Website cannot be accessed by IP address
It’s not possible to check website availability by IP address on a virtual hosting. This is due to technical specifics of virtual hostings: there are multiple websites on a single server IP address.
At the website’s IP address, there is a page by default: “The website is safely parked and waiting to be opened”.
If you want to have your website open on a dedicated IP address, you can purchase a service of additional IP address.
