RDAP is the replacement for the WHOIS domain information lookup protocol. Unfortunately, not every registrar supports RDAP (report).
This is a simple proxy server that uses the existing WHOIS server but returns the information as RDAP.
- IANA root domain database - info for each domain, including (if available), the whois server(s). This isn't really machine-readable. Try rfc1036/whois or whois/ianawhois.
- IANA RDAP for domains bootstrap file (JSON) - the official list of RDAP servers for domain lookups
- IANA list of RDAP servers for registrars - useful for finding a fallback RDAP server, especially if you buy all your domains from a single registrar.
- Resolve.rs report of unofficial/missing RDAP servers
To run locally for development:
./run.shGNU Affero General Public License v3.0
- echo
- rfc1036/whois - list of whois servers
- resolve.rs - list of rdap servers
-
list of allowed TLDs to proxy (redirect always works)
-
/index.html: note about allowed domains
-
/index.html display recent TLDs queried w/success ratio
-
cache raw whois results (and nocache parameter)
-
banner and social media metadata

undiabler/golang-whois: 6 years old, doesn't parse expiration, can't specify server (but has big list built-in)
-
likexian/whois: able to specify server and timeout
-
domainr/whois: includes parsers for HTTP-based whois servers
