Yes, you may use virtual hosts to connect up to 100 domains/subdomains to a web hosting package with Domainnameshop.
You can connect any domain, even domains that are not hosted with Domainnameshop. In those cases, you may be required to set up DNS records to validate the ownership of your domain, as well as records to connect your domain to our hosting servers.
Virtual hosts are created by the administrator of the web hosting package. You can find an explanation here.
