When it comes to DNS, the number of hierarchical domain levels we can have is limited only by our imagination. In theory, DNS can support an unlimited number of levels.

However, in practice, the number of domains we can support is typically limited by the number of available IP addresses.

The DNS hierarchy is made up of a number of levels. The Lowest level is the domain name. A domain name is a unique name assigned to a specific domain.

For example, the domain name “com” is the name of a domain that contains the website “www.com.”.

The next level up is the subdomain. A subdomain is a portion of a domain name. For example, the subdomain “www” is the portion of the domain name “com” that is associated with the website “www.

com.” A subdomain can contain any number of websites.

The next level up is the domain. A domain is a specific name assigned to a specific domain name. For example, the domain name “com” is the name of a domain that contains the website “www.” A domain can contain any number of subdomains.

The next level up is the top-level domain. A top-level domain is a domain name that is not a subdomain or a domain.

For example, the top-level domain name “com” is the name of a domain that contains the website “www.

A domain name is a unique name assigned to a specific domain.
