Domain registrar WHOIS referral client, RDAP inspector & expiry watchlist

A domain registration WHOIS (RFC 3912 TCP port 43) and HTTPS RDAP (RFC 7480 / RFC 9083) lookup utility and expiration watchlist for Linux. A lightweight Linux alternative to Sysinternals Whois with graphical registrar referral chasing, structured RDAP parsing, DNSSEC and EPP status inspection, and multi-domain expiration tracking.

Key features:

  • Queries whois.iana.org over TCP port 43 and automatically follows referrals across TLD registries and accredited registrar WHOIS servers.
  • Queries HTTPS RDAP domain endpoints (rdap.org and registry RDAP servers) to parse Registrar name, IANA Registrar ID, Creation, Updated, and Expiration dates.
  • Calculates days remaining until domain expiration with color-coded renewal status badges and a persistent multi-domain expiry watchlist.
  • Inspects authoritative nameservers, DNSSEC delegation status (DS key tags and algorithms), EPP status flags, raw WHOIS transcripts, and exports CSV and JSON reports.

Disclaimer: This project is an independent open-source tool and is not affiliated with, sponsored by, or endorsed by Microsoft, Sysinternals, ICANN, or IANA.
