How can we track the amount of DNSSEC validation happening globally? Is there a way we can see the trend over time to (we hope!) see validation rise? At the recent excellent DNSSEC Workshop at ICANN 50 in London Geoff Huston let me know that his APNIC Labs team has now created this exact type of trend chart. more
In Tony Li's article on path MTU discovery we see this text: "The next attempt to solve the MTU problem has been Packetization Layer Path MTU Discovery (PLPMTUD). Rather than depending on ICMP messaging, in this approach, the transport layer depends on packet loss to determine that the packet was too big for the network. Heuristics are used to differentiate between MTU problems and congestion. Obviously, this technique is only practical for protocols where the source can determine that there has been packet loss. Unidirectional, unacknowledged transfers, typically using UDP, would not be able to use this mechanism. To date, PLPMTUD hasn't demonstrated a significant improvement in the situation." Tony's article is (as usual) quite readable and useful, but my specific concern here is DNS... more
As I mentioned in a post to the Deploy360 blog today, there are three excellent sessions relating to DNSSEC happening at ICANN 50 in London next week: DNSSEC For Everybody: A Beginner's Guide; DNSSEC Implementers Gathering; DNSSEC Workshop. Find out more. 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
Today the e-mail faerie brought news of the release of BIND9 9.10.0 which can be downloaded from here. BIND9 is the most popular name server on the Internet and has been ever since taking that title away from BIND8 which had a few years earlier taken it from BIND4. I used to work on BIND, and I founded ISC, the home of BIND, and even though I left ISC in July 2013 to launch a commercial security startup company, I remain a fan of both ISC and BIND. more
Keynote speaker, and noted security industry commentator, Bruce Schneier (Co3 Systems ) set the tone for the two days with a discussion on how humans name things and the shortcomings of computers in doing the same. Names require context, he observed, and "computers are really bad at this" because "everything defaults to global." Referring to the potential that new gTLDs could conflict with internal names in installed systems, he commented, "It would be great if we could go back 20 years and say 'Don't do that'," but concluded that policymakers have to work with DNS the way it is today. more
If you are interested in DNSSEC and how it can make the Internet more secure, the DNSSEC Workshop at ICANN 49 in Singapore will be streamed live for anyone to listen and view. One of three DNSSEC-related technical events at ICANN 49, the DNSSEC Workshop takes place on Wednesday, March 26, from 8:30am - 2:45pm Singapore time. more
Most people, even seasoned IT professionals, don't give DNS (the Domain Name System) the attention it deserves. As TCP/IP has become the dominant networking protocol, so has the use of DNS... Due to the reliability built into the fundamental RFC-based design of DNS, most IT professionals don't spend much time worrying about it. This can be a huge mistake! more
Here we are with CircleID's annual roundup of top ten most popular posts featured during 2013 (based on overall readership). Congratulations to all the participants whose posts reached top readership and best wishes to the entire community for 2014. more
This year, 2013, I got 24 days of IPv6 and DNSSEC measurements. All in all it created 15GB logs with more than 62 million rows. On the 21st of December, early in the morning, the goat was "traditionally" burnt down, however this year with one exception. Via the Swedish newspaper Expressen the arsonists anonymously took the blame and also filmed their own act. more
