That would mean until "forever", unless there is a flag day. It might be smarter and more flexible to devise a traffic sampling scheme to serve as input to a reoccurring review of the need for v4 service for a given zone. This also implies that the decision process could be distributed. (the various cases outlined above would of course be dealt with separately, but I suspect horisontal decision fragmentation (ie between namn.se and example.se) would take place as well.) > We should recommend that customers zones (4) be served under IPv4, but I > think it is a misstake to think that customers can rely on free > namesservers. Free nameserver service has limitations. I do not think that we should specify this either. We might advise, but what people ultimately use for serving their zones is their own problem, as long as they fulfill the requirements of their mother zone. -- Måns Nilsson Systems Specialist +46 70 681 7204 KTHNOC MN1334-RIPE
