Introducing yWhois: An Enhanced Tool for IP, Domain, and ASN Lookup with RDAP

In the ever-evolving landscape of internet infrastructure, having reliable tools for network resource lookup is essential. Today, I’m excited to introduce an updated version of yWhois—a comprehensive platform designed for IP, domain, and ASN information retrieval using RDAP protocols.

Since its initial launch last year, yWhois has undergone significant improvements to enhance performance and reliability. One notable challenge was managing rate limits during high traffic periods. To address this, I’ve integrated multiple worker servers, which should help distribute the load more effectively and ensure smoother operation even during busy times.

While it’s somewhat surprising that a registrar’s RDAP service enforces such restrictive API usage limits—especially considering RDAP is intended to serve as a modern, standardized alternative to traditional WHOIS—these constraints are a reality developers continually navigate. Nevertheless, I believe these updates will provide a more robust and consistent experience for users.
