Dnstls NPM | npm.io

dnstls

dnstls is a Node.js DNS over TLS command line tool. Here's a blog post that explains how it works.

Installation:

$ npm i -g dnstls

Usage:

Usage: dnstls name [type] [class] [@server] [-p<port>] [+tls-host=<host>]

If only name (domain name) is provided, it defaults to using Cloudflare's DNS-over-TLS server (@1.1.1.1 +tls-host=cloudflare-dns.com).

Example

$ dnstls sagi.io

Output:

    },
    {

      "data": "151.101.65.195"
    }
  ],
  "authorities": [],
  "additionals": []
}

Probably some time the future we'll add a DiG-like output.
