Self-made local DNS servers accelerate bandwidth When we install a broadband network, the ISP (Internet Service Provider) usually provides several DNS server addresses and then sets them in the Internet TCP/IP protocol settings window. At present, I believe everyone has encountered network problems caused by DNS. For example, the speed of webpage opening is too

The probability of this phenomenon is relatively large, so this article will be from the beginning of zero to teach readers some basic troubleshooting DNS troubleshooting methods. first, what is a DNS resolution failure? Generally speaking, as we visit the www.jb51.net,www.kanshule.com these addresses are called domain names, and it is well known that any host in the network is the IP address to identif

Each IP address can have a host name that consists of one or more strings separated by a decimal point. With the hostname, do not memorize each IP device IP address, just remember the relative intuitive meaningful host name on the line. This is the function that the DNS protocol will perform.Today we will discuss DNS servers, especially Linux DNS servers, and how

Windows2000 as a brand new operating system, its biggest feature is the introduction of Active Directory, and the Active Directory is one of the biggest feature of the DNS and Active Directory tightly together. So how do they work together and what do they do? This often becomes a puzzle for beginners. In this paper, we will make a brief discussion on the relationship between the two, hoping to help you. A The difference between the two The combinatio

When we install a broadband network, the ISP (Internet Service Provider) usually provides several DNS server addresses and then sets them in the Internet TCP/IP protocol settings window. At present, I believe everyone has encountered network problems caused by DNS. For example, the speed of webpage opening is too slow, some websites cannot be accessed, or the pages in IE browser cannot be displayed. To solv

DNS concurrently consumes UDP and TCP port 53 is generally accepted, this single application protocol uses two kinds of transport protocol in the case of the TCP/IP stack is also a kind of alternative. The following describes the conditions under which DNS is used in each of the two protocols.Introduction to TCP and UDPTCP is a connection-oriented protocol that provides reliable data transfer, and the gener

Small to big: Exploring the Security Application of DNS in Enterprise Domain Environments DNS applications within an enterprise are almost ubiquitous. As long as we don't want to remember the pure IP address information You need to use DNS to provide us with simple name memory, such as ing an IP Address: 192.168.10.1 For one, this becomes a good memory, and for

Article Title: rapid integration of DHCP and DNS services in Linux networks. 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 daily network maintenance, especially on campus network maintenance, Managing IP addresses of hundreds of machines is a pain point for system administrators. Reality 1: the Internet connec

Build a master-slave DNS server and explain important transfer and recursive attributes 1. The main function of allow-recursion is to allow recursive queries on hosts to prevent DNS servers from hanging up or wasting network resources. For example, only recursive DNS queries of hosts in the 1.1.1.0/24 network segment are allowed, and recursive queries of other ho

Maintenance is important when you are setting up to use the Windows Server service. Let's talk about how to maintain and troubleshoot DNS failures. First, the use of dnscmd to facilitate the maintenance of DNS system Similar to UNIX or script commands, the Windows 2000 Resource Kit provides a command-line program called DNSCmd, which is used to manage DNS server

The domain controller is the core of corporate network management, and its failure often causes the logon failure of the whole network user's computer. However, when you set up a domain controller, you often ignore the DNS settings, causing the DNS in the domain to cause frequent failures. Do you know the importance of DNS? What would happen if
