Alignment of Interests in DNS Blocking

I've written recently about a general purpose method called DNS Response Policy Zones (DNS RPZ) for publishing and consuming DNS reputation data to enable a market between security companies who can do the research necessary to find out where the Internet's bad stuff is and network operators who don't want their users to be victims of that bad stuff... During an extensive walking tour of the US Capitol last week to discuss a technical whitepaper with members of both parties and both houses of the legislature, I was asked several times why the DNS RPZ technology would not work for implementing something like PROTECT-IP. more

IPv6 Security Myth #7: 96 More Bits, No Magic

This week's myth is interesting because if we weren't talking security it wouldn't be a myth. Say what? The phrase "96 more bits, no magic" is basically a way of saying that IPv6 is just like IPv4, with longer addresses. From a pure routing and switching perspective, this is quite accurate. OSPF, IS-IS, and BGP all work pretty much the same, regardless of address family. Nothing about finding best paths and forwarding packets changes all that much from IPv4 to IPv6. more

The .net Top Level Domain and Cross-Coupled Failures

The .net Top Level Domain (TLD) contains the names of the main group of DNS root servers as well as the names of the servers for several other large TLDs, such as .com, .org, .arpa and .mil. Most of the focus about the .net redelegation has concerned the quality of the registration systems. But that is a minor matter next to the quality of the name server operation.  more

Gmail as an Email Honeypot

You all remember cybersquatting, a popular sport in the late 90s, right? McDonalds.com, JenniferLopez.com, Hertz.com and Avon.com thankfully all point to the right web sites today, but thaiairline.com, mcdonald.com, luftansa.com, gugle.com, barnesandnobles.com and other misspellings are fake web sites intended to trap the casual surfer with a hand that's a bit too much quicker than the eye... If you want to go to the McDonalds web site, you don't even spend the 10 seconds to look it up -- you will type McDonalds.com and expect to see the latest dollar meal menu. But the same is true for the other popular form of communication -- email... more

Rise of the Caribbean Mobile Market

It is no secret that in the Caribbean people are crazy about their cell phones. In fact, the Caribbean has one of the highest levels of mobile phone penetration in the world. According to a report from BuddeComm, an Australia-based telecom research firm, mobile phone penetration in Latin America and the Caribbean reached an estimated 80% in early 2009, well above the world average which was about 58%. The report stated that Latin America and the Caribbean together now account for an estimated 12% of the world's 3.97 billion mobile subscribers. more

2010 Domain Name Year in Review - Oh, What A Year It Was!

Many of us were expecting radical changes in 2010 to the domain name market. There definitely were some of those -- just not the ones I expected. From the seizure of domains names by the US Government to ICANN's removal of restrictions on Registry/Registrar cross-ownership, 2010 was a year full of surprises. In this post, I've compiled what I think were the biggest domain name stories in 2010. more

Swedish Regulator Bans Inclusion of Letters “b”, “a”, “n”, “k” in Domain Names Under .SE

Swedish Regulator PTS have today notified .SE, the Swedish (.SE) TLD registry that they have to change the rules... In short, the decision implies that any form of the sequence of the characters "b", "a", "n", "k" are illegal in domain names in Sweden. Further that checks of what domain names are registered are to be checked before registration. more

Some Whois Lookup Services Might be Broken

There are thousands of sites and services on the 'net that offer domain name whois lookup services. As of last night, many of them may have stopped working. Why? Many of them rely on fairly rudimentary software that parses the whois from Verisign (for .com and .net) and then relays the query to the registrar whois. The site or service then displays the whois output from the registrar's whois server to you. more

Cloud Redundancy: How Amazon Should Repair Credibility

I'm curiously puzzled, but not entirely surprised, how a company such as Amazon (NASDAQ: GS) allowed its servers to be interrupted for any length of time due to severe storm damage in northern Virginia this past weekend. Companies using cloud servers are both expectant and dependent on being able to pull information from cloud sources to operate their businesses without interruption. After all, IT professionals have been preaching the security and reliability of the cloud for quite some time to manage large data off-site. Steps for Amazon to repair credibility should be transparent and swift. more

The Trouble With 6to4

In the transition from IPv4 to IPv6, the preferred solution for network endpoints is to have both native IPv4 and IPv6 connectivity (also called dual-stack connectivity). If a site cannot get native IPv6 connectivity, however, the IPv4 network endpoints can choose from a number of conversion technologies to connect to the IPv6 Internet. The most commonly used conversion mechanisms are 6to4, Teredo and tunnel-brokers. At recent RIPE meetings there have been claims that 6to4 connectivity is quite often broken. We were interested to find out how broken it really is. more

The IPv4 Market - 2018 Mid-Year Report

The number of IPv4 transactions and volume of IP addresses flowing to and from organizations in the ARIN region in the last 6 months put 2018 on track to be the most active year in the history of the IPv4 market. Nearly 25 million numbers were transferred in the first half of this year, more than doubling the volume of numbers transferred by this time last year and continuing the level of market activity in the last half of 2017 when just over 28 million numbers were transferred. more

Digital Culture Wars: Donald Trump’s “Make America Great Again” and China’s Social Credit System

We are on the cusp of a grave risk where unscrupulous groups with various agendas are using digital technologies to wage cultural war to stamp out dissent and gain control and power. The two most prominent recent examples are Donald Trump's "Make America Great Again" (MAGA) and China's Social Credit System (SCS). The following piece was prompted by work on the UDHR and Internet Governance series, for CircleID to deal with UDHR Article 27 and the role of culture, arts, and science in the life of the community.  more

Afilias’ Cynical Attempt to Secure a Windfall at Community Expense

On Friday, October 28, Afilias issued a public statement urging the Internet Corporation for Assigned Names and Numbers (ICANN) to nullify the results of its July 27, 2016 public auction for the .web new generic top level domain (gTLD) -- in which Nu Dotco, LLC (NDC) submitted the highest bid for .web -- and disqualify NDC from participation in the .web contention. The real issue here is whether ICANN should enforce the results of a fair and competitive public auction... more

The Unbelievably High Cost of the War Against Huawei

U.S. companies were selling $11 billion a year of parts to Huawei before the blockade. Losing those sales is just the start of the damage. Every other Chinese and Russian company is making sure to find non-US suppliers. The U.S. has threatened India and Turkey with sanctions as well. As other companies replace U.S. components, the impact will be tens of billions more than the $11 billion of Huawei suppliers. more

Chromecast Set to Revolutionise the TV

The principle behind Chromecast is probably the magic formula that is needed to finally revolutionise television watching. Google's latest product was launched yesterday... TV revolution didn't come from the traditional broadcasters or their suppliers. Everything developed by them has been aimed more at protecting their traditional business than at looking for completely new opportunities - truly new TV innovations will most certainly come from the direction that the broader market has taken since the arrival of the smartphones and the tablets. more
