Syrian Internet Shutdown

James Cowie from Renesys reports: "Starting at 3:35 UTC today (6:35am local time), approximately two-thirds of all Syrian networks became unreachable from the global Internet. Over the course of roughly half an hour, the routes to 40 of 59 networks were withdrawn from the global routing table." more

DHCP for IPv4 vs. IPv6 - What You Need to Know

Dynamic Host Configuration Protocol (DHCP) is a protocol intended to enable machines (servers, game consols, etc) wishing to be "online" the ability to request Internet Protocol information from a DHCP server automatically. ... In this article we will begin to outline some of the fundamental differences between DHCPv4 and DHCPv6, explore historical uses of DHCPv4 and how those concepts will adapt/change in IPv6. more

Who Broke the WHOIS?

As Internet services go, WHOIS held a lot of promise but has repeatedly failed to live up to its potential; raising the question "is it time to retire WHOIS?" The concept behind WHOIS was simple. For each and every registered domain name, provide the facility for querying details about who owns it, who administers it, when was it created and when it will expire. Unfortunately the service lost its way practically from day one after failing to agree upon or adhere to any formal structure of the content it provides. more

ICANN Releases gTLD Applicant Guidebook

Per their timeline, ICANN released the gTLD Applicant Guidebook on May 30th. This version contains revisions based upon both community feedback, as well as recent consultations with the Governmental Advisory Committee (GAC). more

Solving the Spam Problem

Last week, I read Ed Falk's blog post where he commented on a possible solution to the spam problem. He himself was commenting on a study done by researchers out of the University of California where they discovered that credit card transactions for stuff bought in spamvertisements are handled by three companies: one in Azerbaijan, one in Denmark and one in the West Indies. Presumably, if security experts and law enforcement went after these companies, spammers would have their financial supply cut off. No money = no incentive to spam. more

Experts Urge Congress to Reject DNS Filtering from PROTECT IP Act, Serious Technical Concerns Raised

A group of leading DNS experts have released a paper detailing serious concerns over the proposed DNS filtering requirements included as part of the bill recently introduced in the U.S. Senate named Preventing Real Online Threats to Economic Creativity and Theft of Intellectual Property Act of 2011 ("PROTECT IP Act"). The group who is urging lawmakers to reconsider enacting such a mandate into law, includes leading DNS designers, operators, and researchers, responsible for numerous RFCs for DNS, publication of many peer-reviewed academic studies related to architecture and security of the DNS, and responsible for the operation of important DNS infrastructure on the Internet. more

University of California Identifies the Next Hard Target in a Never Ending War

This is, of course, about the recent NYT article that showcases the results of Prof Stefan Savage and his colleagues from UCSD/Berkeley. As my good friend and longtime volunteer at CAUCE, Ed Falk, points out, this is a great find, but hardly a FUSSP. The nice thing about the fight against bots and spammers is these little victories people on "our" side keep having in an endless series of skirmishes and battles... more

The User Experience with New TLDs: How to Avoid the Junk Mail File or ‘User Unknown’

As new Top-Level Domains (TLDs) are launched, the industry mustn't overlook the customer experience. A key question is this: Will the software applications we all use, recognize the new TLDs and know what to do with them in a timely fashion? Think email and even form-fill applications. I speak from experience here. In 2006 when we launched the .MOBI TLD, there were arguably only a handful of .MOBI email addresses in existence. To my dismay, I found that often emails sent only from my .MOBI account were not being received at the other end... more

Planning for the Ugly End of the Phone Network

Consumers who have a choice are quickly deciding they don't need the old copper-based phone network, often known as POTS for Plain Old Telephone Service. We use our cellphones for talking even when we're not mobile. The cell phones have built in phone directories, easy ways to return calls, the ability to call a number on a web page; and we don't share them with our parents or children... It's a good year for traditional phone companies when they don't lose more than 10% of their POTS lines. more

A True Final Ultimate Solution to the Spam Problem?

A common acronym in spam-fighting is FUSSP -- Final Ultimate Solution to the Spam Problem. It's used (usually derisively) to describe the latest proposed scheme to end spam once and for all. Usually these schemes are based on false assumptions or have already been tried with no results. This time - be still, my beating heart - it looks like some researchers at the University of California might really be on to something. more

Tucows Comments on ICANN Applicant Guidebook

The latest ICANN Applicant Guidebook was released in mid-April and covers the introduction of new generic Top Level Domains (gTLD). The introduction of new gTLDs has been an ongoing conversation for more than a decade. We have an opportunity to approve the final draft in time for consideration of the new gTLD implementation program during the ICANN Board meeting, which will be held on Monday, 20 June 2011, in Singapore. We submitted our comments yesterday and wanted to share them with you. more

Last Minute Surge of Opposition to VeriSign .NET Auto Renewal

The current .NET Registry Agreement between ICANN and VeriSign is due to expire on 30 June 2011. On April 11 2011 ICANN posted a proposed draft renewal agreement for public comment. Under the terms of the existing agreement, which contracted a 6 year term starting July 1 2005, renewal is automatic unless VeriSign commits some egregious breach of terms. more

How the End of IPv4 Affects Email and Hosting

Anyone who has been watching the technology industry for more than a couple of years quickly learns to recognize FUD: Fear, Uncertainty and Doubt. FUD is (apparently) widely believed to be an effective marketing technique, especially when it comes to security, privacy, or scarcity. But the FUD often falls flat. Scarcity, in particular, is rare on the internet -- even rarer than privacy or security. There's constant FUD about scarcity of bandwidth, but the pipes get upgraded. Attempts to impose artificial scarcity through paywalls or other devices inevitably fail in the face of free alternatives. Even the scarcity of IPv4 addresses, which have indeed run out at the top, hasn't affected end users at the bottom yet -- and probably won't, for a long time. more

IP Addresses as Money

It's no secret that the supply of IPv4 addresses, on which the Internet has been based since the dawn of digital time, is rapidly running out. The official replacement is much larger IPv6 addresses, but I can report from experience that the task of switching is not trivial, and for a long time there will be a lot of the net that's only on IPv4. So once the initial supply of IPv4 addresses run out, and the only way to get some is to buy them from someone else, what will the market be like? more

Facebook.com/Brand vs. a New TLD: What’s a Brand to Do?

Last week I published an article in Ad Age that the editors titled "Should your company jump on the dot-brand bandwagon?" I received several emails and LinkedIn requests from advertising and PR agencies as well as brand managers. One of the questions I received had to do with my opinion on whether brands that are currently promoting themselves via Facebook, e.g., "Find us on Facebook.com/brand," should consider the new Top-Level Domains (TLDs). more
