6 Ways to Strengthen DNS Security

The domain name system (DNS) grew to prominence during the initial, innocent days of the internet. During that time, early internet users tended to work for government or education organizations where trust was assumed, and security was not even a consideration. Since the online community was small and the internet was sparsely used, the importance of DNS was not widely understood, and as a consequence, left undefended. more

IPv6: Don’t Forget About Your Switches!

When preparing a network for IPv6, I often hear network administrators say that their switches are agnostic and that there is no need to worry about them. Not so fast. Yes, LAN switches function mainly at layer 2 by forwarding Ethernet frames regardless of whether the packet inside is IPv4 or IPv6 (or even something else!) However, there are some functions on a switch that operate at layer 3 or higher. more

Reporting To God

"GOD, at least in the West, is often represented as a man with a flowing beard and sandals. Users of the Internet might be forgiven for feeling that nature is imitating art — for if the Net does have a god he is probably Jon Postel" (The Economist, Feb. 1997) David W. Maher, Senior Vice President, Law and Policy of Public Interest Registry (PIR) offers his reminiscence of the early days of the Internet and attempts made to restructure the Domain Name System — an article he has entitled 'Reporting to God'. more

Google revealed on its official blog today that it is handling an average of more than 70 billion requests per day on its free Public DNS service. According to VeriSign's latest public statistics, it is handling only an average of 59 billion DNS requests per day, less than that handled by Google. more

What Are the Connections to Identified Hafnium Malicious IP Addresses?

Cyber attackers are very skilled at infiltration. They'd find ways into a house through cracks and holes that the homeowner doesn't know about. Analogically speaking, that's what the new cyber attack group dubbed "Hafnium" did when they identified several zero-day Microsoft Exchange vulnerabilities to get into target networks. With thousands of users for every Microsoft Exchange server, the attack has far-reaching implications. First, it establishes the presence of a new threat actor group in town. What else could they be up to? more

Addressing Technical and Operational Needs with TechOps

In the ICANN realm, TechOps stands for Technical and Operations and its goal is to simplify processes, to find solutions, and to advise on technical and operational matters. There are three TechOps groups: The Registry, the Registrar and the joint Registry and Registrar, also known as Contracted Party House (CPH). How did we get there and what exactly are we doing? more

Who Uses Google’s Public DNS?

Much has been said about how Google uses the services they provide, including their mail service, their office productivity tools, file storage and similar services, as a means of gathering an accurate profile of each individual user of their services. The company has made a very successful business out of measuring users, and selling those metrics to advertisers. But can we measure Google as they undertake this activity? How many users avail themselves of their services? Perhaps that's a little ambitious at this stage, so maybe a slightly smaller scale may be better. Let's just look at one Google service. more

PIR’s Anti-Abuse Policy for .ORG Offers No Due Process for Innocent Domain Registrants

PIR, the registry operator for .org, has sent notices to registrars that it is implementing an anti-abuse policy that offers no due process for innocent domain registrants... While it's good intentioned, there is great potential for innocent domain registrants to suffer harm, given the lack of appropriate safeguards, the lack of precision and open-ended definition of "abuse", the sole discretion of the registry operator to delete domains, and the general lack of due process. more

About Those Root Servers

There is an interesting note on the ITU Strategy and Policy Unit Newslog about Root Servers, Anycast, DNSSEC, WGIG and WSIS about a presentation to ICANN's GAC. (The GAC website appears to be offline or inaccessible today.) The interesting sentence is this: Lack of formal relationship with root server operators is a public policy issue relevant to Internet governance. It is stated that this is "wrong" and "not a way to solve the issues about who edits the [root] zone file." Let's look at that lack of a formal relationship... more

Is Verisign a Monopoly? Does It Matter?

Senator Elizabeth Warren and Rep. Jerry Nadler recently wrote a letter complaining that VeriSign overcharges for .com domains due to its market power. They sent it to the Department of Justice and the National Telecommunications and Information Administration (NTIA). While you can make a reasonable case that the claim is true, two more interesting questions are "Why now?" and "Why bother?" more

Domain Name Theft, Fraud And Regulations

When it comes to domain name disputes, no domain name has captured more media attention than sex.com. Of course, disputes about sex often obtain a great deal of attention, and the sex.com domain name dispute can grab its share of headlines because the case involves sex, theft, declared bankruptcy, a once-thriving Internet porn business, and fraud, instead of the typical cybersquatting allegations. Indeed, this case is remarkable for its potential impact on the development of caselaw concerning whether there is a valid basis to assume that trademark interests should overwhelm all non-commercial interests in the use of domain names. The answer is no, but the caselaw to support that answer is in tension with cases that strongly imply a contrary conclusion. more

An Interview with the Lead Developer of SPF - Part II

CircleID recently interviewed Meng Weng Wong, the lead developer of Sender Policy Framework (SPF) and founder of Pobox.com. As one of the leading anti spam authentication schemes, SPF is used by companies such as AOL, Earthlink, SAP and supported by anti spam companies such as Sophos, Symantec, Brightmail, IronPort, Ciphertrust, MailArmory, MailFrontier, Roaring Penguin Software, and Communigate Pro. Last month, Microsoft announced its agreement to merge Caller ID, its own proposed anti spam authentication scheme, with SPF -- the joint standard is called 'Sender ID'. In this two-part interview, Meng Wong explains how SPF got started, where it is today and what could be expected in the future of email. more
