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.

The Domain Name System (DNS) is a distributed database system that resolves domain names to IP addresses. The DNS is critical for the functioning of the Internet, as it allows devices to communicate with each other by translating domain names into IP addresses. One of the DNS’s primary functions is to provide name resolution for Internet Protocol addresses.
A top-level domain (TLD) is a type of domain name in the Domain Name System (DNS), which is the system that provides name resolution for the Internet. The DNS is implemented as a distributed database across multiple servers. TLDs are assigned by the Internet Corporation for Assigned Names and Numbers (ICANN) and are used to label the addresses of websites and other Internet resources.
Domain Name System (DNS) is a hierarchical naming system for computers, services, and other devices on the Internet. DNS is a distributed database that stores the corresponding addresses of domain names and their aliases. DNS is divided into levels, each of which provides increased functionality.
DNS is the system that allows computers to find each other on the Internet. When you type a website into your browser, your computer queries a DNS server for the address of the website. A DNS server can hold a list of up to 216 DNS records for a given domain.
A DNS search domain is a domain name that is used by a DNS server to locate a specific host name or IP address.
Domain Name System (DNS) is a hierarchical distributed database that provides a way for devices on the Internet to communicate with each other by name. Each device on the network has a unique IP address, but most devices have names, such as “www.example. com.” DNS maps these names to their corresponding IP addresses.
A DNS search domain is a specific type of domain name that is used to perform a DNS lookup. A DNS search domain is different from a hostname, which is the name that is displayed to a user when they type in a website address. A DNS search domain is a specific type of domain name that is used to perform a DNS lookup. .
Domain Name System (DNS) sub domains are a type of domain name. A sub domain is a portion of a domain name, typically a subsection of the domain name that is specific to a certain organization, website, or service. A DNS sub domain is a domain name that is under the control of a separate DNS server from the main domain name.
