with independent users that are not connected to the Internet) for some time. Reader Doug Madory told me about Gaspar Social, a new streetnet in Gaspar, a small town in central Cuba. Gaspar Social opened to the public last October and has grown quickly -- about 500 of Gaspar's 7,500 residents are now users. Streetnets are illegal in Cuba and the government has ignored some and cracked down on others... more

A Seismic Shift: IPv4 Numbers Becoming Transferable and Consequently Property

A Tipping Point for the Internet? Catching the precise moment of a tectonic shift in a global system as large and important as the Internet may be viewed as an exercise in the improbable. However, I point out in this summary that I think we are precisely in the midst of such a shift... more

A DNS View of Lockdown

At NANOG 79 earlier this month Craig Labowitz from Nokia Deepfield presented on the impact on the COVID-19 pandemic on Internet use. The approach to the analysis used real-time streaming telemetry from Communication Service Provider (CSP) backbone and aggregation routers, and the data analysis covered content provider networks in North America, Europe and parts of Asia. more

Google Ends Domain-Fronting Feature Used by Censorship Tools

A recent change in Google's network architecture has put a stop to a so-called "domain-fronting" feature that allowed services use Google's network to get around state-level internet blocks. more

Will the Cloud Kill Telecom Vendors?

There are many big questions in telecom these days, and this is one that's on my mind right now. Over the past few months, I've participated in events or briefed with leading vendors in our space, namely Avaya, ShoreTel, BroadSoft, Aastra, Metaswitch, Mitel, Interactive Intelligence, and this week Cisco. Every analyst has their own core circle of vendors they stay close to, but I'd say that's a pretty fair representation of who's driving telecom. To varying degrees, all of these vendors have a cloud story, and the more I hear it, the more I start to wonder what it really means. more

ECFiber: Building a Fiber-to-Premises Network in the Rural United States

Nestled in the northeastern part of the United States is the small state of Vermont, the 14th State to join the United States in 1789. Its name comes from the French, in which 'vert montagne' means 'green mountain.' and it is known as the Green Mountain state. With only about 625,000 inhabitants, it is the 45th state out of 50 in size, and 49th of 50 in number of people, even less populated than Alaska. more

Global IPv6 Deployment Now Passes 10%!

Global IPv6 deployment just passed a major milestone over the past few days when Google's IPv6 adoption statistics showed over 10% of users connecting to Google's sites coming in over IPv6. Considering that only two years ago I wrote here on CircleID about IPv6 passing the 3% adoption mark, this is a great amount of growth to see! If you look on the "per-country" tab of Google's stats you will see that in some countries deployment is much higher. For example, around 25% in the USA, Portugal and Germany, 31% in Switzerland and 44% in Belgium. more

Nigerian Cable Company Takes Blame for Misrouting Google’s Global Traffic Through China

Much of Google's traffic yesterday appeared to be re-routed through Russia and dropped at China Telecom. The issue raises serious concerns as a possible traffic hijacking incident. more

US Senators Urge Canada to Drop China’s Huawei Technologies in Building Future Telecom Networks

U.S. Senators Mark Warner, a Virginia Democrat, and Marco Rubio, a Florida Republican, both critics of China, have urged Canada to consider dropping China's Huawei Technologies from helping to build next-generation 5G telecommunications networks. more

Recent Enhancements to ARIN’s whoIS-RWS Service

ARIN deployed a series of enhancements to its Whois-RWS service today. This includes enabling CIDR support and IPv6 lookups in the search box on the web page, provided plain text rendering of lists of ASNs and networks on the web - plus enhanced CIDR query matching on WHOIS port 43. more

Foreign Hackers Attack Canadian Government

An unprecedented cyberattack on the Canadian government also targeted Defence Research and Development Canada, making it the third key department compromised by hackers, CBC News has learned. ... While there is no definitive proof, of course, that China was behind these attacks, there is a lot of circumstantial evidence that points in that direction. China (allegedly) has a long history of engaging in espionage activities in order to gain access to information. In the United States, this is sometimes referred to as cyber warfare, but I think that cyber espionage is a better choice of terms. more

IPv6 or IPv4? What Will We See in the First Wave of LTE Networks?

All the talk early this year seems to be about LTE deployment to alleviate chronic Apple and other smartphones induced indigestion on the AT&T and other major Mobile Networks swamped by data traffic. The telluric shift albeit the user will not care or should not notice is that when he or she will power on that smartphone or whatever the communicating Swiss Knife will be called, it will request an IP address to complete an IP based call. more

DNSSEC and DNS over TLS

The APNIC Blog has recently published a very interesting article by Willem Toorop of NLnet Labs on the relationship between Security Extensions for the DNS (DNSSEC) and DNS over Transport Layer Security. Willem is probably being deliberately provocative in claiming that "DoT could realistically become a viable replacement for DNSSEC." If provoking a reaction was indeed Willem's intention, then he has succeeded for me, as it has prompted this reaction. more

The Spamhaus Distributed Denial of Service - How Big a Deal Was It?

If you haven't been reading the news of late, venerable anti-spam service Spamhaus has been the target of a sustained, record-setting Distributed Denial-of-Service (DDoS) attack over the past couple of weeks... Of course, bad guys are always mad at Spamhaus, and so they had a pretty robust set-up to begin with, but whoever was behind this attack was able to muster some huge resources, heretofore never seen in intensity, and it had some impact, on the Spamhaus website, and to a limited degree, on the behind-the-scenes services that Spamhaus uses to distribute their data to their customers. more
