Bringing Order to The World’s Cybrary: New TLDs Make Sense to Organize the Chaos of the Internet

There has been considerable debate on whether the Internet needs new Top Level Domains. Advertising advocacy groups have objected to the expense of re-investment in online branding. There's a lot of work involved in telling the world .BEYONCE is where you will now find all official Beyonce related information. I'm wondering, why would anyone object to some order being applied to the internet? more

Neustar Professional Services: Additional Expertise to Improve Productivity

While it would be nice if your company had IT staff members that were experts in every technology, that is just not realistic. And today, many companies face the challenge of finding the appropriate and specialized expertise that is required to deal with ongoing issues such as network optimization, performance degradations, network risks, and more. more

The Human Factor in DDoS Attacks

Ripped from the headlines: A recent DDoS attack lasted an entire 60 days. In other news, a single site was attacked 218 times in Q2 alone. To those of us in the business of protecting Web infrastructure, these stories are hardly surprising. What's notable, though, is where they were reported, in The Financial, whose focus is banking and financial services, not technology. The reporters used the term "DDoS" as if it were as common as "hedge fund," something everyday business people, not just techies, grasp. It's this human element that caught my interest and got me thinking a little. more

Recent Industry Changes: Internet Standards, ARIN WHOIS Changes, Hotmail Postmaster Pages

Signing Email is now a Draft Standard! Signing email transitioned from a proposed standard to a draft standard (RFC6376 -- one of the new RFCs) over at the IETF a few days ago. The other is RFC6377. Let's go through a brief history of DKIM RFCs to refresh our memories... more

The Design of the Domain Name System, Part VIII - Names Outside the DNS

In previous installments we've been looking at aspects of the design of the DNS. In today's grand finale we look at the the subtle but very knotty issue of names inside and outside the DNS. In the early years of the DNS, domain names were typically resolved to A records which were used to identify a host running a service. With the notable exception of e-mail, once the host was identified, the name no longer mattered. more

Hacking Away at the Internet’s Security

The front page story of the September 13 2011 issue of the International Herald Tribune said it all: "Iranian activists feel the chill as hacker taps into e-mails." The news story relates how a hacker has "sneaked into the computer systems of a security firm on the outskirts of Amsterdam" and then "created credentials that could allow someone to spy on Internet connections that appeared to be secure." According to this news report this incident punched a hole in an online security mechanism that is trusted by hundreds of millions of Internet users all over the network. more

TLD Domain Abuse: Threat Report - First Half 2011

When it comes to building a robust globe-spanning network of crimeware and making the victims dance to a tune of the cyber-criminals' choosing, you're guaranteed to find domain name abuse at the heart of the operation. DNS provides the critical flexibility and underlying scalability of modern command-and-control (C&C) infrastructure. Cyber-criminals that master DNS (and manage to maintain the stream of new domain registrations that keep it fed) tend to find themselves in command of the largest and most profitable crimeware networks. more

The Design of the Domain Name System, Part VII - Related Names Are Not Related

In previous installments we've been looking at aspects of the design of the DNS. Today we look at the relationship of similar names in the DNS. A poorly appreciated aspect of the DNS is that there is no inherent relationship between similar looking names. more

ICANN’s “Unelected” Crisis

The leaked release of the European Commission's working papers on the future of Top Level Domains highlights the impending collision between adherents of the present "multistakeholder" ICANN governance model, and an ever longer list of national governments who challenge that model. At the core of the controversy is the question of how ICANN can claim legitimacy in the DNS world when none of its Directors or Officers are elected. Even worse, its only answer, when challenged legally, is that it is responsive to its contract with an agency of the U.S. Government... more

The Design of the Domain Name System, Part VI - Overloaded Record Types

In the five previous exciting installments, we've been looking at aspects of the design of the DNS. Today we look at records types, and how you can tell what a DNS record means. All the records in the DNS are strongly typed. Each record includes an RRTYPE, a small number, which defines both the format of the record and what the record means. It is possible and common to have different record types with the same format, but different meanings. more
