who-is-lookup 🌐

A modern, high-performance, dependency-free Node.js package designed to query domain, IP address, and ASN registration data using legacy WHOIS protocols and modern RESTful RDAP gateways.

🚀 Features

• Zero Dependencies: Pure vanilla Node.js architecture for blazing-fast execution.
• Dual Protocol Support: Handles legacy port-43 WHOIS text streams and RESTful JSON-based RDAP lookups.
• Granular RDAP Engines: Dedicated lookup wrappers for domain, asn, ipv4, and ipv6.

📦 Installation

npm install whois-rdap-node

🛠️ Usage Example

Here is a comprehensive script demonstrating how to import and orchestrate sequential queries across both the RDAP and WHOIS submodules.

import { rdap } from "whois-rdap-node";
import { whois } from "whois-rdap-node";

(async function main() {
   // 1. RDAP Domain Queries
   await rdap.domain("google.com");
   await rdap.domain("dovene.org");

   // 2. RDAP Autonomous System Number (ASN) Queries
   await rdap.asn(52224);
   await rdap.asn(262144);
   await rdap.asn(7467);
   await rdap.asn(2043);
   await rdap.asn(144698);

   // 3. RDAP Internet Protocol IP Queries (IPv4 / IPv6)
   await rdap.ipv4("8.8.8.8");
   await rdap.ipv4("202.12.29.1");

   await rdap.ipv6("2001:4860:4860::8888");
   await rdap.ipv6("2606:4700:4700::1111");
   await rdap.ipv6("2a00:1450:4009:820::200e");
   await rdap.ipv6("2001:dc0::1");

   // 4. Legacy Port-43 Fallback WHOIS Query
   await whois.lookup("dovene.org");
})();
