LTE and Spectrum Stupidity

Mobile operators are counting on Long Term Evolution (LTE) technology to handle surging demand for mobile data access. But LTE developers made some poor choices, cutting spectral efficiency and thus driving up operator costs. LTE was envisioned as an all IP system, but the RF allocations follow the voice-centric approach of earlier generations. While LTE standards allow for either Frequency Division Duplexing (FDD) or Time Division Duplexing (TDD), all initial LTE equipment uses FDD. FDD requires two separate blocks of spectrum... more

Addressing 2014 - And Then There Were 2!

Time for another annual roundup from the world of IP addresses. What happened in 2014 and what is likely to happen in 2015? This is an update to the reports prepared at the same time in previous years. So lets 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. more

Survey Results Expose Widespread DNS Vulnerabilities

The Measurement Factory and Infoblox have announced results of a survey of more than 1.3 million Internet-connected, authoritative domain name system (DNS) servers around the globe. The results of the survey indicate that as many as 84 percent of Internet name servers could be vulnerable to pharming attacks, and that many exhibit other security and deployment-related vulnerabilities. The surveys consisted of several queries directed at each of a large set of external DNS servers to estimate the number of systems deployed today and determine specific configuration details. more

Lessons from the O2 Network Outage: The Real Cost of Manual Processes

More than 30 million people lost their data connectivity on December 6, 2018, in the United Kingdom as O2's network suffered from a nationwide service outage. Based on several reports, the incident was caused by a human error at Ericsson, the telecoms supplier responsible for operating certain parts of the O2 network. To compensate for the downtime and tarnished reputation, the O2 management is now reportedly seeking damages of up to a hundred million pounds from Ericsson. more

How Much Could Businesses and Consumers Save if .com Price Cap Benefits Were Passed On to Consumers?

Recently, a blogger whose website features posts and ads from domain speculators wondered what the cost of registering a .com domain name would be if somebody else ran the .com registry. But this blog post asks the more relevant question: "How much could businesses and consumers save if the benefit of .com price caps were passed along to consumers?" Now is a good time to focus on this question, since Verisign and the US Department of Commerce just amended their Cooperative Agreement to allow limited, regulated .com price increases. more

Trademark Owners Beware: Cybersquatting Spreads to Twitter

TechCrunch reports that its brand has been taken as a Twitter name, and that there is a landrush going on to get these names, which are already trading for money. The problem is so bad that a name brokerage, Tweexchange, has sprung up to get to facilitate sales. more

RIPE NCC Publishes Case Study of youtube.com Hijack

As you may be aware from recent news reports, traffic to the youtube.com website was 'hijacked' on a global scale on Sunday, 24 February 2008. The incident was a result of the unauthorised announcement of the prefix 208.65.153.0/24 and caused the popular video sharing website to become unreachable from most, if not all, of the Internet. The RIPE NCC conducted an analysis into how this incident was seen and tracked by the RIPE NCC's Routing Information Service (RIS) and has published a case study... more

Welcome to Notflix! Your Streaming-Free ISP with the Best Quality of Experience!

It has been widely taken as "obvious" that a "no blocking" rule for ISPs is a good regulatory policy. Is this really the case? Does it save consumers from harm... or cause harm? Netflix has reached the point of being well over 30% of Internet traffic at peak time for some ISPs. This places three costs on the ISP and its users... So for someone who isn't a streaming video user, they are paying a share of the direct costs. more

The Demand and Supply Imbalance in Telecoms

You can't open a newspaper today, listen to the radio, or watch TV without hearing about the enormous explosion in the use of telecommunications technology - be it fixed or mobile broadband, the internet, social media, smartphones, tablets, wearables, IoT, cloud computing, the list is endless... Yet, at the same time, many telcos and ISPs are struggling to maintain their profitability. This defies economic logic. more

Considering Existing gTLDs: The .museum Top-Level Domain’s Potential

We keep talking about new gTLDs but, what about those generic Top-Level Domains which already exist and which no one talks about anymore? ...I am also familiar with the existing speech which says: "Check the .museum : it is the example why new gTLDs won't work". I think it has nothing to do with the fact that new gTLDs will or will not work. I strongly believe .museum has potential and I also think the actual situation of the .museum can change. more

Knowing Less

The announcement yesterday morning in the Times that New York State AG Andrew Cuomo had reached an agreement with three US network operators (Verizon, Sprint, and Time Warner) about blocking child pornography was both less and more important than it appeared. It's less important in that part of the agreement covers something ISPs already do... more

IPv6 DNS Blacklists Reconsidered

I opined about a year ago that DNS blacklists wouldn't work for mail that runs over IPv6 rather than IPv4. The reason is that IPv6 has such a huge range of addresses that spammers can easily send every message from a unique IP address, which means that recipient systems will fire off a unique set of DNSBL queries for every message... Now I'm much less sure this will be a problem... more

IP Network Transformation: Waiting Costs More Than You Think

Few CSPs would dispute that IP-based mobile communications are the future. But some still see little reason to replace TDM switches that, on the surface, cost them little beyond energy and housing expenses. At the recent Neustar Interactive Insights Summit, telecommunications experts Jennifer Pigg, Vice President at Yankee Group, outlined the conundrum -- and revealed the cost of doing nothing is higher than many think. more

The ITU and IPv6 Transition: Controversy at the IGF

At today's "Managing Critical Internet Resources" session of the Internet Governance Forum 2009, the ITU agenda on taking a role in IPv6 distribution once again reared its ugly head. In a heated exchange, Professor Dr Sureswaran Ramadass, the Director of Nav6 an ITU consultant/fanboy squared off with the new ICANN CEO about competition in IPv6 address distribution. more

.google Before Christmas

I'm a real fan of the Google Masterplan since its publication in 2005. After the introduction of its own global DNS I thought it might be a good idea to have a second look on the G-Masterplan. What I found is astonishing and shows the steps to .google. more
