A domain name is a unique name on the internet. My domain name is nexus-studio.eu. Domain names are usually used for websites. But you can also request a domain name for a personal email address. A domain name has a long number as an address: the IP address. Because such a number is difficult to remember, the domain names were invented. The domain name system (DNS) translates the IP address into a domain name.
To visit a website, type an address or URL in a web browser (chrome / edge / firefox / safari). This is usually shown at the top of the bar. This address includes the domain name.
A domain name is required to host a website or use mail services. You can register this with Nexus Studio. I then link this to the web hosting package. If you have registered a domain name somewhere else, I can move it or have the DNS adjusted so that you can still use Nexus Studio Webhosting or, for example, Microsoft 365 business.
