What is a Subdomain?
A subdomain is a way to have a secondary server or service running on a domain. It can be another website that contains it’s own unique content without an entirely new domain needed to be created. Alternatively, it can be another service entirely, like mail.example.com or blog.example.com.
How Do I Create a Subdomain In Hostwinds Cloud DNS?
You can setup a subdomain in Cloud DNS by heading to Network > Domains from Cloud Control.
Step 1: Click Actions > Records on the domain you want to add a subdomain to.
Step 2: Decide if you want to use a CNAME or an A record
Step 2a: If the subdomain is hosted on the same IP address as the domain, a CNAME record can be used pointing it to the main domain name.
Step 2b: If the subdomain is hosted on a different IP, an A record will be used to point it to the other IP address.
Step 3: With the record type selected, enter the subdomain name by itself in the second field.
Step 4a: If using a CNAME, enter the main domain in the 3rd field
Step 4b: If using an A record, enter the new IP address.
Step 5: Leaving the TTL at the default 3600 seconds (1 hour), click Add.
The DNS for the subdomain has been created, you can now add a virtual host on your server to listen.
