DNS recursive query and iterative query Summary There has always been confusion about the "recursion" and "iteration" approaches to DNS queries. Most people just tell you. "DNS clients request recursive queries to DNS servers," and "query requests between DNS servers are i

One of the most important components of any current TCP/IP network is the DNS server. A number of things a DNS server can accomplish, such as parsing an Internet URL into an IP address, resolving the host name on the local network, and providing the infrastructure on which the Windows Active Directory depends. Therefore, deploying a DNS server is not a very simpl

This article describes how to use domain Name Services (DNS) in Windows XP by configuring the TCP/IP protocol. DNS is an Internet service that converts a domain name to an IP address. On the Internet, when you use a domain name during network operations, the DNS service is responsible for converting the domain name to the corresponding IP address. For example, d

Because the company has colleagues in charge of Dalian, Shenyang Two cities, often in both directions back and forth, to each city, they have to manually change the corresponding network configuration, and to live in the field is the hotel, the hotel is automatically access to the Internet IP, but also the network settings canceled, really troublesome! So I thought of writing a batch process! To solve this problem! The main command to use is netsh.-The first method is to set up the network confi

DNS Overview: DNS is the domain Name System, which is a distributed database, organized into a domain hierarchy of the structure of the computer and Network service naming system. Its role is: to transform the domain name into a network can identify the IP address, the results of the query to save, and told the client. Second, DNS query process 1. Local resolut

We can not remember more than 10 IP addresses of the site, so when we visit the site, more is to enter the do

This step-by-step article describes how to configure Internet access for Domain Name System (DNS) in the Windows Server 2003 product. DNS is the core name resolution tool used on the Internet. Responsible for resolution between the host name and Internet address.　　How to start from a stand-alone server running Windows Server 2003　　A stand-alone server running Windows Server 2003 becomes the

Most network communication is based on TCP/IP, while TCP/IP is based on IP addresses. Therefore, when a computer communicates over the network, it can only identify IP addresses such as "202.96.134.133, but cannot recognize the domain name. We cannot remember websites with more than 10 IP addresses. Therefore, when we visit a website, we enter a domain name in the address bar of a browser to see the desired page, this is because a computer named "DNS

Article Title: DNS server security strategy under solaris10. 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. A DNS server is a server that provides domain name resolution services for hosts on the network. Although Solaris 10 comes with BIND 9.2.4, it is not a product of

When sending an email,PostfixUse the system's resolver (that isDNSClient, which can query the domain information function library from the DNS server) to obtain DNS information. When receiving A mail, the DNS of your domain must provide delivery information (MX or A record) for external queries so that other MTA can find your postfix server. Influence of

clear information about the location of the house. Services provided by DNS We already know that you can use the host name to identify a master sail or an IP address. People prefer to use host name identifiers that are easy to remember, while vrouters only wish to use IP addresses with fixed length and hierarchical structure. To mediate these two different preferences, we need a directory service that converts the host name to an IP address. This is

At present, many enterprises and institutions have set up units within the LAN, the internal network are equipped with related servers (such as Web, FTP and other servers). Internal network users want all servers to use domain names to access, network administrators can use the way to build a DNS server to achieve. Set up a DNS server on the internal network that allows users to enter the IP address of the

1, DNS is the domain name server, his task is to determine the domain name of the resolution, such as a record MX records and so on. 2, any domain name has at least one DNS, is generally 2. Why do you need more than 2? Because DNS can be used for recycling, the first parsing failure can be found in a second. So as long as there is a normal
