Last year the municipality of Gavle asked my company if we could help them load share the streaming pictures of the famous Christmas goat in Gävle. I accepted the invitation and set up a separate domain. My own interest in this was of course to track the usage of IPv6 and validation of DNSSEC from the visitors of the site. more
The year 2010 is turning out to be the "year of DNSSEC" from Registry implementations, Registrar implementations, ISP support, to the Root being signed this summer. Because we are dealing with such critical infrastructure, it is important to not lose sight of careful implementations. more
One of the most interesting and important changes to the internet's domain name system (DNS) has been the introduction of the DNS Security Extensions (DNSSEC). These protocol extensions are designed to provide origin authentication for DNS data. In other words, when DNS data is digitally signed using DNSSEC, authenticity can be validated and any modifications detected. more
It is once again time for our annual review of posts that received the most attention on CircleID during the past year. Congratulations to all the 2018 participants for sharing their thoughts and making a difference in the industry. more
"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
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
As part of Verisign's ongoing effort to make global internet infrastructure more secure, stable, and resilient, we will soon make an important technology update to how we protect the top-level domains (TLDs) we operate. The vast majority of internet users won't notice any difference, but the update will support enhanced security for several Verisign-operated TLDs and pave the way for broader adoption and the next era of Domain Name System (DNS) security measures. more
The recent NANOG 61 meeting was a pretty typical NANOG meeting, with a plenary stream, some interest group sessions, and an ARIN Public Policy session. The meeting attracted some 898 registered attendees, which was the biggest NANOG to date. No doubt the 70 registrations from Microsoft helped in this number, as the location for NANOG 61 was in Bellevue, Washington State, but even so the interest in NANOG continues to grow... more
Earlier this week in a press release, VeriSign said that they are selling their SSL certificate business to Symantec. VeriSign is the dominant player in this market, having absorbed competitor Thawte in 1999, and Geotrust in 2006. Three years ago, when VeriSign decided to divest its non-core businesses, they kept the certificate business. So what's changed? more
FireEye announced a new piece of malware yesterday named MULTIGRAIN. This nasty piece of code steals data from Point of Sale (PoS) and transmits the stolen credit card numbers by embedding them into recursive DNS queries. While this was definitely a great catch by the FireEye team, the thing that bothers me here is how DNS is being used in these supposedly restrictive environments. more
The Mirai DDOS attack happened just over a year ago, on the 21st October 2016. The attack was certainly a major landmark regarding the sorry history of "landmark" DDOS attacks on the Internet. It's up there with the Morris Worm of 1988, Slammer of 2002, Sapphine/Slammer of 2009 and of course Conficker in 2008. What made the Mirai attack so special? more
Many of us were expecting radical changes in 2010 to the domain name market. There definitely were some of those -- just not the ones I expected. From the seizure of domains names by the US Government to ICANN's removal of restrictions on Registry/Registrar cross-ownership, 2010 was a year full of surprises. In this post, I've compiled what I think were the biggest domain name stories in 2010. more
Nearly 92 percent of malware use DNS to gain command and control, exfiltrate data or redirect traffic, according to Cisco's 2016 Annual Security Report. It warns that DNS is often a security "blind spot" as security teams and DNS experts typically work in different IT groups within a company and don't interact frequently. more
ICANN hosted a Resolver Operator Forum in mid-December, and the session had several interesting presentations that I would like to comment on here... The first presentation in this forum was from Paul Mockapetris. He pointed to the original academic published paper, Development of the Domain Name System, by Paul Mockapetris and Kevin Dunlap, published in the proceedings of ACM SIGCOMM’88. The paper noted that by 1983 it was obvious that the shared HOSTS.TXT file was not a scalable solution... more
Domain names are registered by the thousands every day. In July 2021, 236,336 domains were newly registered daily on average across all top-level domains (TLDs). Tens of thousands were also newly expired. Other months could be just as busy. "Newly registered" and "newly expired." Those are two terms I often get questions about. Newly registered domains are domains that someone just reserved, typically through a registrar or web hosting company. Newly expired domains, meanwhile, are those domains that someone had reserved but decided to let go for one reason or another. more
