MassRDAP

Information

This script will take an input list of domains and retrieve WHOIS information for them using the Registration Data Access Protocol (RDAP). Depending on the TLD the domain is under will determine which RDAP server the request is made on. We are using the Bootstrap Service Registry for Domain Name Space from IANA.

This is a work in progress still (stay tuned)

Rate Limiting

From my experience, it seems every RDAP server has their employed rate limits. While I am still benchmarking and testing these limits, proxy support has been added to circumvent this issue.

Usage

Argument Description Default Value
-i, --input_file File containing list of domains (one per line).
-p, --proxy Proxy in user:pass@host:port format. If not supplied, none is used.
-c, --concurrency Number of concurrent requests to make. 25
-o, --output Output file to write successful RDAP data to. output.json
-f, --failed Output file to write failed domains to. (optional) failed.txt

WHOIS & RDAP Statistics

By comparing the root TLDS and the RDAP Bootstrap data from IANA, along with querying IANA's WHOIS server to find other TLD's WHOIS servers, we can formulate coverage statistics on WHOIS/RDAP availability across all available TLDS:

RDAP
Status Results
RDAP 1,174 (81%)
No RDAP 275 (19%)
WHOIS
Status Results
WHOIS 1,253 (86%)
No WHOIS 196 (14%)

Roadmap

  • Explore other RDAP servers from RIRs, registrars, IANA (see here)
  • Mass domain availability lookups
  • Find available 1 or 2 letter domains.
