G root pmtu?
it seems that G root ops are blocking dns ops mail servers. the more i think about that the sicker i think some folk out there are. but anyway, anyone else seeing this kind of problem with g root? http://dnsviz.net/d/gn/dnssec/ whines gn/DS (alg 8, id 38486): No response was received until the UDP payload size was decreased, indicating that the server might be attempting to send a payload that exceeds the path maximum transmission unit (PMTU) size.

Re: CGNAT
With a ~59% dual-stack percentage and a 8% ds-lite percentage (aka 67% of our subscriber base has IPv6), we get around 40% of IPv6 traffic. -- Tassos Radu-Adrian Feurdean wrote on 10/4/2017 1:11 μμ: > On Fri, Apr 7, 2017, at 20:03, Mikael Abrahamsson wrote: >> On Fri, 7 Apr 2017, Max Tulyev wrote: >> >>> BTW, does somebody check how implementing a native IPv6 decrease actual >>> load of CGNAT? >> Reports are that 30-50% of traffic will be IPv6 when you enable dual >> stack.

This would be traffic that will not traverse your CGNAT. My data on customers supposed to be 100% dual-stack (unless they explicitely disable IPv6 on their side, which some of them do) says 25% on best days. It used to be up to 35% in late 2015. For reason unknown, it was going slightly down during 2016, with a sudden extra decrease in january this year.
