Subdomains allow you to maximize the utility of your domain name, allowing you to create multiple sites all using the same domain name. Here is how to set up a subdomain in your MacHighway web hosting service.


What is a subdomain

A subdomain is a prefix to your main domain name (Ex. Each subdomain is considered to be its own website, even though they share a domain name.

If you have a store or blog alongside of your website, you can create a subdomain for each (, This is also helpful if you are using apps with your domain. You can create as many subdomains as your current plan allows. Each subdomain will have its own document root where you can upload a website or install a web app.

Subdomains can also be set up to redirect to a different service. If you have a blog hosted on a separate service, you can redirect your subdomain to this site. This allows you to use any service available, but still use your domain name to promote it.

Using subdomains will allow you to expand your online presence and increase your visibility, without the need to register more domain names and confuse your end users.
