[Doh] New tool for using and testing DOH

[Ben Schwartz <[e-mail]>]

Hi DOH,

(No chair hat)

My colleagues and I have been trying to make it easier to experience DNS
over HTTPS, and determine how well it performs in real-world usage.  To
that end, I’m pleased to announce Intra, an experimental DNS over HTTPS
client app for Android.  Intra routes all DNS queries on your Android
device through a DOH server of your choice. (Currently only dns.google.com
or cloudflare-dns.com, but I expect we’ll eventually figure out a way to
let you add your own).

App: https://play.google.com/store/apps/details?id=app.intra
Source code: https://github.com/jigsaw-code/intra

Intra currently uses Google’s pre-standard version of DOH with
dns.google.com, and uses draft-ietf-doh-dns-over-https with
cloudflare-dns.com.

Let me know if you have questions or feedback about the app.
