There seems to be a heated debate on this site about NAT (network-address translation). What came as a surprise to me is that a lot of the arguments seem to reside in ideological point of views which obscure the real issues at hand -- IP addressing, IP security -- and have little to do with NAT's actual merits or drawbacks. more
Erica Wass is the editor and contributing author of the recently published book, "Addressing the World: National Identity and Internet Country Code Domains", (Rowman & Littlefield, October 2003). This book is an edited collection of original essays by domain name administrators, academics, journalists and lawyers that examine the connections between various cultures and the use and regulation of their country code domain names. This is the second part of a three-part series. "Congress and the President of the United States believed so much in the idea that the Internet needed a "safe zone" for children that they passed a law designating such a space. One year after its passage I sought to examine the development of the .kids.us name space. I found an initiative that has yet to live up to its potential, but has a limitless, albeit difficult future ahead." more
Sonia Arrison, a director of the Center for Technology Studies at the California-based non-profit Pacific Research Institute, writes an interesting op-ed piece in the Internet news publication CNET News.com. She argues that the job of privatizing the domain name system should be completed and that market forces should control registry services such as SiteFinder deployed by VeriSign for about three weeks in September...While not a position I would agree with, as I would prefer more government control and additional regulation, it is definitely insightful and well written. She makes some interesting quotes... more
If you analyze the relay of spam- and malware-containing email circulating on the Internet purely through your mail server logs (running the Unix command "tail"), a large proportion seem to come from Asia Pacific hosts, especially those from mainland China. Therefore, many less-experienced systems administrators have simply blocked the access from subnets of Chinese or Asian origin, effectively destroying the fabric of the Internet -- messaging. If administrators took pains to analyze these supposedly Asian spam messages by analyzing the full Internet headers, they would have realized that the Asian servers were merely used by the real spammers as open relays, or perhaps as zombie hosts previously infected with the mass mailing worms through the exploitation of operating system vulnerabilities. more
Mark Jeftovic of easyDNS Technologies Inc. has posted an item on ICANN's "GNSO" registrars' mailing list titled "unsanctioned Whois concepts". In that item he suggests that the control and actual publication of contact information about a domain be put into the zone file itself, a file maintained by the registrant (purchasor) of the domain name. more
ICANN today has made a formal demand stating: "Given the magnitude of the issues that have been raised, and their potential impact on the security and stability of the Internet, the DNS and the .com and .net top level domains, VeriSign must suspend the changes to the .com and .net top-level domains introduced on 15 September 2003 by 6:00 PM PDT on 4 October 2003. Failure to comply with this demand by that time will leave ICANN with no choice but to seek promptly to enforce VeriSign's contractual obligations." What follows is a collection of commentaries made around the net and by experts in response to today's announcement...

I just discovered that VeriSign's SiteFinder Web site is leaking data submitted in Web forms to its marketing analysis partner, Omniture. Forms can easily contain personal information such as an email address. For the problem to occur, a Web form must use the GET method. This data spill problem occurs if a Web page anywhere on the Internet submits a Web form to an action URL with a misspelled or expired domain name. Because of VeriSign's recent controversial changes to the DNS system, this form data is submitted to the SiteFinder Web site. more
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
Consider this scenario: you need a domain name for your site so you go to your favorite domain registrar's website and upon a quick search find that your third choice is actually available! You quickly pull your credit card and register the name. Everything is good and you can't wait to have your new domain start pointing to your site and represent your official email address. But not so fast -- some of the recent events are revealing that, these days, when you are registering a domain name there is one more critical thing you need to do: check under the hood! more
A Forever URL is one that never expires. You own it and needn't worry about forgetting to renew it. The term itself is inspired by the US Forever Stamps, which you can use even if the postal rate goes up. This article looks at the underlying mechanisms for linking such information and is aimed at a technical audience. The DNS isn't just about websites; it is fundamental to how we connect endpoints, be they websites, devices, documents etc. more
It's unclear what this means in the long run. Do bad actions and actors go undetected? Do we lose our visibility into network management? What is a "secure" network, and how do we secure it using traditional techniques of network perimeter traffic inspection when all the network traffic is opaque? If we can't see inside the DNS anymore, then how can we tell if (or when) the DNS has been captured by one or two digital behemoths? more
Recently ten Democratic Members of Congress wrote a letter to Alan Davidson, head of the NTIA, requesting that the "NTIA immediately cease the public disclosure of personal information about users of .US" country code top-level domain (ccTLD). This communication highlights a significant concern regarding domain registration data: the need to protect the privacy rights of Registrants. However, an equally significant concern regarding registration data was raised... more
On July 2, 2002, Damien Cave published an interview on Salon.com with John Gilmore, "original 'cypherpunk' and all-around Internet supergeek," titled "It's time for ICANN to go." In this wide-ranging interview, Gilmore -- an early employee of Sun Microsystems who also co-founded Cygnus Software (acquired by Red Hat) and was an early supporter of the Electronic Frontier Foundation and the Internet Society (ISOC) -- offered blunt insight and eye-opening historical detail... more
The domain name system is not the place to police speech. ICANN is legally bound not to act as the Internet's speech police, but its legal commitments are riddled with exceptions, and aspiring censors have already used those exceptions in harmful ways. This was one factor that made the failed takeover of the .ORG registry such a dangerous situation. But now, ICANN has an opportunity to curb this abuse and recommit to its narrow mission of keeping the DNS running... more
Back in September of 2020, ICANN CEO Göran Marby wrote a blog post discussing the implementation of "a common strategy for Internet governance (IG) and technical Internet governance (TIG)", raising the question of whether the ICANN org. intended to pursue this distinction moving forward, as debated in a previous article. This was proven to be the case during the 2020 IGF's Open Forum #44: "ICANN Open Forum - Technical Internet Governance", organized by ICANN itself... more
