About

dnslookup is a small Node.js module to perform asynchronous DNS queries (A, AAAA, CNAME, MX, TXT, etc.) with a built-in cache.

It is intended for integration into scripts, microservices, and networking tools where reliable and performant DNS resolution is required.

Features

• Asynchronous DNS queries based on dns/promises with robust error handling.
• Configurable TTL cache.
• Multi-type support (A, AAAA, MX, TXT, CNAME, etc.).
• JSON-friendly output suitable for APIs.

Installation

npm install @octarahq/dnslookup

Usage

Basic example:

import { DNSLookup } from "@octarahq/dnslookup";

const dns = new DNSLookup();

// Simple A record lookup
const result = await dns.resolve("example.com", "A");
console.log(result);
// => [{ address: '93.184.216.34', ttl: 300 }]
