After hearing over 350 presentations on IPv6 from IPv6-related events in the US (seven of them), China, Spain, Japan, and Australia, and having had over 3,000 discussions about IPv6 with over a thousand well-informed people in the IPv6 community, I have come to the conclusion that all parties, particularly the press, have done a terrible job of informing people about the bigger picture of IPv6, over the last decade, and that we need to achieve a new consensus that doesn't include so much common wisdom that is simply mythical. There are many others in a position to do this exercise better than I can, and I invite them to make a better list than mine, which follows. more
Many communications networks are constructed for a single form of communication, and are ill suited to being used for any other form. Although the Internet is also a specialized network in terms of supporting digital communications, its relatively unique flexibility lies in its ability to digitally encode a very diverse set of communications formats, and then support their interaction over the Internet. In this way many communications networks can be mapped into an Internet application and in so doing become just another distributed application overlayed on the Internet. From this admittedly Internet-centric perspective, voice is just another Internet application. And for the growing population of Voice over IP (VoIP) users, this is indeed the case... more
What economic and social factors are shaping our future needs and expectations for communications systems? This question was the theme of a joint National Science Foundation (NSF) and Organisation for Economic Co Operation and Development (OECD) workshop, held on the 31st January of this year. The approach taken for this workshop was to assemble a group of technologists, economists, industry, regulatory and political actors and ask each of them to consider a small set of specific questions related to a future Internet. Thankfully, this exercise was not just another search for the next "Killer App", nor a design exercise for IP version 7. It was a valuable opportunity to pause and reflect on some of the sins of omission in today's Internet and ask why, and reflect on some of the unintended consequences of the Internet and ask if they were truly unavoidable consequences... more
In March, I posted a call to action to those of us in the community who have the inclination to fight against a movement to redact information critical to anti-abuse research. Today, I felt compelled to react to some of the discussions on the ICANN discussion list dedicated to the issue of WHOIS reform: Sorry, not sorry: I work every working hour of the day to protect literally hundreds of millions of users from privacy violating spam, phish, malware, and support scams. more
You could call this Part Three in our series on Illicit Internet Pharmacy. Part One being What's Driving Spam and Domain Fraud? Illicit Drug Traffic, Part Two being Online Drug Traffic and Registrar Policy. There are a few facts I'd like to list briefly so everyone is up to speed. The largest chunk of online abuse at this time is related to illicit international drug traffic, mostly counterfeit and diverted pharmaceuticals. more
It's easy to look at Amazon SES and sigh. Thousands of low-end customers sending mail from a shared IP pool? Amazon already knows that trick never works! Just one spammer will ruin the reputation of those IP addresses, resulting in ongoing delivery problems for everyone who uses the service. It is possible that Amazon can build the systems and human processes to keep spammers out; certainly sounds like they want to. more
Spam these days is more than an annoyance -- it increasingly carries malware payloads that can do serious damage to your PC, steal your identity, or turn your PC into a zombie that carries out denial of service attacks. So anything that law enforcement can do to fight spam should be a good thing, right? Well, not quite, as I'll explain. more
We, as the Internet engineering community, have made a great mistake. Actually, it wasn't even one large mistake, but a series of small ones. Engineers are busy people, and most of us work under the constraints of the organizational entities we serve (be it ISPs, non-internet corporates, or even non-profits). Few of us have time for politics; even fewer have the desire and motivation for politics, and those of us who do try usually end up facing a brick wall of stubbornness, lack of understanding of the underlying technical issues, or just a deaf ear. more
The recent testing by Gmail of DomainKeys affords an opportunity to look again at what the impact of it may be in any attempt to introduce a Domino addin to verify DomainKeys signatures. I have here a sample of an email sent from Gmail and that same email after being delivered to the in-box of a Notes/Domino user who prefers MIME. There are differences which make DomainKeys a real problem at Domino shops (and, I suspect, others). more
Network operators rely on guidance from IP address experts because not all IP addresses used on the Internet are the same. The "reputation" of email senders is especially important because some are malicious users of the system. But identifying "senders" based on their email addresses or the individual IP address of a user presents issues that are unnecessarily complex. more
ICANN announced recently that it has begun negotiations with an applicant for another 'sponsored' (non-open) top level domain, .XXX. There has been a fair amount of coverage, for and against. My initial reaction is (with the proviso that the public information to assess these things is always insufficient): .XXX seems plausible for what it is but it isn't what many probably think it is. ...that's the key to understanding this. This TLD is intended to be a trade association and is not a form of regulation. more
In my roles as postmaster at CAUCE (the Coalition Against Unsolicited Commercial E-mail) and abuse.net, I get a lot of baffled and outraged mail from people who have discovered that someone is sending out spam, often pornographic spam, with their return address on the From: line. "How can they do that? How do I make them stop?'' The short answers are "easily'' and "it's nearly impossible.'' more
Sender Policy Framework (SPF) stops novice spammers but not the professionals, says Spammer-X, a retired spammer who has gone into a lot of the details in his book, "Inside the Spam Cartel". The best way to beat SPF is to join it... First, Joe Spammer rents a dedicated spam host in a spammer-friendly location, like China. Next, he registers 100 domain names, and each domain is registered under a fake name and address. Next, DNS entries for each of the hosts are set up, including a valid pointer record (PTR), an MX record and reverse DNS entries for each domain... more
Has your organization recently received an email claiming to be from NABP's Internet Drug Outlet Identification Program (IDOI)? If so, it is possible that someone is trying to trick you. The NABP IDOI team's email account has recently been illegally "spoofed" by unaffiliated persons or organizations. Email spoofing involves the forgery of an email header so that the email appears to have originated from someone other than the actual source. more
In the absence of any formal announcements, news of Google being accredited by ICANN as a domain name registrar, spread fast in the media today after it was first reported by Bret Fausett on Lextext -- see Google is a Registrar. The company has since mentioned that "Google became a domain name registrar to learn more about the Internet's domain name system," and that it has no plans to sell any domain names at the moment. However, speculations on what Google could do as an accredited registrar are far and wide. Here are ten, listed in no particular order... more
