Powerful RDAP lookups, simplified.
rdaptastic lets you query RDAP data quickly and intuitively, giving you structured, reliable information about domains, IP addresses, ASNs, and related entities – all in a clean, modern interface.
Run simple RDAP queries or explore deeper connections with click-through navigation. Jump directly from nameservers to their associated ASN and IP data, without re-entering queries or switching tools.
Go beyond standard RDAP results with augmented data. The app enriches registry information with additional context such as nameserver ASN and IP details, DNSSEC status, transfer lock state, and other relevant metadata, helping you better understand ownership, infrastructure, and security posture.
Designed for developers, network engineers, and internet professionals who need fast access to accurate registry data – whether for debugging, investigation, or everyday analysis.
