Your Capsul needs a hostname, also known as a domain name. There are many services which provide domain names, such as [Gandi](https://www.gandi.net) and many more. You need to register a domain name, and then set up DNS records to connect your domain name with the IPv4 address assigned to your Capsul when you created it.

Each domain registrar has a different user interface for managing DNS records. Set up three 'A' records. One for the domain itself, one for www.your-domain-name, and one for subdomains of the domain. It will look something like this:

 **Be sure to remove CNAME and ALIAS records.**  
 
 After you save your updated DNS records, you can verify they've been propagated with the [DNS Checker](https://dnschecker.org/) website. The green check marks indicate the name has been propagated.
