How Did IPv6 Come About, Anyway?

This is a special two-part series article providing a distinct and critical perspective on Internet Protocol Version 6 (IPv6) and the underlying realities of its deployment. The first part gives a closer look at how IPv6 came about and the second part exposes the myths.

In January 1983, the Advanced Research Projects Agency Network (ARPANET) experienced a "flag day," and the Network Control Protocol, NCP, was turned off, and TCP/IP was turned on. Although there are, no doubt, some who would like to see a similar flag day where the world turns off its use of IPv4 and switches over to IPv6, such a scenario is a wild-eyed fantasy. Obviously, the Internet is now way too big for coordinated flag days. The transition of IPv6 into a mainstream deployed technology for the global Internet will take some years, and for many there is still a lingering doubt that it will happen at all. more

Is the Internet Dying?

There are indications that the Internet, at least the Internet as we know it today, is dying. I am always amazed, and appalled, when I fire up a packet monitor and watch the continuous flow of useless junk that arrives at my demarcation routers' interfaces. That background traffic has increased to the point where it makes noticeable lines on my MRTG graphs. And I have little reason for optimism that this increase will cease. Quite the contrary, I find more reason to be pessimistic and believe that this background noise will become a Niagara-like roar that drowns the usability of the Internet. And the net has very long memory... more

Summit to Focus on Knowledge Sharing for IPv6 Deployment

The IPv6 Forum, the North American IPv6 Task Force, and Charmed Technology, Inc. today announced that the U.S. IPv6 Summit 2003 will be held December 8 - 11, 2003 in Arlington, VA, at the Doubletree Crystal City. The U.S. IPv6 Summit 2003 will focus on deployment, technical depth of key IPv6 features, and applications or services of Internet Protocol version 6 (IPv6).  more

On the Upcoming Hearings on ICANN by the US Senate

I was a witness at the two prior hearing, one in 2001 and another in 2002 - it's quite an experience.

My submission to this year's hearing is online at http://www.cavebear.com/rw/senate-july-31-2003.htm

What's going to be said by the witnesses? I don't know. But I have some guesses... more

U.S. Senate’s Hearing on ICANN

Later today, Senator Conrad Burns, who chairs the U.S. Senate subcommittee responsible for supervising ICANN, will be holding a hearing on a number of issues.

At the beginning of the year, a press release called "Burns Unveils NexGenTen Agenda For Communications Reform and Security in the 21st Century", had reported:

"U.S. Sen. Conrad Burns (R-Mont.) announced his top priorities for his chairmanship of the Senate Communications Subcommittee during the 108th legislative session. The ten items, called the Burns NexGenTen Tech Agenda, aim to strengthen security and usher reform for 21st Century Communication... more

Moving Target: Spammer Using Over 1000 Home Computers as DNS

Some individual appears to have hijacked more than a 1,000 home computers starting in late June or early July and has been installing a new Trojan Horse program on them. The Trojan allows this person to run a number of small websites on the hijacked home computers. These websites consists of only a few web pages and apparently produce income by directing sign-ups to for-pay porn websites through affiliate programs. Spam emails messages get visitors to come to the small websites.

To make it more difficult for these websites to be shut down, a single home computer is used for only 10 minutes to host a site. After 10 minutes, the IP address of the website is changed to a different home computer... more

Juniper’s IPv6 Advocate Tests Mythology

IPv6 advocacy has been tainted by FUD and half-truth. CommsWorld recently interviewed Juniper's Jeff Doyle, who is a strong supporter of IPv6 -- but who also has little patience for IPv6 mythology. Forget security, half-true address crises and QoS: the best reason for the world to run with IPv6 is what's driven the Internet all along -- innovationmore

Fight Spam With the DNS, Not the CIA

It seems like spam is in the news every day lately, and frankly, some of the proposed solutions seem either completely hare-brained or worse than the problem itself. I'd like to reiterate a relatively modest proposal I first made over a year ago: Require legitimate DNS MX records for all outbound email servers.

MX records are one component of a domain's Domain Name System (DNS) information. They identify IP addresses that accept inbound email for a particular domain name. To get mail to, say, linux.com, a mail server picks an MX record from linux.com's DNS information and attempts to deliver the mail to that IP address. If the delivery fails because a server is out of action, the delivering server may work through the domain's MX records until it finds a server that can accept the mail. Without at least one MX record, mail cannot be delivered to a domain.

Internet Governance: There Are No Masterplans

Please pardon me if I start this story by telling about an incident that happened to me at the Madrid airport while flying to the ICANN meetings in Rio.

It was about midnight when, after flying in from Turin, my hometown, I had to go through the passport control to reach my gate for the flight to Rio. The war between the US/UK and Iraq had started two days before, and even if the Spanish government was among its supporters, security checks were apparently proceeding as usual. Passport controls inside the EU for EU citizens usually take a few seconds, and the line ahead of me was proceeding quickly. more

Brownian Motion And ICANN’s Latest Status Report To The United States

Brownian motion is the ceaseless random movement of particles suspended in a warm fluid. The particles move because they are buffeted by random collisions with molecules and atoms speeding this way and that under the impetus of heat. The greater the heat, the greater the motion. But no matter how much motion and how much heat, Brownian motion brings no progress.

Today I learned from Bret Fausett's ICANN Blog that ICANN has just published its Sixth Status Report Under ICANN/US Government Memorandum of Understanding, dated March 31, 2003. This report is subtitled "Report by ICANN to United States Department of Commerce Re: Progress Toward Objectives of Memorandum of Understanding" (emphasis added.) more
