DNS server is not unfamiliar to everyone, the site to do the domain name resolution to the corresponding IP address so as to achieve the purpose of resolution. Webmaster daily to do the station outside the optimization, select the site server and whether the DNS will become a hidden in the site behind the killer? The speed of the Web site not only depends on the program, running the server, as well as the
Introduction:DNS (domain Name System, domainname), Internet as domain name and IP addressa distributed, mutually mappedDatabase, enabling users to access the Internet more easily, instead of remembering the number of IP strings that can be read directly by the machine. Through the hostname, the process of eventually getting the IP address for that hostname is called Domain name resolution (or hostname resolution). The DNS protocol runs on TCP and UDPp
When sending an email, Postfix uses the system's resolver (that is, the DNS client, which can query domain information from the DNS server) to obtain DNS information.

Overview of DNS system parsing process
DNS (domain name servive) is the most basic and important service in internet/intranet, providing automatic conversion of domain name to IP address in network access. We know that there are thousands of hosts on the Ineternet, and are constantly increasing, it is impossible for one or several DNS servers to implement such a
Objective:What is DNS polling?A domain name for multiple IP A records resolution, the DNS server will resolve the request in the order of a records, one by one assigned to a different IP, so that the simple load balancing the benefits of DNS polling: 0 Cost: Just binding a few a records on the DNS server, domain regist
Servers are not only the hub of enterprise network equipment, but also the main body of enterprise software and database applications. In practice, servers often encounter one or another failures, software or hardware. Many faults are irregular, and we can only solve them through experience. I am responsible for the maintenance of the company's servers. I encountered a strange DNS Network Fault in my actual work and the server could not log on to the
Article Title: explores the running status of the Linux System DNS server. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
In Linux, it also provides a popular BIND server, which is the most commonly used server software for building DNS servers. There are many articles
The principle and process of DNS parsing.When a user visits a webpage on our site, he needs to go through the following steps:1) Find the storage server for this webpage;2) The server will access the user's request information;3) The server locates the user request webpage through the file path (URL);4) The user downloads the content of the webpage to their computer.The DNS resolution we are talking about i

I. Basic DNS knowledgeAs we all know, in network communication, data links Use MAC addresses. The network layer uses IP addresses, and the transport layer uses port numbers, each of which has its own identification method. IP addresses are the most closely related to users. Each incoming computer (whether Internet or intranet) must have its own IP address to ensure correct inform
If the DNS settings are not good some sites can not open, we may fill out their preferred DNS, the following cloud habitat small set to introduce you to the domestic common DNS address.

First, what is DNSDNS (domain Name System), a distributed database of domain names and IP addresses that are mapped to each other on the Internet, makes it easier for users to access the Internet without remembering the number of IP strings that can be read directly by the machine. The process of obtaining the IP address of the host name through the hostname is called Domain name resolution (or hostname resolution). Two ways of DNS query1) Recursive p

The role of DNS resolution is to resolve the domain name to the corresponding IP address, because the router needs to know the IP address on the WAN to know who sent the message. DNS
First, the experimental simulation environment:Zhuyu company has a DNS server, because the DNS server is older, ready to migrate to a new DNS server (DNS backup can do so).Legacy DNS Server:Host name: Test-zhuad IP Address: 192.168.10.30New
We can use commands at the command prompt to clear the information in the DNS client cache. After the client executes the "Ipconfig/flushdns" command, the "ping" command appears after the letter is prompted to resolve the problem.
It is worth noting that, in the administrative tools, open the Services tool and find the DNS client entry, which does not cache DNS
Because it's all Windows platforms, it's nothing. Well, take a look at our environment:
Original DNS server:
