Crate dnsoverhttps[−][src]
dnsoverhttps - D'oh!
Resolve hostnames by sending DNS queries over HTTPS.
It uses https://1.1.1.1
as the DNS resolver by default, hosted by Cloudflare.
According to Cloudflare it is a privacy-first consumer DNS service.
See https://1.1.1.1 for more information.
Based on https://tools.ietf.org/html/draft-ietf-doh-dns-over-https-07.
Drawbacks
- When specifing a URL, the hostname has to be specified as well for use in HTTP. The TLS Certificate received from the server is validated, but not checked for the correct hostname..
- Only handles A and AAAA records for now (IPv4 & IPv6, this implicitely handles CNAMES when they are resolved recursively)
Example: Default resolver
let addr = dnsoverhttps::resolve_host("example.com");
Example: Custom resolver
let client = dnsoverhttps::Client::from_url_with_hostname("https://172.217.21.110/experimental", "dns.google.com".to_string()).unwrap(); let addr = client.resolve_host("example.com");
