I have received escalations in the last few days on my eyeball network regarding internet servers with 6to4 in DNS and NAT64 WKP in DNS. In the WKP case, the server operator read the RFCs and tried to pursued me to his understanding of those RFCs that i should route and support WKP to my NAT64 and that he was doing the right thing by putting the WKP as RR in his DNS files.
