I understand you'd like to monitor for changes in WHOIS information, specifically the following fields: Registrar Registrar Registration Expiration Date Registry / Admin / Tech Registrant ID Name Server
We'd like to gather more information regarding your feature request. Would you also be interested in the following? 1. Automatically monitoring important records from the authoritative name servers such as "www" and MX records when monitoring a domain 2. Checking if public DNS servers resolve the same IP addresses as the authoritative name servers, to detect propagation delays etc.
