What is a top-level domain name
What is a top-level domain name? In response to this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more small partners who want to solve this problem find a simpler and easier way.
Top-level domain origin:
An IP address is a method of addressing a host on the Internet, also known as a network protocol address. IP addresses are often expressed in dotted decimal notation as (a.b.c. d), which is difficult to remember. Thus, the domain name (domain name) is a character-type identifier. DNS was first invented by Paul Mockapetris in 1983; the original technical specification was published in RFC 882. Draft Nos. 1034 and 1035, issued in 1987, amended the DNS specification and repealed draft Nos. 882 and 883. Since then, changes to the draft Internet standard have largely not involved changes to the DNS specification section. DNS is a domain name resolution service.
