What Drives IPv6 Deployment?

May 2018

It’s been six years since World IPv6 Launch day on the 6th June 2012. In those six years we’ve managed to place ever increasing pressure on the dwindling pools of available IPv4 addresses, but we have still been unable to complete the transition to an all-IPv6 Internet. More...

 


Measuring ATR

April 2018

One of the more pressing and persistent problems today is the treatment of fragmented packets. We are seeing a very large number of end-to-end paths that no longer support the transmission of fragmented IP datagrams. What can the DNS do to mitigate this issue? More...

 


Measuring the Root Zone KSK Trust

April 2018

An analysis of DNS resolver data to attempt to estimate the impact of a roll of the KSK. More...

 


Stuffing the Camel into the Bike Shed

April 2018

I’m sure that there are folk who believe that bodies like the IETF can exercise just the right level of restraint and process management to keep excessive levels of both camelling and bikeshedding out of the IETF and its Working Groups activities. Speaking personally, I just can’t see that happening. More...

 


Just One Bit

March 2018

I'm never surprised by the ability of an IETF Working Group to obsess over what to any outside observer would appear to be a completely trivial matter. Even so, I was impressed to see a large-scale discussion emerge over a single bit in a transport protocol being standardized by the IETF. More...

 


DNS OARC 28

March 2018

March has seen the first of the DNS Operations, Analysis, and Research Center (OARC) workshops for the year, where two days where too much DNS is just not enough! More...

 


Crypto Zealots

March 2018

Is the IETF is behaving irresponsibly in attempting to place as much of the Internet’s protocols behind session level encryption as it possibly can? More...

 


Peak DNSSEC?

February 2018

Has the adoption of DNSSEC already peaked well before any level of complete deployment? If so that what might that mean for the way in which we manage security and resilience on the Internet? More...

 


Addressing 2017

January 2018

Time for another annual roundup from the world of IP addresses. Let’s see what has changed in the past 12 months in addressing the Internet and look at how IP address allocation information can inform us of the changing nature of the network itself. More...

 


BGP in 2017

January 2018

This is a report on the experience with the Internet's inter-domain routing system over the past year, looking in some detail at some metrics from the routing system that can show the essential shape and behaviour of the underlying interconnection fabric of the Internet. More...

 


A Workshop on Internet Economics

December 2017

In the United States the debate between advocates of market-based resolution of competitive tensions and regulatory intervention has seldom reached the fever pitch that we've seen over the vexed on-again off-again question of Net Neutrality in recent weeks. How can we assist and inform that debate? One way is to bring together the various facets of how we build, operate and use the Internet and look at these activities from a perspective of economics. This is the background to a relatively unique gathering, hosted each year by CAIDA, the Centre for Applied Internet Data Analysis, at the University of California, San Diego, at WIE, the Workshop on Internet Economics. These are my notes from the 8th such workshop, held in December 2017. More...

 


Network Neutrality - Again

December 2017

It strikes me as odd to see a developed and, by any reasonable standard, a prosperous economy getting into so much trouble with its public communications policy framework. More...

 


Helping Resolvers to help the DNS

November 2017

Here, I'd like to look at ways that recursive resolvers in the DNS can take some further steps that assist other parts of the DNS, notably the set of authoritative name servers, including root zone servers, to function more efficiently, and to mitigate some of the negative consequences if these authoritative name servers are exposed to damaging DOS attacks. More...

 


Hiding the DNS

November 2017

I’d like to look in a little more detail at the efforts to hide the DNS behind HTTPS, and put the work in the IETF's DOH Working Group into a broader perspective. There are a number of possible approaches here, and they can be classified according to the level of interaction between the DNS application and the underlying HTTPS encrypted session. More...
