Why do we still need IPv4 when we are migrating to IPv6...

[Erik Kline]

> Appreciate your feedback, but as long as the majority of Norwegian content providers does not move on IPv6, including governmental sites, and the potential risk of the Norwegian government implementing some sort of Data Retention Directive, it makes sense to by addresses instead of doing CGN or equivalent.

Sure this potential Data Retention Directive will not be IPv6-specific
and somehow exempt IPv4?
