This application provides registration information for domain names, IP addresses and autonomous system numbers, by reaching the autoritative RDAP servers and displaying the results. Displayed information includes registrant, expiration, registrar, registry, DNS servers and DNSSEC details, as well as contact information when available. As RDAP is being deployed by top-level domain registries, not all domain names may return data. RDAP is a replacement of Whois.
