196543 WhoIs Lookup & Compare Records

Hello, I have about 100 - 500 websites I am monitoring. I would like to actively check these domains for changes to their WhoIs records every hour or daily.. etc. Hopefully I can set these settings based on the number of domains I am checking. Basically, I would like an email sent to me if there is changes in the Whois info of a domain in my list. The email will contain: Original WHOIS information _______________________ New WHOIS information _______________________ Time Stamp Change Was Noticed _______________________ Registrar Name & Domains Status: OK, Pending Delete, and so on.. _______________________ This script will grow with time & eventually will monitor millions of domains. We can discuss this at a later time.
