Whois.ls is a next-generation domain lookup interface created by Mayo that supports WHOIS and RDAP queries for domains, IPv4 and IPv6 addresses, ASNs, and CIDR ranges. It uses an RDAP-first approach with a WHOIS fallback, delivering structured registration data through a modern, responsive UI and an open API endpoint for programmatic access.

Whois.ls is built for developers, researchers, and network professionals who need fast, readable domain and IP intelligence without the friction of older lookup interfaces.
