If you register a domain today, it can be found in the respective register (Whois) within a few minutes. However, the new domain cannot be used immediately after registration, as new domains first have to find their distribution worldwide. For this purpose, a zone transfer is carried out several times a day. Only when this has been started for the first time does a domain gradually become available worldwide. In general, one can assume 24 hours until global accessibility is given.
With a Whois query, information on Internet domains and their owners can be retrieved. The information is stored in a distributed database system.
