Subdomain Description


A subdomain is a domain of a higher level in the DNS hierarchy. For example, cloud.dnspod.com and www.dnspod.com are two subdomains of dnspod.com, and dnspod.com is a subdomain of the top-level domain .com.

Subdomain levels description

When you add DNS resolution, you can use a subdomain to add records. The host can contain a–z, A–Z, 0–9, and dashes (-) to indicate the domain levels of the current plan. The total length of the host cannot exceed 100 characters, and each level cannot exceed 50 characters. The domain levels represent the number of domain levels that can be entered in the host, and the levels are separated by dots (.).
For example, www.dnspod.com is 1 level, m.www.dnspod.com is 2 levels, and so on.
The following uses the "Free plan" as an example to set a record where the subdomain levels is 2:
