Domain Name Typosquatter Still Generating Millions

Ever visit cartoonneetwork.com? Adaptac.com? Check the URLs carefully, for these aren't the "real" sites operated by the Cartoon Network cable channel or by Adaptec, manufacturer of PC storage devices. Instead, these domains -- and some 5,000+ others -- were registered by a Mr. John Zuccarini. Read on to learn what he is up to and how he has gotten away with it. more

Cricket Liu Interviewed: DNS and BIND, 5th Edition

In follow-up to recent announcement on the release of the latest edition of the very popular DNS and BIND book -- often referred to as the bible of DNS -- CircleID has caught up with Cricket Liu, co-author and a world renowned authority on the Domain Name System. In this interview, Cricket Liu talks about emerging issues around DNS such as security and IPv6 support, and important new features such as internationalized domain names, ENUM (electronic numbering), and SPF (the Sender Policy Framework). "Cricket Liu: We're now seeing more frequent attacks against DNS infrastructure. ...Turns out that name servers are terrific amplifiers -- you can get an amplification factor of nearly 100x. These attacks have raised awareness of the vulnerability of Internet name servers, which is possibly the only positive result..." more

In Bad Taste

So-called domain tasting is one of the more unpleasant developments in the domain business in the past year. Domain speculators are registering millions of domains without paying for them, in a business model not unlike running a condiment business by visiting every fast food restaurant in town and scooping up all of the ketchup packets. Since 2003, the contract between ICANN and each unsponsored TLD registry (.biz, .com, .info, .net, .org, and .pro) has added an Add Grace Period (AGP) of five days during which a registrant can delete a newly registered domain and get a full refund. Although this provision was clearly intended to allow registrars to correct the occasional typo and spelling error in registrations, speculators realized that this allows them to try out any domain for five days for free... more

Wall Street Journal Article on Whois Privacy

Today's Wall Street Journal discusses the fight over Whois privacy. The article on the front page of the Marketplace section starts by discussing how the American Red Cross and eBay use the Whois database to track down scammers: "Last fall, in the wake of Hurricane Katrina, the American Red Cross used an Internet database called "Whois" that lists names and numbers of Web-site owners to shut down dozens of unauthorized Web sites that were soliciting money under the Red Cross logo. Online marketplace eBay Inc. says its investigators use Whois hundreds of times a day..." more

City Identifiers on the Net: A Closer Look

Cities are among the largest regional authorities and natural human communities we know. Of course there are countries like China, India or the USA which count some hundred million or even a billion inhabitants. But there are also countries with far less than 100,000 inhabitants, like Tuvalu, Andorra or Barbados. If city communities are ranked by the number of inhabitants as independent entities among country communities, cities like Tokyo, New York, Shanghai or London head the ranking because they have more citizens than many countries. London for instance has more inhabitants than the Netherlands, and Tokyo outpaces Canada in that respect. Interestingly, there are only around 400 cities worldwide with more than 1 million inhabitants... The following post will give an overview of how cities are being identified on the Internet via Top-Level Domains and the opportunities that lay ahead. more

Fight Spam With the DNS, Not the CIA

It seems like spam is in the news every day lately, and frankly, some of the proposed solutions seem either completely hare-brained or worse than the problem itself. I'd like to reiterate a relatively modest proposal I first made over a year ago: Require legitimate DNS MX records for all outbound email servers.

MX records are one component of a domain's Domain Name System (DNS) information. They identify IP addresses that accept inbound email for a particular domain name. To get mail to, say, linux.com, a mail server picks an MX record from linux.com's DNS information and attempts to deliver the mail to that IP address. If the delivery fails because a server is out of action, the delivering server may work through the domain's MX records until it finds a server that can accept the mail. Without at least one MX record, mail cannot be delivered to a domain.

Vint Cerf’s Keynote at Domain Roundtable

I had the pleasure of eating breakfast with Vint Cerf, chairman of ICANN's board and Chief Internet Evangelist at Google, prior to his keynote address this morning. It was great to discuss some of the issues domainers are facing with regards to registrar practices, expiring domains, etc. directly with Cerf. Cerf's keynote kept the crowd engaged. I've summarized the topics he covered... Some people have misunderstood Cerf's position with regards to adding new domains. He said he is not opposed to adding new TLDs. What he advocates, however, is having a solid rationale for adding new TLDs. Cerf believes the processes and outcomes of the first two rounds of TLD adds were not satisfactory... more

How Domain Name Traffic Testing/Tasting Works

Starting from an old article (dated July 21st, 2005) published at Computer Business Review, (and following a more recent entry on GoDaddy's Bob Parson's blog) I would like to touch a bit more on the topic of 'traffic testing' or 'traffic tasting' of domains. This topic has been discussed at ICANN meetings since last year and is also referred to by the name of 'add/delete' or 'add/drop' storms... more

.XXX as Proposed is Wrong for Families & Kids

On August 23rd, the Internet Governance Project posted a letter Opposing Political Intervention in the Internet's Core Technical Administrative Functions. I disagree. ICANN and Governments should get involved when it comes to protecting children online. Every effort should be made to make it SIMPLE for average parents to let their children run free online without the risk of running across pornography and adult material while doing so. Why continue to let pornographers run free and unchecked on the most exciting tool created in the history of mankind just because they got there first? more

California Frets about Goodmail Email

On Monday the 3rd, California state Senator Dean Flores held a hearing of the E-Commerce, Wireless Technology, and Consumer Driven Programming committee grandly titled AOL: You Have Certified Mail, Will Paid E-mail Lead to Separate, Unequal Systems or is it the Foolproof Answer to Spam?. The senator's office said they were very eager to have me there, to the extent they offered to fly me out from New York, so since I happened to be on the way home from ICANN in New Zealand that weekend, I took a detour through Sacramento. Sen. Florez conducted the hearing, with Sens. Escutia and Torlakson sitting in briefly. Unfortunately, Sen. Bowen, who is very well informed on these topics, wasn't there. There were five panels of speakers, and I got to lead off... more

.XXX Puzzle Pieces Start to Come Together: And the Picture is Ugly

Americans who worried about governments somehow "running" the Internet through the United Nations failed to see the Trojan Horses that were rolled into ICANN's structure in 1998: the Governmental "Advisory" Committee and the special US Government powers over ICANN. The attempt by the US Commerce Department to "recall" the delegation of .xxx to ICM Registry due to pressure from deluded right-wing groups in the US who think that it will add to pornography on the Internet is a major inflection point in the history of ICANN, and could represent the beginning of the end of its private sector/civil society based model of governance. more

IDN and Homographs Spoofing

There is a published spoofing attack using homographs IDN. By using a Cyrillic SMALL LETTER A (U+430), Securnia is able to pretend to be http://www.paypal.com/. Actually this is well-documented in RFC 3490 under the Security Consideration: "To help prevent confusion between characters that are visually similar, it is suggested that implementations provide visual indications where a domain name contains multiple scripts. Such mechanisms can also be used to show when a name contains a mixture of simplified and traditional Chinese characters, or to distinguish zero and one from O and l..." more

Putting Multiple Root Nameserver Issue to Rest

I am often asked what I think of multiple root nameserver systems -- sort of like the Public-Root or the Open Root Server Confederation (ORSC) pushed by others in the past years. Whenever some well meaning person asks me for multiple roots in DNS, I answer: "DNS is a distributed, coherent, autonomous, hierarchical database. It is defined to have a single root, and every one of the hundreds of millions of DNS-speaking devices worldwide has the single-root design assumptions built into it. It would theoretically be possible to design a new system that looked superficially..." more

Hypertext Mail Protocol (a.k.a. Stub Email): A Proposal

Back in the days of dial-up modems and transfer speeds measured in hundreds of bits per second, unwanted email messages were actually felt as a significant dent in our personal pocketbooks. As increases in transfer speeds outpaced increases in spam traffic, the hundreds of unwanted emails we received per week became more of a nuisance than a serious financial threat. Today sophisticated spam filters offered by all major email providers keep us from seeing hundreds of unwanted emails on a daily basis, and relatively infrequently allow unwanted messages to reach our coveted Inboxes. So, to some degree, the spam problem has been mitigated. But this "mitigation" requires multiple layers of protection and enormous amounts of continually-applied effort. more

Phishing: An Interesting Twist on a Common Scam

After Two Security Assessments I Must Be Secure, Right? Imagine you are the CIO of a national financial institution and you've recently deployed a state of the art online transaction service for your customers. To make sure your company's network perimeter is secure, you executed two external security assessments and penetration tests. When the final report came in, your company was given a clean bill of health. At first, you felt relieved, and confident in your security measures. Shortly thereafter, your relief turned to concern. ...Given you're skepticism, you decide to get one more opinion. ...And the results were less than pleasing. more
