You can check your hostname under Webmin > Networking > Network Configuration > Hostname and DNS Client. Unfortunately, some hosting companies overwrite this information every time a VPS is rebooted - you may need to contact them to get it changed. Choose a fully-qualified subdomain that you own, such as "webserver.mydomain.com" or "mail.mydomain.com". Do NOT accept a generic name provided by the hosting company if you will be sending email from the server because spam filters will block it and you can't easily generate SSL certificates for it.

After our best VPS hosting review, we found that HostGator is the best choice on the market. They offer different pricing plans that perfectly fit your needs regardless of the size of your business. Whether you want to build a resource-heavy site or a site that anticipates rapid growth in the near future, you’ll find the right hosting plan that suits your needs.
Once you register your website's domain name, it's time to start picking the specs for your server. Web hosts typically offer multiple VPS plans that have varying amounts of email capability, RAM, storage, CPU power, domain hosting, and monthly data transfers. The plans typically include website builders that let you quickly create a face for your site without much—or even any—coding required. A solid web host should offer at least 4GB of RAM, 100GB of storage, and an ample volume of monthly data transfers. If you expect a significant amount of website growth, then you should look for a web host that has as many unlimited offerings as possible. For example, Hostwinds—the PCMag Editors' Choice for VPS hosting—offers unlimited email, domains, and monthly data transfers. Note, however, that as with all unlimited service offerings, you really need to read the fine print to make sure that what you mean by unlimited and what the hosting service means by it.
