DNS

Non-blocking extendable DNS client for crystal lang.

With built in support for UDP, TLS, HTTPS and mDNS resolvers

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     dns:
       github: spider-gazelle/dns
   

2. Run shards install

Usage

A simple query

require "dns"

responses = DNS.query(
  "www.google.com",
  [
    DNS::RecordCode::A,
    DNS::RecordCode::AAAA,
  ]
)

ips = responses.map(&.ip_address)

Configure for HTTPS DNS (secure from prying eyes)

require "dns"
require "dns/resolver/https"

DNS.default_resolver = DNS::Resolver::HTTPS.new(["https://1.1.1.1/dns-query"])

# or just for some routes
DNS.resolvers[/.+\.com\.au$/i] = DNS::Resolver::HTTPS.new(["https://1.1.1.1/dns-query"])

# there is a built in resolver to use mDNS for *.local routes
