BIND 9 Users Should Upgrade to Most Recent Version to Avoid Remote Exploit

A remote exploit in the BIND 9 DNS software could allow hackers to trigger excessive memory use, significantly impacting the performance of DNS and other services running on the same server. A flaw was recently discovered in the regular expression implementation used by the libdns library, which is part of the BIND package. The flaw enables a remote user to cause the 'named' process to consume excessive amounts of memory, eventually crashing the process and tying up server resources to the point at which the server becomes unresponsive. more

A Look Ahead to Fedora 19

Fedora 19 is the community-supported Linux distribution that is often used as a testing ground for features that eventually find their way into the Red Hat Enterprise Linux commercial distribution and its widely used noncommercial twin, CentOS. Both distributions are enormously popular on servers and so it's often instructive for sysadmins to keep an eye on what's happening with Fedora. more

The Pros and Cons of Vectoring

Vectoring is an extension of DSL technology that employs the coordination of line signals to reduce crosstalk levels to improve performance. It is based on the concept of noise cancellation: the technology analyses noise conditions on copper lines and creates a cancelling anti-noise signal. While data rates of up to 100Mb/s are achievable, as with all DSL-based services this is distance related: the maximum available bit rate is possible at a range of about 300-400 meters. more

One Year Later: Who’s Doing What With IPv6?

One year on from the World IPv6 Launch in June 2012, we wanted to see how much progress has been made towards the goal of global IPv6 deployment. Both APNIC and Google are carrying out measurements at the end user level, which show that around 1.29% (APNIC) and 1.48% (Google) of end users are capable of accessing the IPv6 Internet. Measurements taken from this time last year show 0.49% (APNIC) and 0.72% (Google), which means the amount of IPv6-enabled end users has more than doubled in the past 12 months. more

IPv6: Less Talk and More Walk

The sixth month of the year is both symbolic and historic for IPv6 and a good time to take stock and see how we've progressed. But instead of looking at the usual suspects of number of networks, number of users, number of websites, etc... on IPv6, let's look at some new trends to see what's happening. At gogo6 we've been measuring the "Buzz" of the IPv6 market every week over the last two and a half years. more

ICANN Auctions or Private Auctions?

By this time next year the allocation of the new Internet namespace will be complete. Several hundred contention sets, ranging from likely blockbusters like .WEB to somewhat less obvious money-makers like .UNICORN, will be decided by some method. One way to resolve contention is to form a joint venture... That works well when there are only two competitors and there's a good basis of trust, and it's a great solution because there are no losers. But if there are three or more competitors, or if you don't like and trust your prospective partner-to-be, this really isn't an option. more

The Rise of Cyrillic Domain Names

This week, on a cruise ship navigating Russia's Neva river, around 250 domain registrars and resellers are gathered for the RU-CENTER annual domain conference. RU-CENTER is the largest Russian registrar in a market that is dominated by three companies. RU-CENTER and competitor Reg.Ru both manage around 28% of domains registered in the country's national suffix... RU-CENTER is also a figurehead for Russia's drive to make Internet use more palatable for those who are not natural ASCII writers. more

The Company You Keep

This story started earlier this year, with a posting to the Australian network operators' mailing list, asking if anyone had more information about why the web site that was operated by an outfit called "Melbourne Free University" was inaccessible through a number of major Australian ISPs. When they asked their local ISP if there was some issue, they were informed that "this was due to an Australian government request, and could say no more about it." more

Moving Beyond Telephone Numbers - The Need for a Secure, Ubiquitous Application-Layer Identifier

Do "smart" parking meters really need phone numbers? Does every "smart meter" installed by electric utilities need a telephone number? Does every new car with a built-in navigation system need a phone number? Does every Amazon Kindle (and similar e-readers) really need its own phone number? In the absence of an alternative identifier, the answer seems to be a resounding "yes" to all of the above. more

Why Trademark Owners Should Think Twice Before Reclaiming Domains

A recent kerfuffle around Italian chocolate and confectionery producer Ferrero SpA and fan Sara Rosso is the latest example of how important it is for companies to consider carefully the domain and user names they decided to reclaim. Sometimes, enforcing trademark rights online can go really wrong, really quickly. In 2007, Ms. Rosso chose February 5 to be "World Nutella Day" - a time when "Nutella Lovers Unite for One Day!" She built a web presence around Nutella Day that included a nutelladay.com website. more

The Role of Trust in Determining a New TLD’s Business Success

Warren Buffet famously said, "It takes twenty years to build a reputation and five minutes to ruin it." Like it or not, every Top-Level Domain (TLD) is a brand in the eyes of the consumer. So, just how important is trust in the success of the new top-level-domains? I'm no branding expert, but I grasp that no brand, no matter how memorable, will fail to achieve its goals if it does not gain the public's trust. more

Multi-Layer Security Architecture - Importance of DNS Firewalls

In today's world with botnets, viruses and other nefarious applications that use DNS to further their harmful activities, outbound DNS security has been largely overlooked. As a part of multi-layer security architecture, a DNS Firewall should not be ignored. After serving as a consultant for multiple organizations, I have encountered many companies that allow all internal devices to send outbound DNS queries to external DNS servers - a practice that can lead to myriad problems. more

Are You Ready for the Launch of New gTLDs?

It seems as though the inevitable is now upon us, and though there are many that have wished this day never come, the launch of the first new gTLD registries is approaching. Now whether the first new gTLD registry will launch within the next few months or be delayed due to Advice from world governments remains to be seen. However, most companies with which I have spoken desperately need any extra time to prepare for the launch of new gTLDs. more

Liberty Reserve Now, Bitcoin Next?

The papers have been abuzz with the shutdown of Liberty Reserve, an online payments system, due to accusations of large scale money laundering via anonymous transactions. Many people have noted similarities between LR and Bitcoin and wonder whether Bitcoin is next. I doubt it, because with Bitcoin, nothing is anonymous. more
