The Internet Infrastructure: Stability vs. Innovation

Stratton Sclavos of VeriSign distills the essence of the SiteFinder controversy in his CNet interview...There is a subtle but essential misunderstanding here. Innovation can and should happen in Internet infrastructure, but there are a handful of core elements that must remain open and radically simple if the Internet is to remain, well, the Internet. These include TCP/IP, SMTP, HTTP, BIND, BGP, and the DNS (especially the .com registry). Any change in these protocols should be very carefully vetted through a consensus-based process. more

Why Do We Care About Names and Numbers?

An article based on the most recent study for the European Commission on the Policy Implications of Convergence in the Field of Naming, Numbering and Addressing written by Joe McNamee and Tiina Satuli of Political Intelligence.

"With relation to the Internet and also IP addresses, the "scarcity" is more complicated: there are not only intellectual property issues with regards to domain names, but there is also an issue of managing the integrity of the system. For any naming or numbering system to work, it is essential that the names and addresses used cannot be confused with any other -- in other words, no one system can have two end-points with the same fully qualified number or name..." more

Do We Need IPv4 at Home/SOHO Any More?

CLAT/NAT64 is utilized across many mobile networks globally, and I am only talking about Ethernet and Wi-Fi in home and small office/home office (SOHO) environments. I experimented by completely disabling IPv4 at home and established a SSID where my MacBook Pro operates without an actual IPv4 address. The MacBook supports CLAT (RFC 6877), and by implementing PREF64 (RFC 8781) and DHCP Option 108 (RFC 8925) in my network, I was able to achieve a 100% IPv6 environment. more

How Much Did the U.S. Wireless Carriers “Earn” From “Location Information Aggregators”?

The FCC lawfully fined U.S. facilities-based wireless carriers nearly $200 million for selling highly intrusive location data about subscribers without their "opt-in" consent. In Section 222 of the Communications Act, Congress comprehensively specified how the carriers bore an affirmative duty of care not to disclose clearly defined Customer Proprietary Information ("CPNI"). The Act explicitly required the FCC, and no other agency, to protect telecommunications consumers. more

A Brief Primer on Anti-Satellite Warfare Tactics

Satellites make it possible for governments to provide essential services, such as national defense, navigation, and weather forecasting. Private ventures use satellites to offer highly desired services that include video program distribution, telecommunications, and Internet access. The Russian launch of a satellite, with nuclear power and the likely ability to disable satellites, underscores how satellites are quite vulnerable to both natural and manmade ruin. more

The Christmas Goat and IPv6 (Year 14)

A new year and a new goat with new conditions, the goat was slowly eaten by jackdaws, and in the end, almost only the frame remained. This was really slow TV for the devastation… You can read more on Wikipedia about the devastating jackdaws and the straw... 36% IPv6 is equal to last year, and I had high hopes as Telia (AS3301) has made great progress in IPv6 and that Sweden should be the dominant country.  more

Call the Routing Police!

There was a somewhat unfortunate outage for a major communications service provider in Australia, Optus, in mid-November. It appears that one of their peer Border Gateway Protocol (BGP) networks mistakenly advertised a very large route collection to the Optus BGP network, which caused the routers to malfunction in some manner. more

Notes from NANOG 89: Trust and Network Infrastructure

Trust is such a difficult concept in any context, and certainly, computer networks are no exception. How can you be assured that your network infrastructure is running on authentic platforms, both hardware and software and its operation has not been compromised in any way? more

China Mandates IPv6 for Router Manufacturers Starting December 1

In a significant move to advance IPv6 adoption, China's Ministry of Industry and Information Technology has directed local router manufacturers to default to the IPv6 protocol from December 1, 2023 onwards. more

What Happened to Quantum Networks?

A few years ago, there were a lot of predictions that we'd see broadband networks converting to quantum technology because of the enhanced security. As happens with many new technologies, quantum computing is advancing at a slower pace than the wild predictions that accompanied the launch of the new technology. more

The Causes of Network Outages: Underlying Causes, Growing Threats and Industry Implications

The Uptime Institute (UI) is an IT industry research firm best known for certifying that data centers meet industry standards. UI issues an annual report that analyzes the cause of data center outages. The causes for data center outages are relevant to the broadband industry because the same kinds of issues shut down switching hubs and Network Operations Centers. more

2023 Routing Security Summit Starts July 17 - Participate Virtually

Interested in learning more about routing security? How it can affect your connectivity supply chain? What are best practices for enterprises and organizations? What is the role of CSIRTs in securing routing? What are governments doing now, and planning to do in the future around routing security? more

Happy 50th Birthday Ethernet

ome 50 years ago, at the Palo Alto Research Centre of that renowned photocopier company Xerox, a revolutionary approach to local digital networks was born. On the 22nd of May 1973, Bob Metcalf authored a memo that described "X-Wire," a 3Mbps common bus office network system developed at Xerox's Palo Alto Research Center (PARC). more

How to Design a Decentralized Social Media Protocol – Be Ruthless About Technical Requirements and Eager to Build Coalition

Project Liberty's Institute sat down with Dave Clark, an early contributor to the TCP/IP protocols that built and run the Internet, and one of the expert advisors on DSNP, the Decentralized Social Networking Protocol. Dave Clark is Senior Research Scientist at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) and Fellow of the National Academy of Engineering and the American Academy of Arts and Sciences. more

50 Years of Ethernet

The idea for Ethernet was born fifty years ago in May 1973 when Robert Metcalf coined the word Ethernet. He had been studying ALOHAnet, developed at the University of Hawaii in 1971 and was the first public demonstration of a wireless packet data network. Metcalf used the work Ethernet as a reference to luminiferous aether, a concept postulated in the 17th century to explain how light could be transmitted through a vacuum. more
