Painting Ourselves Into a Corner with Path MTU Discovery

In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more

Cloud Computing Can Make You More Secure

The number one concern cited for avoiding cloud computing is security. And there is a reason for that. Cloud providers have demonstrated some spectacular failures in the past, including Amazon's near total shutdown of an entire region, Dropbox's authentication snafu, and innumerous cloud providers that go belly-up. However, in the long run, cloud computing is destined to become more secure than in-house IT. I will briefly describe two dynamics in the industry that point in that direction, with substantiating evidence. more

Quintett Leads Net Mundial Initiative (NMI): New Steam for an Enabling Multistakeholder Platform

At June 30, 2015 the Inaugural Meeting of the Coordination Council of the NetMundial Initiative (NMI.CC) elected a "Quintett" to guide its activities through the global Internet Governance Ecosystem. Alibaba's CEO Jack Ma from China, ICANN's President Fadi Chehade, Brazilian's Minister Virgilio Almeida and two woman: Eileen Donahou from Human Rights Watch (HRW)) and Marilia Maciel from the Center of Technology and Society (CTS) in Rio de Janeiro are sharing now the helm to bring more steam to this new innovative multistakeholder platform. more

Business Case for IPv6 - Part 1

When discussing IPv6, it is easy to forget that we are ultimately talking about an enhanced version of an existing network protocol. Sure, it brings about a number of technical advantages. But when viewed in isolation - without a business case - there really are not that many drivers that would place IPv6 on the agenda of the top decision makers looking after budgets. For IPv6 to gain serious momentum, this has to be changed. more

The Long Gestation and Afterlife of New gTLDs

ICANN continues to flail, pointlessly. The latest in a series of missteps that could easily have been avoided is its recommendations on what to do about a report on the potential for confusion and misaddressing when someone's internal network names match the name for a new gTLD, and they have misconfigured their routers and/or DNS to the extent that someone typing in a new gTLD name might end up in the middle of someone else's network. more

Bruce Schneier to Speak About Internet Surveillance at IETF 88 Technical Plenary Next Week

How do we harden the Internet against the kinds of pervasive monitoring and surveillance that has been in recent news? While full solutions may require political and legal actions, are there technical improvements that can be made to underlying Internet infrastructure? As discussed by IETF Chair Jari Arkko in a recent post on the IETF blog, "Plenary on Internet Hardening", the Technical Plenary at next weeks IETF 88 meeting in Vancouver, BC, Canada, will focus on this incredibly critical issue. more

U.S. Uses Domain Names As New Way to Regulate the Net

Governments have long sought ways to regulate Internet activity, whether for the purposes of taxation, content regulation, or the application of national laws. Effective regulatory measures have often proven elusive, however, since, unlike the Internet, national laws typically end at the border. Earlier this month, the United States began to move aggressively toward a new way of confronting the Internet's jurisdictional limitations - the domain name system. more

A Look Back at the Pandemic and What Was Missed in the ISPs’ Broadband Performance Reports

I was looking back at industry reporting a year ago after the impact of the pandemic first hit our broadband networks. Almost every big ISP issued press releases talking about how well it had weathered the pandemic and bragged about the resiliency of its networks. It turns out that these ISP press releases largely missed the point. They are right that their networks didn't crash, but once we understood the nature of the changes in broadband traffic due to the pandemic, that wasn't a big surprise. more

DNSSEC Adds Value?

The recent news that .uk, .arpa and .org may sign their zones sometime this year is indeed good news. Each domain is highly significant... As the DNSSEC registry infrastructure moves inexorably forward -- primarily driven by top level pressure and considerations of National Interest -- it now behoves us to clearly articulate the benefits of DNSSEC to domain owners and registrars. In particular I want to focus on the vast majority of us to whom cold, hard cash is important and parting with it requires as a minimum tangible benefits or, in extreme cases, surgical intervention. more

ARIN Elects First Board Member from the Caribbean

Regenie Fräser, the former Secretary General of a regional trade association, has been selected to serve a one-year term on the board of trustees of the American Registry of Internet Numbers (ARIN). Fraser's appointment makes her the first person from the Caribbean and the first non-white person to serve on the ARIN board. ARIN is one of five registries worldwide that coordinate Internet number resources. more

Absolutely No Wireless Spectrum Shortage in 2010

Sure the iPhone has problems, but John Stankey of AT&T thinks restoring a $2B capex cut will fix them. It may take a little more money than that, but Glen Campbell of Merrill Lynch has confirmed he's on track. In a 50 page report that's one of the best I've read in years, Merrill destroyed the common belief that wireless has a significant spectrum shortage. more

Speculation and Investment in Domain Names

There has been an ongoing debate on domain name blogs about the relationship between investment and speculation, but there has been no attempt to clarify and reconcile different views. In this essay, I shed some light on the relationship and analyze the implied value creation of transactions in the secondary markets. more

The Bright Side of Decentralized Domain Names

With solution providers such as Unstoppable Domains or Handshake, and blockchain technology-friendly browsers, such as Brave, that are more than happy to assist on the implementation front, decentralized alternatives to the traditional Domain Name System has been receiving more and more attention lately. Centralized vs. decentralized... what will it be? more

Internet Governance: The Issue, The Myths, The Problems, The Solutions

I have written a short paper on the topic of Internet Governance. Since it includes a number of resources, it would be easier for me to just point to a link with the document itself. Below are some selected excerpts from the document. "Several myths have been spreading around the World Summit on the Information Society (WSIS), but especially after the first Internet Governance Forum (IGF): The critical Internet resources (CIR) consist only of the IP addresses and the domain name system... There are only 13 root servers..." more

Who Are the Major New gTLD Applicants and… (Part Three: Minds + Machines)

Minds + Machines was the first "new gTLD portfolio applicant" I spotted early in 2008, when .PARIS started being mentioned. Then came a few other projects like .HORSE and later .VODKA. Being French, my vision of good new gTLD suffixes may be slightly different to those native English speakers. Therefore, I favour some TLDs such as .SURF and .ART over some clearly English terms others such as .HORSE. more
