You need a domain name (URL) for your website. Go get one! We use Hostnet.nl, but any domain registration service provider will work. We like to keep the domains separate from the hosting, but it’s no problem to get them from the same company.
Think before you start if you want to register the domain under your own personal name or under a company name. In order to change this later, you will need to create a new account and transfer the domain name, which is a waste of time.
Think about taking the .com, .org, .net and other suffixes if you have a really unique name.
