Greylisting Still Works - Part I

Greylisting is a hoary technique for rejecting spam sent by botnets and other poorly written spamware. When a mail server receives an attempt to deliver mail from a hitherto unseen sending host IP address, it rejects the message with a "soft fail" error which tells the sender to try again later. Real mail software does try again, at which point you note that the host knows how to retry and you don't greylist mail from that IP again. more

Google’s Gigabit Gambit

Want a gig (1000 megabits per second) of Internet access bandwidth? Google says you could have it by the end of next year "from Manhattan to rural North Dakota (sic, I think they meant Vermont)" if their proposal to the FCC is accepted forthwith according to CNET's newsblog. Not only a gig but a mobile gig, accessible by cellphone or roaming computer -- no fiber required. Sound too good to be true? -- it isn't, IMHO! Engineering is not the problem... more

New CEO Stresses ICANN’s Role in Cybersecurity

One summer sport in Internet governance is speculating on what direction ICANN's new CEO will take it in. Making the media rounds yesterday on Fox and Lehrer News Hour to talk about the recent DDoS attacks on US and S. Korea government and commercial websites, new CEO Rod Beckstrom pushed how the response to cyber attacks is a coordinated effort, he also alluded to ICANN's role in similar attacks. Responding to a question on the News Hour about the USG policy response to dealing with cyber attacks, Beckstrom highlighted the critical role of ISP filtering, and identified the "organic" as well as "somewhat structured" coordination which occurs during a typical response. More interestingly, he plugged ICANN's facilitating role. more

Registrars That Complied With “Shakedown” Requests May Now Be in Violation of ICANN Transfers Policy

At the time we posted 'Whatever Happened To Due Process,' we were unaware that we were just one of many registrars receiving these notices from the London (UK) Police. We have since been made aware that this was part of a larger initiative against the BitTorrent space as a whole, and that most if not all of the other registrars in receipt of the same email as us folded rather quickly and acquiesced to the shakedown orders. more

The IANA Stewardship Transition - Now Is the Time to Share Your Views

The IANA Stewardship Transition process may have started more than a year ago, but last week it reached its pinnacle with the publication of the compiled Proposal to Transition the Stewardship of the Internet Assigned Numbers Authority (IANA) Functions from the US Commerce Department's National Telecommunications and Information Administration (NTIA) to the Global Multistakeholder Community" by the IANA Coordination Group (ICG). more

DMARC and Message Wrapping

I have groused at length about the damage that anti-phishing technique DMARC does to e-mail discussion lists. For at least two years list managers and list software developers have been trying to figure out what to do about it. The group that brought us DMARC is working on an un-DMARC-ing scheme called ARC, which will likely help somewhat, but ARC isn't ready yet, and due to ARC's complexity, it's likely that there will be many medium or small mail systems that enforce DMARC and can't or won't use ARC. more

Luddites of the 21St Century Unite?

In the past few weeks doom and gloom stories about the future were printed, discussed and opined in the press. The down and out of the message of futurists is that the middle class is going to be swept away in the coming years because of software and robotic solutions (from here on: automated processes), making humans redundant... Do Luddites of the 21st century need to rise? I want to look at the topic from a few angles. more

Email Portability, DKIM, and Socio-Political Implications on Tech Development

A few years ago, cell phone portability was introduced in the United States which caused a major shift in the market. The same thing happened this past year in Israel, following a major battle involving the cell carriers, consumer groups and the Israeli parliament (The Knesset). What if the same happened with email addresses? Ridiculous, you say? May be so, but there is chatter here in Israel to create a law which forces the local service providers hands to do just that. more

Some Random Notes from IETF 115

The IETF held its 115th meeting in London in November 2022. This was another in the set of hybrid meetings with specific support for online attendees in addition to the normal face-to-face meetings for the week. In no particular order, here are a few of my impressions from the IETF meeting. more

Google Fiber: Technology Innovation Or Revenue Assurance?

Google's announcement of its 'Fiberhoods' throughout Kansas City is yet another example of the thought leadership and innovation being brought forward by the popular advertising company. But what does this move say about the state of Internet access in America? more

IPv4 Market and IPv6 Deployment

IPv4.Global's Lee Howard will be a panelist at the Internet Governance Forum's session, "IGF 2020 WS #327 Believe it or not, the Internet Protocol is on Sale!" Preparing for this session has provided an opportunity to research how the IPv4 address market has affected the deployment of IPv6. There are a few spikes where a large number of addresses was transferred in a single transaction, most recently from APIDT.org. more

The Hybrid Cloud Impact on IPv6 Adaptation

Over the last couple of months, the enterprise computing space seems to have started a shift from private cloud paradigm into the hybrid cloud model. That makes sense, because the hybrid cloud allows companies to forgo the capital and the operating expenses associated with private clouds, in exchange for a pay-as-you-go model where you can just sit back and consume the business applications. more

Driving DNSSEC: The Need for Integration of All the Functions Needed

DNSSEC continues to gain momentum as network operators and domain owners watch and learn from early adopters. The learning process is made easier by efforts such as the ongoing work conducted by researchers at Sandia labs to methodically identify and categorize the kinds of problems that are occurring. more

Can Energetic Leadership Inspire ICANN?

ICANN CEO Fadi Chehadé was already 2 hours into his flight from Singapore to Paris when the pilot's voice interrupted the in-flight entertainment. A tech problem meant turning back, landing in Singapore, waiting for another plane and starting the long haul again! Half a day later, Chehadé landed in Paris. He'd already missed a lunch appointment but was still in time to make a reception organised at French ICANN board member Sébastien Bachollet's initiative. more

TV Everywhere: Dangers in Being Second to Over-The-Top Competitors

Time Warner Cable and Comcast's intent in creating TV Everywhere conjured up a cable TV presence on the Internet where customers could browse and view huge varieties of content by just being a customer. That seemed a fairly simple and innovative concept... It was unique 3 years ago and promised to be exclusive to their clientele. But in reality the concept is much different than the original vision cable operators promoted. more
