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

What is Bring Your Own IP (BYOIP)?

An IPv4 address identifies your connection to the online world. IP addresses make it possible to host websites, manage secure communication, and engage in countless other essential, internet-related activities. Typically, when migrating to a new cloud provider, a business has only one path: lease the provider's IP addresses. But what if a business already has a block of IP addresses? 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

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
