What is the service from domain name to IP address conversion?

The conversion from domain name to IP address is DNS (Domain Name Service) domain name service.

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. .

DNS:

DNS is an Internet and TCP/IP service used to map network address numbers. 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 hierarchy rather than in one central site. Each location has a domain name server to maintain local node information.

Domain:

Domain and DNS were introduced with the development of the Internet. Its structure is a hierarchical tree with many branching subtrees and is part of the Internet. In a hierarchical file system, a directory has many subdirectories, in the same way you can imagine this tree of DNS. The top level of the tree, sometimes called the root level, is branched into several major branches called domains. Here are some top-level Internet domains:

GOV=Government Department

TECH=Technology Technology

EDU=Educational Institution

ORG=Organization (non-profit or non-commercial)

COM=Commercial

MIL=Military

NET=Network service provider

TOP=Top, peak (industry benchmark)

There are also country domains, such as CA (Canada), UK (UK), JP (Japan), DE (Germany), AU (Australia), and in the US (United States) domain, there is a two-letter code name for each of the 50 states. These domains are named by companies or organizations that are limited to one country. International companies use the COM domain.
