Windows Professional platform resolve their host names to IP addresses, which is the same as those on other Windows operating platforms. DNS resolution requires support for Web browsers, as well as support for mail services and other applications that depend on host names rather than IP addresses. Windows DNS resolution stores the DNS query results, including affirmative queries, and of course queries that do not query resolution failures ). Each DNS record has a TTL value. This value determine

1. Ping Command Ping is used to determine whether the local host is connected to another host on the network. According to the default settings, the ping command running on Windows sends four ICMP echo request messages, each containing 32 bytes of data. If the network is connected, we should be able to receive four ICMP echo reply messages. The following describes how to use common parameters: (1) Ping-T host address: Send the echo request message to the host address consecutively, knowing t

host names rather than IP addresses. DNS resolution stores DNS query results, including affirmative queries, and of course includes negative queries (parsing failed queries). Each DNS record has a time to live (TTL) value that determines when the record is refreshed and then replaced by other queries. Before the TTL arrives, parsing returns the results of the query in the cache without starting a new query. When you want to troubleshoot connection and DNS issues, it is necessary to empty the

is a DNS resource record in the cache, the parser uses the records in the cache without querying the server. This behavior can increase query speed and reduce network traffic for DNS queries. You can use the Ipconfig tool to view and refresh the DNS resolver cache. To view the DNS resolver cache, type Ipconfig/displaydns at the command prompt.

Because DNS is a C/S structure and everyone is familiar with the concept of DNS server, it is easy to misunderstand that "DNS Client Service" is the DNS Client. If the "DNS Client Service" Client is disabled, the domain name cannot be resolved. The cause of misunderstanding lies in Microsoft's misleading situation. In Windows Service Management, Microsoft claims that "DNS Client Service" is "the name of the computer's DNS system for resolving and caching the domain name. If the service is stopp

time the DNS cache will return to your previous IP address, rather than the current public network IP address S. The following is a specific process: Use the command "Ipconfig/displaydns" to see all the records in the native DNS cache. A record of the ping-is-no-good.gicp.net is found in the following illustration: When a computer pings a domain name, it goes to the local DNS cache, and the

browser, and Ldns will be the domain name corresponding IP cache, so that the next time to return the same resolution faster.? After receiving the IP address of the Web site, the client requests the Web server corresponding to the IP addresses, and the IP of the site is locally DNS-cached, the Web server receives the request and responds to processing, and returns the contents of the client request to the client browser2.2.7 DNS Parsing principle3.

Any error resolution record is automatically saved in the System Event Viewer in 15 minutes, and we will be able to view the DNS server for incorrect parsing records in the future when we enter the viewer. To see all of the local DNS resolution records at a glance, do not need to open the DNS console window in a step-by-step way to find the appropriate viewing interf

Domain Name Server authorized by baidu.com to the local DNS server. The local DNS server continues to initiate a query to baidu.com to obtain the IP address of www.baidu.com. After obtaining the IP address corresponding to www.baidu.com, the local DNS server transmits the IP address to the user in the form of a dns response packet and creates a DNS Cache table locally. Command for viewing and clearing the DNS Cache table in Windows: ipconfig/

Generally this situation, is due to the computer system DNS parsing problems, and then introduce the solution to this problem.The first step, clear the DNS resolution cacheOur system caches some of our usual DNS addresses, which are designed primarily to speed up our access to the network. But sometimes these cached DNS addresses are not working properly for some reason, causing our web pages to fail to open. All we have to do is clear the DNS addresses of these system caches.1. first press and

Sometimes you may encounter such a situation, the computer suddenly can not be on the net, or there are some sites could not open the situation, but other sites may open. A lot of this is due to DNS cache latency.

Summary of methods to make the hosts configuration file immediately effective Do Web development and testing, it is inevitable to modify the hosts frequently to specify a domain name to access a particular IP; In Windows, every time you modify the C:\windows\system32\drivers\etc\hosts, you need to restart the browser to take effect. Today I do this problem on the line to learn, the following three methods, of course, not necessarily for everyone is effective, you can try it. method One: Comma
