A domain registrar is a company accredited to register internet domain names. When you buy a domain like example.com, you register it through a registrar like GoDaddy, Namecheap, or Cloudflare.
We perform a WHOIS lookup on the domain, which returns registration details including the registrar name, registration date, expiry date, and nameservers.
Nameservers tell the internet where to find a domain's DNS records. They're often set to the hosting provider (e.g., ns1.cloudflare.com) and can differ from the registrar.
Most .com, .net, and .org domains have publicly accessible WHOIS data. Some domains use WHOIS privacy services (like Domains by Proxy) that replace owner details with the privacy service's info.
