One small addition. That's an our older tech report, and that link is now broken. The current version is TR-693, at http://www.isi.edu/publications/trpublic/files/tr-693.pdf (the old version is now http://www.isi.edu/publications/trpublic/files/tr-688.pdf for folks who want to wax nostolgic about where DNS-over-TCP and TLS was back in Feb. 2014 :-). -John _______________________________________________ dns-privacy mailing list [email protected] https://www.ietf.org/mailman/listinfo/dns-privacy
