You can create a custom hostname by first registering a domain name from an ICANN accredited domain registrar, then set the domain name to your own server. You must then create an A record for your custom hostname in the Domain Name System (DNS) for your domain to be resolved correctly.
Once you’ve taken these steps, you can then configure your web server software with your custom hostname. By updating your server software, web browser and/or email clients, etc., you’ll be able to use your custom hostname as the name of your website or online business.
You can also use your custom hostname to create unique email addresses with your domain. For example, you can have a generic email address such as “[email protected]
” or you can create a custom address using your hostname, such as “[email protected]
It is also important to keep your custom hostname updated to make sure it resolves correctly. You can do this by checking your DNS server and ensuring that the A record you’ve created is up to date.
