Why We’ll Never Replace SMTP

An acquaintance asked whether there's been any progress in the oft-rumored project to come up with a more secure replacement for SMTP. Answer: No. Truly, spam isn't a technical problem, it's a social one. If we could figure out some way to make mail recipient networks and hosts willing to shun known bad actors, even at the cost of losing some real mail for a while until the bad actors cave, it would make vastly more difference than any possible technical changes. more

Escalating War in Yemen Dividing Country’s Internet

"The latest development in Yemen's long-running civil war is playing out in the global routing table," Doug Madory reports in a blog post today from Oracle's Internet Intelligence unit. more

AXIS - The Fulcrum of Africa’s Internet Success

The Internet Society (ISOC) has been working with the African Union (AU) to facilitate the African Internet Exchange System (AXIS). This AXIS project funded by the EU-Africa Infrastructure Trust Fund and the Government of Luxembourg will help keep Internet traffic in Africa internal to the continent and avoid expensive international transit costs and delay latency in routing Internet traffic through other continents. more

Another Day, Another Set of Hacking Attacks. News At 11.

While reading Reuters I came across a news article indicating that a number of high profile agencies - from the United Nations to the Canadian Government to government of Taiwan - were broken into over a period of the past five years. ... I'll say it right now, even though I haven't been briefed on it. It was China. more

Internet Society Partnering With Facebook to Develop Internet Exchange Points Throughout Africa

The Internet Society today announced that it is partnering with Facebook to develop Internet Exchange Points (IXP) throughout Africa. more

New Innovations in Free Space Optics

I read an article on the Finley Engineering blog that talks about new research with free-space optics. For those not familiar with the term, this means communication gear that communicates directly using light without any wires. The article talks about a Chinese team of scientists who have used light to transmit ultrahigh-definition video signals between high-rise buildings. more

Day 30: Kaminsky DNS Bug Disclosure

In a highly anticipated presentation, Internet security researcher Dan Kaminsky today gave details of the much talked about Domain Name System (DNS) vulnerability issue which has been intensely covered since it was publicly announced a month ago on Jul 8th. Although original plans entailed keeping the bug details undisclosed for 30 days in order to allow for necessary security patches to be implemented around the world, details of the bug were eventually leaked-and-confirmed 13 days after its public announcement. Even so, just hours ago in jam-packed ballroom during the Black Hat conference, Kaminsky delivered his 100-plus-slide presentation detailing the DNS flaw that, if exploited, could potentially "destroy the Web". more

Addressing 2010

It's January again, and being the start of another year, it's as good a time as any to look at the last 12 months and see what the Internet was up to in 2010. This is an update to the report prepared 12 months ago when looking at 2009, so lets see what has changed in the past 12 months in addressing the Internet, and look at how address allocation information can inform us of the changing nature of the network itself. more

IPv4: Business As Usual

This year, we expect that the RIPE NCC's pool of unallocated IPv4 addresses will reach the "last /8", meaning that we have 16,777,216 IPv4 addresses left in the available pool. At that point it will no longer be possible for RIPE NCC members to obtain the amount of IPv4 addresses they will require to expand their current and future networks. When we hit the last /8, the RIPE NCC will only be able to distribute IPv6 addresses and a one-off allocation of IPv4 address space... Has this caused a last minute rush? more

NANOGGING

There are many network operator group meetings being held these days. Even in the backwater of the South Pacific where I live there is now AUSNOG, and NZNOG is just next door in New Zealand. We now have MENOG in the Middle East and AFNOG in Africa. The original NOG was the North American Network Operators Group (NANOG), and they have the T-Shirts to prove it! NANOG meets three times a year, and I attended NANOG 41 in October 2007. NANOG meetings cover a broad variety of topics, from operational tools, measurement, and peering practices through to a commentary on the state of the Internet industry. Here are my impressions of the meeting. more

Why the 1# Vulnerability for Cyber Attacks Will Be Apathy

Everyone has heard of the cyber security attacks on Target (2013), Home Depot (2014), Neiman Marcus (2014), Sony Pictures (2014), and the United States' second-largest health insurer, Anthem (reported February 2015), but have you heard of the security breaches for Aaron Brothers, Evernote (denial of service attack), P.F. Chang's China Bistro, Community Health Services, Goodwill Industries, SuperValu, Bartell Hotels, Dairy Queen, U.S. Transportation Command contractors, and more. more

Why You Should Demand ‘Net Morality’ Instead of ‘Net Neutrality’

I have come to the conclusion that "net neutrality" is an ethical issue at heart, one about the appropriate constraint of unfair ISP power. Some people are (I pray unintentionally) on the wrong side of a now-clear moral divide. They are claiming to prevent harmful abuse of power, when in reality their actions create fresh harm. A central issue is one of technical competence to comment. If your beliefs are disconnected from how the world works, you cannot evaluate whether you are espousing something sensible or silly. more

Download Speeds of GSM and 3GSM Networks

ARCchart is selling a new report entitled Mobile Broadband Performance of Carrier Networks. I can't personally justify the purchase, but I notice this wonderful graph in their sample. ARCchart gave mobile users free speed test applications... more

Other Countries Beginning to Adopt China’s Unique Approach to an Isolated Internet Structure

While in most developed nations, foreign telecoms are interconnected with local and other international Internet exchanges, in China, there are no foreign carriers detected within china's borders. more

TeleGeography’s Interactive Submarine Cable Map Is a Fun and Fascinating View Into Infrastructure

Ever want to know where all the submarine cables are that provide part of the physical infrastructure of the Internet? Or which cities in the world have the most connectivity via submarine cables? (or which regions might be single points of failure?) In doing some research I stumbled across this excellent site from the folks at TeleGeography... It is a very well done and captivating (to me, anyway) view into where all the current and planned submarine cables are located. more
