Jean Camp [Indiana University Bloomington - School of Informatics]Abstract: In the near term there will be no available, unallocated IPv4addresses. From original estimates of IPv4 exhaustion in 2037, the mostwidely-cited current estimates for ARIN IPv4 address depletion is nowat 2013. This deadline gives a particular importance to IPv6 adoption.The goals of this work were to identify valid measures of IPv6diffusion and use classic diffusion models to bound the uncertainty inthose measures.
