The main domain on a web hosting account is the domain that was entered when the account was ordered/created. It is also what is shown on invoices from us regarding the account. There are no specific advantages in using an important domain as main domain on a web hosting account. It is also not possible to change it without our involvement.
If you wish to change the main domain on a web hosting account, you need to contact us. Keep in mind that we only change the main domain if the current one is to be added to another hosting account or in similar situations (the main domain neither have to work nor point towards our servers). When changing the main domain, we always use a subdomain on the domain hemsida.eu. This to avoid a situation in the future where a new change is required.
We always recommend that you add your most important domains as addon domains on the account, since those are more flexible than the main domain. E.g., you can modify the document root for an addon domain whenever you like, a feature that is not available for main domains (they always use public_html
).
