A domain host is an internet service that manages your domain name, for example, domain_name.com.
Domain hosts such as Web Hosting Magic uses Domain Name System (DNS) records to connect your domain name with email, websites, and other web services.
First of all, check your billing records.
Your domain host is typically who you bought your domain name from.
If you don’t remember who your domain host is, search your email archives for billing records about registration or transfer of your domain name.
Your domain host will be listed on your invoice.
If you can’t find your billing records, you can search for your domain host online.
The Internet Corporation for Assigned Names and Numbers (ICANN) is a non-profit organization that collects domain information.
Use the ICANN Lookup tool to find your domain host.
Go to lookup.icann.org.
In the search field, enter your domain name and click Lookup.
In the results page, scroll down to Registrar Information.
The registrar is usually your domain host.
Another method is to pull up your Terminal and issue the command: whois domain_name.com.
If you use a third-party DNS host for your domain, the registrar listed in the ICANN Lookup is not where your domain records are managed.
Sign in to your third-party DNS host to access your domain records.
