The domain name system (DNS for its acronym in English) is a naming service that converts the known user domain (for example, "www.homepage.com") into the respective IP address. If you send the domain name as a query in the address bar, the domain is translated from DNS and then the request is transferred to the appropriate server.
A domain consists of several parts:
- DNS root
- Top Level Domain (TDL)
- Second level domain (SDL)
- One or more subdomains
- Hostname (hostname)
Top level domain (TLD)
The top-level domain, which represents the geographic mappings (country code top-level domain - ccTLD) is placed after the root level. Examples of this are:
- «it is" for Spain
- «from»For Germany
- «fr»For France
- «Item»For Italy.
The TLD can also represent institutions.
