Many in the network security field may be familiar with the phrase: "It's always DNS." This is a popular meme within the industry, often making reference to the internal domain name system (DNS), the dynamic host configuration protocol (DHCP) part of a company's online network, that whenever there is a network issue, it's always an issue with DNS. more
With 1,675 satellites launched and 500,000 requests for service in the United States alone, SpaceX Starlink clearly leads all would-be providers of low Earth orbit (LEO) internet service to consumers. However, it is arguable that Telesat Lightspeed is in the lead, or contending for the lead with SpaceX, in non-consumer enterprise, government, mobile backhaul, mobility and rural community markets. more
There is a lot of news recently about low-orbit satellite broadband. There is recent news concerning the three primary companies that will be vying in the space. First is Jeff Bezos Project Kuiper, which is still likely to get a brand name at some point. Project Kuiper has contracted with United Launch Alliance, a joint Boeing-Lockheed Martin venture, for the first nine broadband rocket launches. more
I'm happy to report (mostly) positive feedback on my last article that examined how the multistakeholder model tackled, and tackled well, Phase 1 of the review of all Rights Protection Mechanisms. While bad news may sell more clicks, a little good news from time to time also appears to be welcome. Good news also reminds us of how fortunate we are to have a private sector ICANN with a multistakeholder model of policy development... more
In September 2015, John Levine asked why ICANN should be considered a tax-exempt organization following the completion of the U.S. government's transition of technical management of the Internet's Domain Name System (DNS). The U.S. Internal Revenue Service (IRS) determined that ICANN was an exempt organization in 2000 and, inarguably, circumstances have evolved materially since then. more
I was looking back at industry reporting a year ago after the impact of the pandemic first hit our broadband networks. Almost every big ISP issued press releases talking about how well it had weathered the pandemic and bragged about the resiliency of its networks. It turns out that these ISP press releases largely missed the point. They are right that their networks didn't crash, but once we understood the nature of the changes in broadband traffic due to the pandemic, that wasn't a big surprise. more
Email Campaign builders (marketers) are flying blind. I know ESPs are genuinely timely about rolling out new products for their marketers, but there is a colossal gap in adopting data science and MLops into the email campaign building workflow. Even MailChimp does not seem to have the answer just yet, and half-baked attempts over the years to optimize the subject line haven't been inspiring. more
One of the basic tools in network design is the so-called "stacked" protocol model. This model was developed in the late 1970s as part of a broader effort to develop general standards and methods of networking. In 1983, the efforts of the CCITT and ISO were merged to form The Basic Reference Model for Open Systems Interconnection, usually referred to as the Open Systems Interconnection Reference Model or the "OSI model." more
It has been a long time coming. In the world of global 5G security, there is only one principal forum. The somewhat cryptically named 3GPP SA3 is dedicated to 5G security and holding its 103rd meeting electronically next week from 17 to 28 May with 772 submitted documents and 189 participants registered. SA3 meets every 60 days and exists at the security center of an ecosystem of numerous technical groups encompassing many hundreds of companies, industry organizations, and government agencies worldwide. more
I recently saw an article in FierceWireless that reports that Huawei thinks we are going to need an intermediate step between 5G and 6G, something like 5.5G. To me, this raises the more immediate question about why we are not talking about the steps between 4G and 5G? The wireless industry used to tell the truth about cellular technology. You don't need to take my word for it... more
Recently, I have been reporting on a highly questionable auction scheme for a single domain name, o.com, which is currently being improperly warehoused by ICANN along with a number of other .com and .net domain names. This violates ICANN's Bylaws -- but, so what? more
It's now been a decade since the world officially ran out of blocks of IP addresses. In early 2011 the Internet Assigned Numbers Authority (IANA) announced that it had allocated the last block of IPv4 addresses and warned ISPs to start using the new IPv6 addresses. But here we are a decade later and not one of my clients has converted to IPv6. more
The report, "A Decade of Passive DNS" provides a longitudinal analysis of the use and popularity of top-level domains over a ten-year period. The findings are based on what Farsight Security has seen in passive DNS from 2010-2019 based on a ten-year data rollup, excluding DNSSEC-related records. This study allows us to report on four measures for that period for each of the 1,576 IANA-recognized TLDs. more
There have been rumors for years about merging Dish Networks and Direct TV to try to gain as much market synergy as possible for the two sinking businesses. It's hard to label these companies as failures just yet because between two companies collectively still had 21.8 million customers at the end of 2020 (DirectTV 13.0 million, Dish 8.8 million). This makes the two companies collectively the largest cable TV providers, with Comcast at 19.8 million and Charter at 16.2 million. more
"2021 will be another challenging year for us, but it's also the year that our future development strategy will begin to take shape," said Eric Xu, Huawei's Rotating Chairman. Huawei generated CNY152.2 billion in revenue, a 16.5% decrease year-on-year. The Network Business continued to grow. It wasn't officially announced1, but consumer products other than phones probably increased sales. The fitness tracker, earbuds, and watches are winning strong reviews. more
