Use !rdap-dns to lookup registration data for an Internet DNS domain name.

The Domain Name System (DNS) maps human-readable DNS names to Internet Protocol (IP) numbers. DNS can also map one DNS label to another DNS label, such as through CNAME or DNAME records, allowing domain names to alias or redirect to other domain names. These mappings form the hierarchical structure of DNS resolution and enable flexible naming architectures across the Internet.

RDAP provides structured registration data for domain names, including registrar information, registry metadata, contact points, name servers, status codes, DNSSEC indicators, and domain lifecycle states.

Some domain registries and registrars do not yet support RDAP. For such domains, the legacy registration data lookup scheme can be used through !whois-dns, which queries traditional WHOIS servers when RDAP information is unavailable.

This command supports ASCII domain names, internationalized domain names (IDNs), and punycode-encoded labels. It can be used to inspect generic top-level domains (gTLDs), country-code top-level domains (ccTLDs), and specialized infrastructure domains.

Usually, you do not need to prefix a domain name with !rdap-dns and just !rdap should work fine.

Usage:
!rdap-dns <domain-name>

Examples:
!rdap-dns hello.com
!rdap-dns 中国人寿保险.net
!rdap-dns ietf.org
!rdap-dns atlast3d.com
!rdap-dns google.com
!rdap cloudflare.net
!rdap google.is
!rdap bing.com
!rdap yahoo.net
