Use an ICANN registration-data lookup and review the registrar field.
Step by Step
- Open an ICANN-compatible domain registration lookup.
- Enter the domain name without a page path.
- Find the Registrar field.
- Use the registrar's official website to manage the domain if you own it.
If That Doesn't Work
- Privacy services can hide registrant contact information, but the registrar is normally still identifiable.
- The registrar and website host may be different companies.
