What happens when you open an email and allow it to display embedded images and pixels? You may expect the sender to learn that you've read the email, and which device you used to read it. But in a new paper we find that privacy risks of email tracking extend far beyond senders knowing when emails are viewed. Opening an email can trigger requests to tens of third parties, and many of these requests contain your email address. more
Sun, surf, and ... service operators? It's a match made in heaven! The Caribbean cable and telecommunications industry may not be large, but it is an important and fast-growing region. The recent Caribbean Cable & Telecommunications Association (CCTA) Annual Meeting in Puerto Rico threw the spotlight on this slice of paradise and I was there to catch up on some of the trends emerging for the year ahead. more
It is openly admitted , in the same Implementation PDF file, that all accesses to the Site Finder service are monitored and archived. A further worry for users is the privacy policy and terms of service posted on the Site Finder service. Not only does the simple act of mistyping a URL implicitly cause you, the end user, to accept VeriSign's Terms of Service and Privacy Policy without the chance to review and accept or decline either, but critical information as described above is not disclosed in either policy (as of this writing). The Privacy Policy clearly states... more
I've often said that ICANN regulates the business of buying and selling of domain names and that ICANN's claim that it coordinates technical matters to preserve the stability of DNS is a fantasy. Well I am proven wrong. ICANN has done something technical. ICANN has issued Guidelines for the Implementation of Internationalized Domain Names, Draft Version 2 [PDF] (pending approval by the ICANN board.) It's only four pages long, but those few pages contain a lot of significant material. more
Engineers in the Internet Engineering Task Force, in the Messaging Anti-Abuse Working Group, and elsewhere have been debating how to handle e-mail-server blocklists in an IPv6 network. Let's take a look at the problem here. We basically have three ways to address spam, in our goal of reducing the amount of spam in our inboxes... more
"Breaking the Internet" is really hard to do. The network of networks is decentralized, resilient and has no Single Point Of Failure. That was the paradigm of the first few decades of Internet history, and most people involved in Internet Governance still carry that model around in their heads. Unfortunately, that is changing and changing rapidly due to misguided government intervention. more
ICANN 54 is upon us, and to commemorate it, we've got www.dublin.pub loaded up with friendly places to network, take advantage of the city's comedy and music scene, and possibly even enjoy a pint. With so many issues to discuss and address this week, a .PUB address wouldn't be the appropriate destination for the entire conference, but for a microsite discussing the cultural and social opportunities that Dublin has to offer, we happen to think it's perfect, especially in the place that gave the world the Irish pub. more
During a speech last week at the Internet Governance Forum in Bali, Jari Arkko, IETF's chair, re-emphasized it's efforts to ramp up online security in light of recent revelations of mass internet surveillance. "Perhaps the notion that internet is by default insecure needs to change," Arkko said. Significant technical fixes "just might be possible." more
The early designers of the Internet quickly realized that as the number of domain names flourished, there was a need for tracking domain name owners to resolve questions and conflicts that might arise. To that end, they created WHOIS, a public database with the names, phone numbers, email addresses, and mailing addresses of registered domain owners and operators. more
There are updates in the domain name business that I have never been able to understand: one of them is called "vanity domain names". A vanity domain name is a domain that keeps on using the first and the second level domain, to form a keyword; the third level domain is sometimes used too. Good examples of these would be: webc.am or marmala.de, aud.it or del.icio.us. more
Internet Society has released a paper today highlighting the importance of understanding what is important and unchanging about the Internet. more
In the 2014 Istanbul-Turkey IGF workshop on policies to promote broadband access in developing countries organised by Rui ZHONG of ISOC China, we realized that while technological solutions are advancing rapidly, policy and regulations remain a significant barrier to affordable internet especially in the developing world. According to a report by Alliance for Affordable Internet ( A4AI), the key to affordability is the policy and regulatory environment that shapes the different actors in the market. more
There are discussions starting within the Regional Internet Registries (RIRs) about the creation of trading market in IPv4 addresses as we approach the inevitable exhaustion of unallocated addresses. The view being put forward is basically "this is likely to happen anyway and by discussing it now, we can ensure it happens in an orderly way". When I first heard this idea I was a bit surprised. The RIRs are policy based bodies and so a shift to a trading market appears to be an abandonment of that policy base. However I have been partly corrected on that. more
In its latest quarterly report, McAfee Labs has reported seeing an average of 480 new threats per minute and a sharp increase in malware targeting IoT devices. more
There has been a lot of recent discussions and questions about reputation, content and delivery of email. I started to answer some of them, and then realized there weren't any basic reference documents I could refer to when explaining the interaction. So I decided to write some. This post is about IP address reputation with some background on why IPs are so important and why ISPs focus so heavily on the sending IP. more
