So, which public resolvers have DNS-over-TLS? Cisco OpenDNS uses the<br>
non-standard DNScrypt and, for the others (Google, Verisign,<br>
Yandex...), I find nothing. Isn't it time to push them to add this<br>
feature?<br>

Another way to ask is: how can we encourage some/many of the public resolvers to do so? Is there someone on this list from the part of Verisign that runs 64.6.64.6 or from Comodo 8.26.56.26? It could look very forward-looking of a public resolver to do this, for example.</blockquote><div><br></div><div><div class="gmail_default" style="font-size:small">There are two issues, both of which I brought up at the start of DPRIV:</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">1) Must be supported by browsers.</div><div class="gmail_default" style="font-size:small">2) Protocol MUST be entirely state free</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small">If you want a protocol to be deployed, you need to solicit input from the people who you need for deployment and take notice of it.
