...when we're starting to deploy yet another IPv6-only technology :) Hello all, as a fairly large ISP (for Greek standards at least), we've been affected by IPv4 exhaustion for quite some time now. A few years back we gave LW4o6 a go, as documented here https://ripe76.ripe.net/presentations/11-lw4o6-deployment-as6799.pdf . In the end, it did not work out very well. Quoting myself (from v6ops mailing list), the reasons behind that were: "In no particular order: 1. CPE (almost OK after ~2 years and god knows how many iterations) 2. lwaftr performance (worth noting the the lwaftr is implemented as a VNF 3. vendor's reluctance to continue (much needed) dev/ment because of *lack of interest from other ISPs* " Please take extra note of (3). In any case, being the optimists we are, and having supportive mgmt, we decided (once more) against burying ourselves deeper into CGN. This time we're going with MAP-E (which incidentally was our first choice), mainly because we understand it and our MAP BR vendor does too :) . So, as I already mentioned, we're just about to deploy it commercially. We've tested with 2 CPE vendors sucessfully and we're just ironing out some provisioning details before launching. Deployment will be gradual of course and very very cautious. Unofficially, we are aware of a couple of similar trials from other ISPs and we'd love to hear about people who have already deployed such technologies (IPv6-only with IPv4aas) or are thinking about doing so. After all, that is exactly what this WG is about :) thanks for reading, Yannis
