Hi All,

My name is Qinwen(Steven) Hu from the University of Auckland. I am
working on my PhD thesis in which I am trying to observe potential new
security issues in IPv6 networks. I have two questions I would like to
ask network operators:

1) Recently, we did a survey to investigate how network administrators
   are actually allocating IPv6 Interface IDs around the world.
   Our results show that 82% of domains use sequential small integer
   values in the interface ID field for their IPv6 addresses. 

   - What IPv6 address allocation mechanisms do you (or will you) use 
     in your IPv6 network/services? could you please give us your            reasons for using these mechanisms?

2) What new security issues, i.e. issues that don't exist in IPv4, do
   you think are likely to arise?

Steven
