Whether on the LAN or the Internet, people also face another confusion: the computer on the network can only identify such as "18.104.22.168" such as digital address, then why when we open the browser, in the address bar input such as "www.popunet.com" After the domain name, you can see the page we need?
In fact, the above two problems, are just an IP address and domain name each other "translation" process. The former has to establish a domain name Mapping record that points to the corresponding IP address; for the latter, this record has been established and is in effect. The creation of this "translation" record requires that the same computer known as the "DNS server" be used.
DNS servers are used in TCP/IP networks (such as a general LAN or Internet) to locate computers and services by replacing difficult IP addresses (such as "22.214.171.124") with user-friendly names, such as "www.ddvip.com". Therefore, as long as you need to use such as "www.ddvip.com" domain name, you have to first ensure that the name in the DNS server for the corresponding and IP address mapping work.
This article takes the Windows 2000 Advanced Server Edition (hereinafter referred to as Win2000) with its own DNS service as an example, step-by-step teaching you how to complete this "translation system" in the LAN to build work.
First, add DNS service
By default, the DNS service is not added after you install the Win2000. Open the Control Panel → add/Remove Programs → add/Remove Windows components, and then in the Components list, double-click Network Services, and then check the "DNS Server" item below, and then press OK.
The goal of this article
1, assuming that this machine has a "192.168.0.51" IP address, now want to let it and "ddvip.com", "www.ddvip.com" and "ftp.ddvip.com" corresponding to three domain names.
