Historical name servers records
I recently bought a domain and used various free appraisal services to evaluate the domain name. To my surprise one of these services indicated the name have MOZ rank! So i thought this name must has been used/bought before. But how to verify that? A quick google search and i found this https://whoisrequest.com/history/ And i was right this domain name and actually another couple i own where created and dropped way back. Lucky me
