Root domain – the domain of the highest level in any domain name system. The root domain of the Internet (sometimes called the zero-level domain) is serviced by the root servers of the domain name system, which are located in different countries around the world.

In the Internet DNS system, the root domain is denoted by an empty name (that is, containing no characters). When you record a domain name, each domain is separated by a period; at the end of the name there may be a dot to separate the empty name corresponding to the root domain. If this dot is present (for example “www.example.com.”), then the domain name is considered complete (absolute). If there is no dot at the end of the name (“www.example” or “www.example.com”), the name is considered relative.

Each Internet application must process the end point correctly, but most applications allow you to enter a domain name without a dot at the end; processing of such names depends on the implementation. In the simplest case (if, for example, in the context of this application it is impossible to determine which address is assigned to the base domain) a final dot will be added to URL address, and it will be treated the same way as the absolute one. In some cases, in order to obtain a full domain name, local software (either an application or an operating system) can attach a domain to a default relative name, which is determined by the domain name of the computer or can be specified in the settings. Sometimes, several such domains can be set within the settings, sorted by turns, until the name existing in the DNS is found. This approach can lead to ambiguity, which, however, can be easily resolved by specifying a complete (with a dot at the end) domain name.

The numbering order of domain names is often mixed up, and top-level domains (TLD) are called ”zero-level” domains. In fact, a zero-level domain is “.” (dot) and the correct order of domain levels numbering is as follows:
1. .(dot) – zero-level domain
2. .com is the first-level domain, also called the top-level domain or a zone
3. kparser.com – second-level domain
4. app.kparser.com – third-level domain
