Two Stage Filtering for IPv6 Electronic Mail

I'm a guest at the MAAWG conference in San Francisco this week and several people have now mentioned to me the problem and the opportunity of anti-spam e-mail filtering for IPv6. Tomorrow is World IPv6 Day but since a bunch of the pieces have clicked together in my head I'll post this a day early. more

Google Fiber Project: Programming Key to Success

Google has officially rolled out its long-touted Google Fiber Project showcasing what broadband should look and feel like to all users. Yes, it sets the new standard for broadband connections with a 1Gig speedster, over 100 times faster than current broadband offerings in the U.S. Not-withstanding, just speed will not be the determining success factor; the availability of competitive programming will become the deciding judgment in Google's move to tout reasonable costs to bundled broadband. more

URLs: Ontologically Speaking

I was reading David Weinberger's reports on how the New York Times is planning on tackling its "link rot" problem where articles slip behind the pay-wall. Part of their solution appears to be to replace articles with their summaries. As usual, this got me thinking about telephony. Why don't phone calls and callers have URIs or URLs? ...Let's take addressing the endpoints first. Obviously, ENUM is one way of "Internetising" the phone number address space. more

“It’s Always DNS!” Why DNS Is the Biggest Single Point of Failure in the New Norm

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

Guowang, Renamed China SatNet, Will Be China’s Global Broadband Provider

In an earlier post, I described what looked like two forthcoming Chinese broadband constellations, Hongyun and Hongyan and in another post, I described a third, identified as "GW" at the time. All three were projects of state-owned enterprises China Aerospace Science and Technology Corp. (CASC) and China Aerospace Science and Industry Corp. (CASIC). There was pushback from those contending that a broadband constellation was redundant ... more

The IETF Evolution

The Internet Engineering Task Force (IETF) is a collaborative body that has developed internetworking specifications for more than five decades, successfully shaping the global marketplace of digital network equipment and services. Beginning as a kind of distributed think tank among network researchers in 1969, it evolved to become one of the world's most influential standards bodies. more

The Rise of Cyrillic Domain Names

This week, on a cruise ship navigating Russia's Neva river, around 250 domain registrars and resellers are gathered for the RU-CENTER annual domain conference. RU-CENTER is the largest Russian registrar in a market that is dominated by three companies. RU-CENTER and competitor Reg.Ru both manage around 28% of domains registered in the country's national suffix... RU-CENTER is also a figurehead for Russia's drive to make Internet use more palatable for those who are not natural ASCII writers. more

Is the Transition to IPv6 a “Market Failure?”

At the outset I should say that here I would like to restrict my view to the transition from the IPv4 Internet to the IPv6 Internet, and, in particular, to examine the topic of the appropriate market structure that lies behind the dual stack transition strategy, and the manner in which the Internet can transition from the universal use of IPv4 as the underlying datagram protocol to the universal use of IPv6. more

Lights Going Out on the Internet? Not Just Yet

In his article titled, "End of Life Announcement", John Walker (author of the Speak Freely application) makes a few arguments about Network Address Translation (NAT) that are simply not true: "There are powerful forces, including government, large media organisations, and music publishers who think this situation is just fine. In essence, every time a user--they love the word "consumer"--goes behind a NAT box, a site which was formerly a peer to their own sites goes dark, no longer accessible to others on the Internet, while their privileged sites remain. The lights are going out all over the Internet. ...It is irresponsible to encourage people to buy into a technology which will soon cease to work." more

Questioning the Illusion of Internet Governance

I confess, I don't get it. Much has been written about the apparent desire by the United Nations, spurred by China, Cuba, and other informationally repressive regimes, to "take control of the Internet." Oddly, the concrete focus of this battle -- now the topic of a Senate resolution! -- is a comparatively trivial if basic part of Net architecture: the domain name system. The spotlight on domain name management is largely a combination of historical accident and the unfortunate assignment of country code domains like .uk and .eu, geographically-grounded codes that give the illusion of government outposts and control in cyberspace. more

Emerging Cyber-Security Threats and Implications for the Private Sector

The new gTLD program will have a profound impact on the private sector's increasing dominance over Internet information resources and ownership of critical registry technical infrastructure assets. It is already anticipated that only the private sector will take full advantage of the commercial possibilities... However, the successful introduction of new gTLDs will also create new challenges of security for the private sector. more

In Memory of Jon Postel

Jonathan B. Postel, one of the Founding Fathers of the Internet passed away on October 16, 1998. Jon had a great deal of influence over how the Internet works and how it was designed. The following is a letter written by Vinton G. Cerf on October 17, 1998 in honor of Jon's death. The letter was called "I Remember IANA".

"If Jon were here, I am sure he would urge us not to mourn his passing but to celebrate his life and his contributions. He would remind us that there is still much work to be done and that we now have the responsibility and the opportunity to do our part. I doubt that anyone could possibly duplicate his record, but it stands as a measure of one man's astonishing contribution to a community he knew and loved." more

Why Are the EU Data Protection Authorities Taking Away Our Fundamental Right to be Safe?

What if we created a rule that gave everyone - good or bad - the right to hide their license plate, where they live, who they are, and just go incognito? What if we made it a right to walk into any building in the world, and simply say "No, thank you" when the security guards asked for one's identification? The criminals would celebrate, and we'd all be utterly alarmed. We would immediately be afraid for our personal safety. more

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

Valuing IP Addresses

The prospect of exhaustion of the IPv4 address space is not a surprise. We've been anticipating this situation since at least 1990. But it's a "lumpy" form of exhaustion. It's not the case that the scarcity pressures for IP addresses are evidently to the same level in every part of the Internet. It's not the case that every single address is being used by an active device. A couple of decades ago we thought that an address utilisation ratio of 10% (where, for example, a block of 256 addresses would be used in a network with some 25 addressed devices) was a great achievement.  more
