There are two categories of ISP subscribers:1. If subscriber is provisioned for IPv6, they are pointed at the ISP's DNS server which responds to AAAA normally -- 2. If subscriber is NOT provisioned for IPv6, they are pointed at the ISP's DNS server which responds to AAAA with an empty answer.
This proposal seems to have the right setup of defaults to work well now and to continue working well as the IPv4/v6 landscape changes. Moreover, as access to a recursive server is a _service_, I don't see how one can stop ISPs from doing this. DNS servers have never presented a uniform namespace (due to propagation of changes and later split DNS), though some ISPs respect the end-to-end principle more than others. On the downside I see this proposal moving us closer to a world where messing about with DNS end-to-end service by the network is seen as acceptable. -- Andras Salamon [email protected] _______________________________________________ DNSOP mailing list [email protected] https://www.ietf.org/mailman/listinfo/dnsop
