Fine Grained Mail Filtering With IPv6

One of the hottest topics in the email biz these days (insofar as any topic is hot) is how we will deal with mail on IPv6 networks. On existing IPv4 networks, one of the most effective anti-spam techniques is DNSBLs, blackists (or blocklists) that list IP addresses that send only or mostly spam, or whose owners have stated that they shouldn't be sending mail at all. DNSBLs are among the cheapest of anti-spam techniques since they can be applied to incoming mail connections without having to receive or filter spam. more

Why Telcos Don’t Get Networks

I've posted to SSRN my paper on why most telecom companies, even though they operate networks, don't appreciate the fundamental business dynamics of network structures. This will be a chapter in a book Wharton is publishing on network-based strategies and competencies. In the paper, I describe two views on telecom and Internet infrastructure... more

A Look Back at the World of IP Addressing in 2020: What Changed and What It Means

Time for another annual roundup from the world of IP addresses. Let's see what has changed in the past 12 months in addressing the Internet and look at how IP address allocation information can inform us of the changing nature of the network itself. Back around 1992, the IETF gazed into their crystal ball and tried to understand how the Internet was going to evolve and what demands would be placed on the addressing system as part of the "IP Next Generation" study.  more

The Internet as Weapon

One of the most striking and enduring dichotomies in the conceptualization of electronic communication networks is summed up in the phrase "the Internet as weapon." With each passing day, it seems that the strident divergence plays in the press -- the latest being Tim's lament about his "web" vision being somehow perverted. The irony is that the three challenges he identified would have been better met if he had instead pursued a career at the Little Theatre of Geneva and let SGML proceed to be implemented on OSI internets rather than refactoring it as HTML to run on DARPA internets. more

Cyber Terrorism Is a Real Threat, and for the First Time Both Russia and the US Acknowledge It

Eugene Kaspersky, CEO and co-founder of Internet security giant Kaspersky Lab said last week that "terrorists could build a botnet that could bring down the entire Internet structure". Mr. Kaspersky ended his speech with the statement that "a global cyber police force, and global cooperation between law enforcement agencies and governments is needed". This goes very much in accordance with some of the conclusions in the Cyberspace Policy Review more

Missing in Action - ICANN’s 2010 Annual Report

In preparation for some upcoming long-haul international flights, I was looking for some "light" ICANN reading material. One document that came to mind was ICANN's 2010 Annual Report. Over the last four years ICANN has produced a year end report. While this document was probably originally conceived as a means to demonstrate ICANN's progress... more

Guadeloupe Moves to Set Up Internet Exchange Point

Developments in the Caribbean digital space are fuelling initiatives to strengthen the Internet infrastructure in the region. In Guadeloupe, a recent agreement among three Internet service providers has cleared the way for the island to establish its first Internet exchange point. Commonly called an IX or an IXP, an Internet exchange point is a critical element of Internet infrastructure used to interconnect networks and deliver data traffic between them. more

WIPO’s UDRP ‘Overview’ Gets Bigger (and Better)

Just as the number of domain names and domain name disputes have expanded significantly in recent years, so, too, has WIPO's "Overview," which has been updated to address the growing complexity of cases under the Uniform Domain Name Dispute Resolution Policy (UDRP). WIPO has just published the third edition of its "WIPO Overview of WIPO Panel Views on Selected UDRP Questions" -- commonly referred to as "WIPO Jurisprudential Overview 3.0." more

Telling the Truth About 5G

I still run across articles that extol the supposed wonders of 5G. The most recent, published in Gizmodo asks "How 5G Could Replace Your Home Broadband Connection". I was surprised to see an article like this in a tech-oriented site because the article gets most of the facts wrong about 5G - facts that are not hard to verify. This article talks about 5G having "faster download speeds, faster upload speeds, more bandwidth, and lower latency" than landline broadband. more

GeoTLDs: Diversity is Key

The 2004 new sTLD round brought about a new type of TLD in the form of .asia and .cat. As we always struggle for words to capture their nature, I call them "geoTLDs". Culture, language and ethnicity are also part of geography. Contrary to ccTLDs, geoTLDs do not have a territorial meaning. They are a wonderful addition to the Internet as they provide a way to demonstrate one's commitment to a community that is not defined by borders, yet linked to where the individual chooses to be. ...Will they be? They will, unless we do the wrong thing now. more

Next Generation gTLD Registration Directory Services (NG RDS) - Proposed Successor to WHOIS

The information in WHOIS database is very important to Law Enforcement Agencies, Intellectual Property Owners, and all Internet Users in general, who use this data to locate/contact domain name owners for various purposes including but not limited to enforcing laws or addressing grievances related to cybercrime and other cases of DNS abuse like Spam, Phishing, Malware etc. However, Privacy and Proxy Services are also available for many Top Level Domain Registries... more

ICC Cyber-Enabled Crimes and DNS Abuse: Accountability Questions for Infrastructure Operators

The ICC's new cyber policy reframes Internet infrastructure as crucial to prosecuting atrocities, prompting DNS operators and network providers to grapple with emerging obligations around evidence, neutrality, and cooperation in international justice. more

IPv6: The Summer It Finally Happened

A decade old guessing game finally came to an end during these 2012 summer months. America was supposed to be hopelessly behind while Europe had not much to show after a decade of spending lavishly EU money on IPv6 related projects. China and Japan were thought to be light years ahead of everybody else. But in the end, it was the might of the American Content Industry that tipped the scales. more

The Meeting That Changed the DARPA Datagram Internet

The National Science Foundation awarded a small contract to the IEEE to host a small two-day meeting on 30 Sept 1994 of selected invitees at the IEEE's Washington DC 18th Street offices on "Name Registration For The '.COM' Domain." Being part of the InterNIC contract oversight committee, I was one of the eight invitees. It turned out in many ways to be the single most important meeting in the long, checkered history of what is today referred to as "the internet," that made an extraordinarily bad decision. more

The Hack Will Be a Costly Affair for Optus

More and more information is becoming available about the breach of Optus (Australia's second-largest telco). It looks like the hacker is more of an amateur than a professional criminal or a "state actor." This makes the hack even more worrisome. It looks as though Optus didn't have its security house in order. This makes the issue all the more painful for the company. It will dent its reputation, and customers could become somewhat wary about dealing with the company. more
