# DNS over HTTP client
A Perl module that provides DNS over HTTPS (DoH).
This is just a small module that I've built to discover the DNS over HTTPS protocol now that recently it has an RFC (at the time of writing): https://datatracker.ietf.org/doc/rfc8484/
This has not been published to CPAN, as it is just a small experiment to discover the protocol. PRs are welcome.
## Providers:
A list of DoH Providers (https://en.wikipedia.org/wiki/Public_recursive_name_server)
A first note: The first time I tried DNS over HTTP, I tried using 1.1.1.1 (CloudFlare's
public DNS) and 8.8.8.8 (Google's public DNS) on port 443. These IPs don't provide the
DNS over HTTPS service, although they do respond to HTTPS.
See the examples directory for DoH endpoints.
Here is the documentation for each provider:
CleanBrowsing
- Docu: https://cleanbrowsing.org/dnsoverhttps
- accepts the wire format as per RFC 8484
CloudFlare
- Docu: https://developers.cloudflare.com/1.1.1.1/dns-over-https/wireformat/
- accepts the wire format as per RFC 8484
Google
- Docu: https://developers.google.com/speed/public-dns/docs/doh
- Google didn't support RFC 8484 when the RFC was published, having a custom protocol. As of June 26, 2019, they started supporting RFC 8484 https://security.googleblog.com/2019/06/google-public-dns-over-https-doh.html
Quad9
- Docu: https://www.quad9.net/doh-quad9-dns-servers/
- accepts the wire format as per RFC 8484
OpenDNS / Cisco
- Docu: https://support.opendns.com/hc/en-us/articles/360038086532-Using-DNS-over-HTTPS-DoH-with-OpenDNS
- accepts the wire format as per RFC 8484
