The protocol used to resolve what is DNS?

DNS is an Internet and TCP/IP service used to map network address numbers. DNS, as a distributed database that can map domain names and IP addresses to each other, allows people to access the Internet more conveniently without having to remember IP strings that can be directly read by machines.

For example, 191.31.140.115 is mapped to an easy-to-remember name, such as tbones. acme. com. Internet.

TCP/IP utilities such as telnet File Transfer Protocol (FTP) and Simple Mail Transfer Protocol (SMTP) also access DNS to determine the name you specify and resolve it into a network address.

When a name is selected, DNS translates the name into a numeric address and inserts it into the transmitted information.

An important feature of DNS is that its address information exists in multiple places in a hierarchical structure, rather than in one central site. Each location has a domain name server to maintain local node information.

Domain name service, as a distributed database that can map domain names and IP addresses to each other, allows people to access the Internet more conveniently without having to remember IP strings that can be directly read by machines.
