After the first three sections of the matting, presumably we should have a basic understanding of DNS and related concepts, this section began to discuss the DNS server installation and configuration, but also have the client settings, the content is very basic.
Today our test environment is made up of a single server

In network optimization and network security protection, we may need to use to modify the DNS server address, the next small series to share with you how to modify the DNS address, here to the current WIN8 system as an example, teach you how to modify the computer DNS address, the need for friends may wish to refer to.
Two days of indulgence, to get physically and mentally exhausted. I was almost late in the morning, but fortunately I stepped on it. Oh!In Friday, because the notification Sunday power outage, so the server, such as shutdown equipment, etc. are shut down. So the first thing I do is give them electricity. The buttocks just sat down, the colleague said the computer can not go in, in the Welcome interface has been spinning, 10 minutes. Another colleague
Overview: What is DNS spoofing?
DNS Spoofing is the art of changing the original IP address of DNS. For better understanding, let's look at an example. If you want to use a browser to search for some information on Google, you can enter the information in the address bar without a doubt.
Www.google.com
And press Enter
First, DNS primary configuration fileA list file for a/etc/hosts-host-contains a list of known hosts (on the local network) if the system's IP is not dynamically generated, it can be used for simple host name resolution (dot notation/etc/host.conf-Conversion Program control file-tells the network domain name server How to find the host (usually/etc/hosts, then the domain name

specified Query type is used to search for address resource records using this name. The system regards DNS query as a two-part question raised by the client to the server.

example, the specified name can be a fully qualified domain name for the computer, such as im.qq.com, and the specified query type is used to search for an address resource record through that name.DNS queries are parsed in a variety of different ways. Clients can sometimes answer queries in place by using cached information obtained from a previous query. The DNS serv
People may have such a puzzle: computers on the network can only identify such as "123.123.123.123" such as digital address, so why when we open the browser, in the Address bar to enter the domain name dns.qy.com.cn, we can see the page we need?
