I am no longer lecturing. Potential research students: please see our postgraduate options.
For my University of Auckland profile including contact data and a short biography, look here.
Three ways of looking at me.
I joined the Computer Science department in Auckland in September 2007 and I was appointed Professor in January 2009. After retirement, I spent a year from April 2012 as an academic Visitor at the Computer Laboratory of Cambridge University, UK. In 2013 I came back to the University of Auckland part-time, mainly doing research consultancy.
My research interests are focussed on Internet infrastructure issues including routing and addressing. In recent years I have been active in Internet protocol design, mainly in the IETF. I am particularly interested in scaling issues and the much-needed deployment of IPv6. I'm also interested in related measurement issues, and to some extent in quality of service issues.
IP version 4 is quickly running out of address space, which is why we need IPv6. In fact, as of February 2011 the world's central registry of IPv4 addresses is essentially empty, and all remaining spare addresses are in the hands of the various Regional Internet Registries. It is time for everyone providing network services of any kind to be actively planning the adoption of IPv6.

Special note for IIT students: Every year, numerous IIT students send email asking about "summer internships". There is no budget to support such internships, and in any case during the summer in India, it's winter in New Zealand and we are busy with regular teaching. All such emails are deleted without being read.
