I am no longer lecturing or supervising students. Potential graduate students: please don't waste your time sending me email. Instead, please see our research overview and our postgraduate options.

Three ways of looking at me (1997, 2005, 2009).
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. I am now an honorary professor.
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. Just now I am also working on autonomic networking.
IP version 4 has almost exhausted its address space, which is why we need IPv6. The world's central registry of IPv4 addresses emptied out in 2011, so all remaining spare addresses are in the hands of the various Regional Internet Registries. It is time for everyone providing network services to start adopting IP version 6 (IPv6). Use of IPv6 in the Internet is growing fast, and IPv6 works on all modern PCs and smartphones.
Click to test IPv6. If your service provider doesn't offer IPv6, complain!

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.
