Much like how DNS maps a domain title to an IP handle, ENS was developed to map blockchain addresses to human readable labels.
Normally called the “phonebook for the world wide web,” a more modern analogy is always that DNS manages domain names in A lot the exact same way as smartphones take care of contacts. Smartphones get rid of the necessity for end users to recall individual cellphone numbers by storing them in simply searchable Make contact with lists.
The DNS architecture consists of two sorts of DNS servers, recursive servers and authoritative servers. Recursive DNS servers are those executing the “inquiring,” trying to find the data that connects a person to an internet site.
