Dear NANOG readers,
we are a team of researchers from ICSI Berkeley, TU Berlin, TU Munich,
Internet Initiative Japan and UC Berkeley jointly working on a project
to assess the effects of IPv4 address exhaustion.
As part of our research, we conduct a survey among network operators.
The goal of this survey is to better understand the degree of IPv4
scarcity that ISPs face and which measures are taken to combat it (IPv4
Carrier-Grade NAT deployment, IPv4 address markets, and IPv6 transition
If you work for an ISP that connects end-users to the Internet, we would
greatly appreciate your response.
