Chapter 1: DNS
1.1 Introduction
The most basic service in a TCP/IP network is domain name
DNS is the abbreviation for the domain Name System. Everyone in the Internet input URL, is through the domain name resolution system to find the corresponding IP address to access the site. But the recent Microsoft Windows 2000 and Windows 2003 DNS services have a very high security vulnerabilities, if hackers successfully exploited, then our internet operation will encounter great trouble.

When it comes to dns, you will always think of bind. Although bind is powerful, it is too complicated and it is a headache for configuration. Killing a chicken with a knife is not a zombie, but a fear that the knife will hurt your feet. Dnsmasq is much easier to use than the dns ancestor bind.

At present, domestic telecom operators use DNS hijacking and DNS pollution to interfere with normal internet access and prevent u

Set up a dns server on centos to resolve any domain name
Function:1. Recently, the company launched a new web server, such as 111.111.111.111.Colleagues are required to test whether the server is normal. In a LAN segment, it is difficult for everyone to modify the hosts. This method can be used.For example, yumaozdy.co
DNS is a naming system that converts a human-readable domain name into a computer that can recognize IP addresses. When a domain name query request that does not exist in the parser cache appears, the conversion process is from the root server to the top-level domain name, for example. com domain name) in the entire DNS hierarchy. Next, the top-level domain name

In a network set up with the TCP/IP protocol family, each node has a unique IP address that is used as their only token. However, it would be unthinkable if the user were to be remembered for such an IP address without a memory rule. People need a string of memory rules to be the name of a unique tag node.
However, although the symbol name is very convenient for people, it is not so convenient to implement on the computer. In order to solve this demand, a Domain Name Service system
Here we use the Linux Bind server software for the DNS service for this test.
