Domain Tools FAQ
What information does a WHOIS lookup reveal?
A WHOIS lookup reveals the registrar where the domain is registered, the creation and expiration dates, the assigned nameservers, and sometimes the contact information of the registrant (if not hidden by privacy protection).
Why should I check my DNS records?
Checking DNS records is crucial when migrating a website, setting up Google Workspace/Office 365 emails (MX records), or verifying ownership (TXT records). It confirms whether your recent DNS changes have propagated across the internet.
How accurate is the Domain Age Checker?
The Domain Age Checker calculates the exact time elapsed since the domain's original creation date as recorded in the official WHOIS database, making it highly accurate for determining the historical age of a domain name.
