Where are DNS Root Servers? See them on Google Maps

DNS root servers function as part of the Internet backbone, as explained in Wikipedia, and have come under attack a number of times in the past -- although none of the attacks have ever been serious enough to severely hamper the performance of the Internet. In response to some of the common misconceptions about the physical location and total number of DNS root servers in the world, Patrik Faltstrom has put together a visual map on Google, pin-pointing the approximate location of each server around the world. more

Cloud Computing Types: Public Cloud, Hybrid Cloud, Private Cloud

It's no secret that I don't very much like this whole private cloud or internal cloud concept... on the basis that while advanced virtualisation technologies are valuable to businesses they are a severe short sell of what cloud computing is ultimately capable of. The electricity grid took over from the on-site generators very quickly and I expect cloud computing to do the same with respect to private servers, racks and datacenters... more

China’s Censorship Blowback

I'm not sure what the Chinese government is thinking, or whether certain parts of certain ministries and party apparatus have gotten completely out of control. Until recently, it had seemed to me that the Chinese government was managing its censorship system with surprising success... But this month, something shifted. It's unclear whether the shift is long-lasting or just temporary madness until the PRC's 60th anniversary on October 1st. more

Top Public DNS Resolvers Compared

At ThousandEyes, we've always been curious about the performance of various public DNS resolvers -- especially since Google threw their hat in the ring back in 2009. We satisfied our curiosity this week, so we thought we'd share the results. Here's how we did it. more

Cuba Rolls Out 3G Mobile Access

After several months of trials, ETECSA announced the availablity of third-generation mobile access to their national intranet and the global Internet in a televised "round table." The prices are quite steep for a typical Cuban and I suspect there would be relatively few subscribers among the 34% of the population that is not yet covered. Furthermore, many users will have to buy new phones to use the service. (There are still 1,084 second-generation mobile base stations in Cuba). more

Domain Tasting Target of US Federal Cybersquatting Lawsuit

So Domain Tasting, where registrants (who may also be registrars) taste names and keep only those that have economic value, is now the target of a federal cybersquatting lawsuit, brought about by lawyers for major brand name retailers Neiman Marcus and Bergdorf Goodman against major domain name registrar Dotster. This Dotster lawsuit involves allegations of cybersquatting by registrars who use the Create Grace Period, which is mandated by ICANN for global registries... more

Letting DNS Loose

RFID tags, UPC codes, International characters in email addresses and host names, and a variety of other identifiers could all go into DNS, and folks have occasionally proposed doing just that. Its really just a question of figuring out how to use the DNS -- its ready to carry arbitrary identifiers. And by the way, this isn't a new idea, see RFC 1101 for proof, although even earlier I designed the DNS in the early 1980s to allow it to be so, but it seemed too far fetched to document for a while. ...I was in Geneva for a WSIS meeting of CTOs, and was surprised that the various organizations (ITU, ICANN, ISOC) haven't figured out that they need each other to make this technology work, rather than asserting ownership. more

Why I Am Participating in the ORSN Project

As a long time supporter of the universal namespace operated by IANA, it may come as a surprise that I have joined the Open Root Server Network project (ORSN). I'll try to explain what's going on and what it all means. ...If one of my kids, or anybody anywhere, sits down in front of a web browser and keys in a URL, it ought to just work. They ought to see the same web page that anybody else would see, no matter what country they're in or what their ISP wants or what their local church or government wants. This universality of naming is one of the foundations on which the Internet was built, and it is how the Internet fosters economic growth and social freedoms. It's what makes the Internet different from old Compuserve, old AOL, old MSN, old Minitel, and everything else that has come -- and gone -- before... more

DNS Changer

One fine night in November 2011 I got an opportunity to get my hands dirty, working on a project for the United States Federal Bureau of Investigation (FBI). They were planning to seize a bunch of computing assets in New York City that were being used as part of a criminal empire that we called "DNS Changer" since that was the name of the software this gang used to infect a half million or so computers. more

Sender Address Verification: Solving the Spam Crisis

There are many companies in the spam-fighting business and most, if not all, claim to be hugely successful. Yet spam is exponentially more prevalent today than it was just 2 years ago. How can one conclude that today's anti spam solutions are working? This year spammers will use machine-generated programs to send trillions of unsolicited email. Thankfully, a new anti-spam technology has made its way into the market. more

Do Not Enter - It’s XXX

There soon will be a central place for Web surfers to dwell in a forbidden cyber land of adult fantasies, sex, dark rituals and total taboos. Finally, ICANN has given in to the pressure and has tossed a big rock across the turbulent e-commerce ocean. It has approved a new suffix, .xxx, for adult-only porn sites, creating ripples and debates in ever so confusing global cyber branding times when cyber global domain name challenges are being fought in the complex earthly trademark realities. Three things are bound to happen... more

China’s New Domain Names: Lost in Translation

This morning I got a bunch of alarmist messages from friends asking about this English-language People's Daily article titled: China adds top-level domain names. The paragraph that's freaking people out is: "Under the new system, besides "CN", three Chinese TLD names "CN", "COM" and "NET" are temporarily set. It means Internet users don't have to surf the Web via the servers under the management of ICANN..." Not for the first time, it appears that the People's Daily's English translation is very misleading. more

How to Stop Spam

I got a letter the other day from AOL postmaster Carl Hutzler, about how the Internet community could get rid of spam, if it really wanted to. With his permission, here are some excerpts. "Spam is a completely solvable problem. And it does not take finding every Richter, Jaynes, Bridger, etc to do it (although it certainly is part of the solution). In fact it does not take email identity technologies either (although these are certainly needed and part of the solution)." more

Help! My Domain Name Has Been Hijacked!

They are out there. In Internet Cafes and dark rooms from New York to Hong Kong to Iran, the domain name hijackers are plotting to steal your domain names. Fortunately, there are some steps that you can take to protect yourself against losing your domain names. ...Registrars are often skeptical of claims of domain hijacking, and the hijackers often "launder" the domain names to look as if they have sold them to third parties... By the time you discover that your domain name has been stolen, it may be at its third or fourth different registrar in the name of a completely different party... more

Fake Bank Site, Fake Registrar

In our continuing review of Rogue Registrars we have stumbled upon on a very elaborate fake banking site for "Swiss Bank" or "Bank of Switzerland". To the casual Internet consumer this site probably appears legitimate, but a number of clues tip off the fraud. Phishing sites are everywhere so this does not immediately raise eyebrows until you review the Thick WHOIS record for the domain. more
