One idea to make the problem of mail more manageable is to restrict the address space that is allowed to send mail. In an ideal world, we'd restrict where mail mail servers could send mail from. So, if we say that the number of individual mail servers in the world will probably never exceed 32 million (not unreasonable), or 2^25, then what if the 25 least significant bits were reserved for mail servers? more
We have seen that spammers already possess the ability to hop around IP addresses quickly. They do this because once an IP gets blocked, it is no longer useful to them. There are only so many places they can hide, though - 4.2 billion places they can hide. However, in IPv6, if they are able to do the same pattern of sending out mail and hopping around IP addresses the same way they do in IPv4, then there is virtually unlimited space they can hide in. more
Recently, a couple of anti-spam (or at least email security related) bloggers have written some articles about IPv6 and the challenges that the email industry faces regarding it. John Levine, who has written numerous RFCs and a couple of books about spam fighting, writes the following in his article "A Politically Incorrect Guide to IPv6, part III". more
One of the many Internet governance discussions currently taking place is at the CSTD Working Group on improvements to the IGF, which is due to have its second and final meeting on 24 and 25 March 2011. Despite an unpromising beginning, with only governments on the Working Group (WG), it is now a multi-stakeholder environment, with the technical, business and civil society represented at the WG and genuinely welcomed by governments to participate in the WG's deliberations. more
The natural disasters, climate change and widespread social and economic crises that are taking place in the world today show that the human race needs to become smarter. The urban revolution that succeeded the Neolithic agricultural revolution has allowed us to build new city-based civilisations that are conducive to innovation and information-gathering in all aspects of life and beyond. While amazing civilisations have come and gone over the last 10,000 years it is only since the 20th century that we have seen a real explosion in the urbanisation process, leading to a doubling of the global population. more
Less than nine months after the DNS root was signed, the rollout of DNSSEC across the Internet's top-level domains is approaching the tipping point. Thanks to the combined efforts of registries around the world, the new security protocol will soon be available to the majority of domain name registrants in almost a quarter of all TLDs. more
On Wednesday 16 March the Serious Organised Crime Agency organised a meeting in London with the RIPE NCC. For the second time law enforcers from the whole world met with the RIPE NCC and RIPE community representatives to discuss cooperation. RIPE NCC staged several very interesting presentations that showed the LEAs the importance of the work done within RIPE and ARIN, the information RIPE NCC has and the relevance of all this to LEAs. Also issues were addressed that can potentially be harmful to future investigations. more
At Friday's board meeting, ICANN once again narrowly approved the contentious .XXX domain intended for pornography. What this vote primarily shows is that ICANN's processes have been broken for a long time, and aren't getting fixed. Two board members made thoughtful and eloquent statements before the vote outlining the reasons they were about to vote for or against the domain. more
COICA (Combating Online Infringement and Counterfeits Act) is a legislative bill introduced in the United States Senate during 2010 that has been the topic of considerable debate. After my name was mentioned during some testimony before a Senate committee last year I dug into the details and I am alarmed. I wrote recently about interactions between DNS blocking and Secure DNS and in this article I will expand on the reasons why COICA as proposed last year should not be pursued further in any similar form. more
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
As a strong proponent of the private right of action for all Internet endpoints and users, I've long been aware of the costs in complexity and chaos of any kind of "blocking" that deliberately keeps something from working. I saw this as a founder at MAPS back in 1997 or so when we created the first RBL to put some distributed controls in place to prevent the transmission of unwanted e-mail from low reputation Internet addresses. What we saw was that in addition to the expected costs (to spammers) and benefits (to victims) of this new technology there were unintended costs to system and network operators whose diagnostic and repair work for problems related to e-mail delivery was made more complex because of the new consideration for every trouble ticket: "was this e-mail message blocked or on purpose?" more
Josh Baer, former VP of Datran Media and current CEO of OtherInBox has been floating an idea at the DMA's Email Experience Council and a few other places, and recently got some traction in Ken Magill's Magill Report. What Josh is proposing is to create the technical means by which a Sender can decide when email 'expires' and is automatically removed from a recipient's inbox, either by deletion, or perhaps archiving (in the case of Gmail). This would supposedly help the end-user, by removing marketing offers that are no longer available. Why this idea shouldn't happen... more
The 8.9-magnitude earthquake in Japan rocked the northeastern portion of the coast. The quake was the strongest to hit Japan in at least a century, sending a tsunami that flooded northern towns and also reached portions of the United States, including Hawaii. The quake was followed by a 7.1-magnitude aftershock. Impact on Internet connectivity... Japan’s Internet performance seemed to have emerged largely unscathed, but concerns continue for the telecommunications infrastructure as the country struggles to meet power demands in a state-of-emergency. more
When I see glib talk about the inevitable transition to IPv6 or DNSSEC, I have to wonder what industry people think they are working in. Let me give an example that has nothing to do with networking: storage capacity. Now if there is one constant that everyone in the computing industry can agree on it is that they expect storage media capacity to increase. more
Good news. In now my 15th ICANN meeting or so it's clear that the internet governance community is finally taking some real note of the rest of the world -- including the over 50% of humankind that doesn't use Latin script characters to communicate. In fact, talk of emerging markets is everywhere at the San Francisco ICANN meeting this week. The ICANN Board and Government Advisory Committee (or GAC, a group of government representatives that advise the Board) are talking about the needs of developing countries. more
