DNS is divided into client and server. The client plays the role of question, that is, to ask the server a domain name, and the server must answer the real IP address of this domain name. The local DNS first queries its own database. If your database does not exist, you will ask the DNS set up on the DNS. After you get

I. Domain Name and domain name resolution NetworkIn order to distinguish each host, you must assign a unique address to each host. This address is called "IP AddressAddress ". However, these numbers are hard to remember, so they are replaced by domain names. HoweverThe host can be accessed only when the domain name is converted to the corresponding IP address.The DNS service, also known as the domain name resolution service, provides mutual conversio

In the actual application process may encounter the problem of DNS parsing errors, that is, when we access a domain name can not be completed to resolve the work of the IP address, and the direct input of the Web site IP can be normal access, this is because of DNS resolution failure caused.

(1) restrict name server recursive query Disabling recursive queries can enable the name server to enter the passive mode. When it sends a query request to an external DNS, it will only answer the query request for its authorized domain, instead of caching any external data, therefore, it is impossible to suffer from cache poisoning attacks, but such actions also have negative effects, reducing the speed and efficiency of

DNS domain name resolution The purpose of the domain name resolution is to convert the website name that users use to the TCP/IP protocol, and hostname is just convenient for people to remember, after all, IP is a pure digital address to the user is very unfriendly. However, when using TCP/IP communication, the computer is implemented through the IP address +port port number, so when we type a host name in the browser, we eventually need to convert

Full-automatic: DNS dynamic Update in Windows 2000 Domain Name System (DNS) provides a way for domain names (such as ftp.microsoft.com) to resolve with the corresponding IP address or multiple addresses. DNS is a scalable, distributed resource logging database that provides name resolution for the largest network, such as the Internet. In

The premise for the commercial use of IPv6 is that IPv4 addresses are exhausted. For this reason, we urgently need the IPv6 protocol to improve this situation. So how does IPv6 distribute DNS servers? Next we will analyze the principles in depth. Hope to help you. What is the architecture of the IPv6 Domain Name System? The DNS in the IPv6 network is consistent with the IPv4

We may encounter DNS resolution errors during the online process, that is, when we access a domain name, we cannot resolve it to an IP address, however, you can directly enter the website IP address for normal access, which is caused by a DNS resolution failure. This phenomenon has a high probability of occurrence, so this article will teach you some basic methods to eliminate

In actual application, DNS resolution errors may occur, that is, when we access a domain name, it cannot be resolved to an IP address, however, you can directly enter the website IP address for normal access, which is caused by a DNS resolution failure..Common Causes of DNS failure include:The domain name itself has expired or has been stopped;The
