一、引言 域名服务器(DNS)对于Internet和Intranet都是不可缺少的。传统上,作DNS的都是Unix机器。随着NT的兴起和发展,NT4.0也能用作DNS。对于中小型单位,选择NT4.0作网络服务器同时又作DNS是较好的方案。本文在实践的基础上对DNS原理及用NT4.0实现多级域名服务进行详细阐述。 二、域名解析 域名解析的作用是将域名转换为IP地址,分解析器和服务器两种角色。解析器是请求域名解析服务的软件,域名服务器是运行名字服务软件的机器。
First, the introduction Domain Name Server (DNS) for the Internet and Intranet are indispensable. Traditionally, DNS is Unix machines. With the rise and development of NT, NT4.0 can also be used as a DNS. For small and medium-sized units, choose NT4.0 network server at the same time as DNS is a better solution. This article elaborates on the principle of DNS and multi-level domain name service using NT4.0 on the basis of practice. Second, the domain name resolution The role of domain name resolution is to convert domain names to IP addresses, sub-parser and server roles. The parser is the software that requests the domain name resolution service, and the domain name server is the machine that runs the name service software.
