What hosting service allows a company to host its domain name on a third-party ISP server?

The correct choice is Virtual Domain. This service allows a company to host its domain name on a third-party Internet Service Provider (ISP) server while maintaining the appearance of having its own domain. In a virtual domain hosting environment, multiple domains can share the same server resources, which reduces costs and makes it easier for smaller businesses to establish an online presence.

Virtual domain hosting typically entails using a third-party server without the need for the company to manage the physical hardware or server maintenance themselves. This allows businesses to benefit from shared resources, while still having a unique domain name and a tailored website configuration.

In contrast, shared domain hosting references a broader category of shared hosting services, while dedicated hosting involves a single server dedicated solely to one company's needs, leading to higher costs. Cloud hosting utilizes a network of virtual servers to host data and applications, offering scalability and flexibility but not specifically describing the hosting of a single domain on a third-party server in the same way as virtual domain hosting does.
