I've come up with a fairly simple concept which I call "critical mass". In other words, it is appropriate to have special measures like a fee waiver up until IPv6 reaches critical mass. So how do I define critical mass. It is the point at which a significant number of IPv6 LIRs have achieved a significant deployment of IPv6. This now raises the question as to what is a significant number of LIRs and what is "significant deployment". I define these as simple numbers and I do not claim that my suggested numbers are definitive. Others may feel that they should be adjusted up or down. In any case, here are my suggested numbers. IPv6 has reached critical mass in the ARIN region when 300 LIRs have each deployed more than 100 /48s. Note that this measure only counts the LIRs that have deployed a significant number of /48s, in other words this is a subset of all LIRs in the ARIN region. I don't know whether or not this should be enshrined in policy but it may be of use for the board to consider this approach when they discuss extending the IPv6 fee waiver. ------------------------------------------------------- Michael Dillon Capacity Planning, Prescot St., London, UK Mobile: +44 7900 823 672 Internet: michael.dillon at radianz.com Phone: +44 20 7650 9493 Fax: +44 20 7650 9030
