The Internet is built from unique elements that have their own digital designation in the form of an IP address and its symbolic designation - a domain name. Information on the structure of the Network is generated and used decentralized in special databases.
Domain names are painted by zone. Basically, this distribution by country: .ru, .by, .ua, .kz, .eu, ... There are international designations: .com, .gov, .org, .info, .edu, ... There are also geographical options: .eu, .asia, .berlin, .london - and names provided by special servers. This is the first level.
