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 = resolve_host;
Example: Custom resolver
let client = from_url_with_hostname.unwrap;
let addr = client.resolve_host;
CLI Usage
dnsoverhttps
comes with a small CLI utility providing host
functionality to resolve hostnames:

example.com has address 93.184.216.34
