There are two ways to query the domain name history, one is through the well-known whois history query, but many of them are charged. Ordinary whois query can only find the current registration status of domain names, and the other is through historical snapshot query, which is more direct and free. For example, lookforpast can let you directly see the historical snapshot pictures of websites that query the target domain name, which is actually enough for domain name valuation and analysis.
