Indeed so. And making things _other_ than the Internet work better can be damaging to the Internet. It isn't always, but it's something we need to consider when evaluating proposals. I think it's worth documenting this option because there's a code reserved for it, but I think it's highly questionable whether it makes the internet better, because it encourages practices with DNS that wind up violating the expectations resolvers might have for consistency of zones and so on. See for instance my DISCUSS here: http://datatracker.ietf.org/doc/draft-ietf-cdni-framework/ballot/ This wound up opening up a huge can of worms about the various assumptions that CDNs make about how resolvers will process DNS records, how this mechanism interacts with DNSSEC, etc. These things are definitely worth documenting, because people are doing them. But whether they improve the internet is very much open for debate. The CDNI document specifies other ways of accomplishing the same thing that I think are much less fraught. _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
