Installation

v install fleximus.vdns
v install --git https://github.com/fleximus/vdns

Usage

To use vdns in order to run queries, you need to specify the resolver's IP address. Here in our example we make use of Cloudflare's public 1.1.1.1 resolver.

import fleximus.vdns

fn main() {
	resolver := '1.1.1.1:53'

	result := vdns.query(vdns.Query{
		domain:   'gmail.com'
		@type:    .mx
		resolver: resolver
	}) or { panic('Failed query') }

	for answer in result.answers {
		println('${answer.name} ${answer.class} ${answer.ttl} ${answer.@type} ${answer.record}')
	}
}

Custom Timeout

import fleximus.vdns
import time

result := vdns.query(vdns.Query{
	domain:   'example.com'
	resolver: '1.1.1.1:53'
	timeout:  2 * time.second
}) or { panic('Query timed out') }

This library is under development: Do NOT use in production!
