IPv6 Deployment: Just Where Are We?

In this article we'd like to look at some measures of the use of IPv4 and IPv6 protocols in today's Internet and see if we can draw any conclusions about just how far down the track we are with the IPv6 part of dual stack deployment. We'll use a number of measurements that have been made consistently since 1 January 2004 to the present, where we can distinguish between the relative levels of IPv4 and IPv6 use in various ways. more

IDN Parody on verisign.com

Guilllaume Rischard setup a parody on verisign.com using the IDN spoofing trick. He managed to get one registrar to register verisign.com with a cyrillic S (U+0405) (ie xn--veriign-mog.com :-) This actually started in #joiito a couple of weeks ago after the Eric published the spoofing attack paper. A joke was made that it would be funny if someone did it to verisign.com and so he did. I suppose I could rant why VeriSign should adopt the JET Guideline (or ICANN Guidelines) but this parody would send a louder message. more

Should the Government Prepare a Preemptive Cyber-Attack?

The House Committee on Science recently held a hearing to "examine the extent of U.S. vulnerability to cyber attacks on critical infrastructure such as utility systems, and what the federal government and private sector are doing, and should be doing, to prevent and prepare for such attacks." Specific issues addressed at the hearing included whether: 1) the U.S. is able to detect, respond to, and recover from cyber-attacks on critical infrastructure; and 2) is there a clear line of responsibility within the federal government to deal with cybersecurity... more

Moving Telephone Numbers Into the Internet Age

Now that we're 20 years past TN 2.0, well into the 21st century, and onto the 3rd generation of the web; it is about time we move telephone numbers into the Internet age. They are still managed as if they all connect to four copper wires. We manage to the lowest common denominator rather than acknowledging the power of mobility and Internet technology. more

Internet.nl - A New Site to Easily Test Your Use of IPv6, DNSSEC, TLS and DKIM

"Is Your Internet Up-To-Date?" Does your existing Internet connection work with IPv6 and DNSSEC? Do your web sites support IPv6, DNSSEC and TLS? Is there a quick way to find out? Earlier this month a new site, Internet.nl, was launched to make this all easy for anyone to test. All you do is visit the site at en.internet.nl (also available in Dutch) and just follow the very easy links. more

Independence and Security Online Have Not Yet Been Won

As we, here in the United States celebrate our independence this Fourth of July, we are reminded that the liberties and freedoms that come with that independence have yet to be won online. As citizens of this country we are blessed with safety and security from threats both foreign and domestic, but those guarantees have not yet extended to our citizenship in the global Internet community. This is true not just for American citizens, but for all Internet users throughout the world. more

IPv6 Security Myth #8: It Supports IPv6

Most of our IPv6 Security Myths are general notions, often passed on unwittingly between colleagues, friends, conference attendees, and others. Today's myth is one that most often comes specifically from your vendors or suppliers. Whether it's a hardware manufacturer, software developer, or Internet Service Provider (ISP), this myth is all about trust, but verify. more

ICANN Investigating Domain Tasting

ICANN has announced that it is seeking input and feedback on the topic of domain tasting. (See their announcement for full details) Interestingly enough Michael Gilmour published an article a couple of days ago covering the same topic - "Why domain tasting is great!", which will probably raise a few hackles! One point that in particular caught my eye... more

Three Things TLD Registries Must Know About China’s Domain Name Regulation

Recently there have been a number of news reports/articles that are incorrect or misleading in interpreting China's domain name management policy. James has posted an article aiming to clarify what is going to in China's domain name market. Considering the potential negative impact of those reports on the participants of this market, I supplement James's post by pointing out three things, which I believe critical for any TLD registries that hope to have a better understand of China's domain name regulation and the special action based on it. more

A Quick Primer on Internet Peering and Settlements

The business world today features many complex global service activities which involve multiple interconnected service providers. Customers normally expect to execute a single paid transaction with one service provider, but many service providers may assist in the delivery of the service. These contributory service providers seek compensation for their efforts from the initial provider. However, within a system of interdependent providers a service provider may undertake both roles of primary and contributory provider, depending on the context of each individual customer transaction. more

ICANN Gets the Root Zone, Too

A small but intriguing paragraph in the VeriSign settlement says that ICANN gets to maintain the root zone. I thought they did now, but I guess VRSN does, following advice from ICANN. This has two and a half effects. The most obvious is political -- if ICANN rather than VRSN is distributing the root zone, it removes the symbolic significance of VeriSign's A root server. The second is DNSSEC key management. Until now, the contents of the root zone have been pretty boring, a list of names and IP addresses of name servers. If DNSSEC is deployed in the root, which is not unlikely in the next few months, ICANN rather than VeriSign will hold the crypto keys used to sign the root zone. If a tug of war develops, whoever holds the keys wins, since without the keys, you can't publish a new version of the root with changed or added records unless you publish your own competing set of keys and can persuade people to use them. more

Revisiting Apple and IPv6

A few weeks ago I wrote about Apple's IPv6 announcements at the Apple Developers Conference. While I thought that in IPv6 terms Apple gets it, the story was not complete and there were a number of aspects of Apple's systems that were not quite there with IPv6. So I gave them a 7/10 for their IPv6 efforts. Time to reassess that score in the light of a few recent posts from Apple. more

IETF Publishes RFCs on SPF and Sender ID

A recent press release from the Internet Society reports that the IETF will shortly publish specifications of SPF and Sender-ID in the RFC series. What does this mean for the future? ...More than 4000 documents have been published in the RFC series since the first RFC in 1969, relatively few of which have evolved into Internet standards. Each RFC is characterized when published as standards-track, best current practice, informational, experimental, or historical. These four RFCs, three describing Sender ID and one describing SPF, are all experimental. more

Loudmouths Wanted for ICANN WHOIS Replacement Work

TL;DR? It's worth reading, BUT, if not -- ICANN has yet another group looking at WHOIS, and there is a huge push to redact it to nothing. I spend easily half my day in WHOIS data fighting online crime, losing it would not make my job harder, it will make it impossible. PLEASE JOIN THE ICANN GROUP and help us fight back against people who are fighting in favour of crime. more

IPv6 Security Myth #6: IPv6 is Too New to be Attacked

Here we are, half-way through this list of the top 10 IPv6 security myths! Welcome to myth #6. Since IPv6 is just now being deployed at any real scale on true production networks, some may think that the attackers have yet to catch up. As we learned in Myth #2, IPv6 was actually designed starting 15-20 years ago. While it didn't see widespread commercial adoption until the last several years, there has been plenty of time to develop at least a couple suites of test/attack tools. more
