It is worth noting that, in the administrative tools, open the Services tool and find the DNS client entry, which does not cache DNS

Concerning the string, there is nothing more than such algorithms and data structures: the trie diagram of the suffix array of the extend-KMP suffix tree in the KMP algorithm of the automatic machine and its application. Of course, these are relatively advanced data structures and algorithms. The most common and familiar data here is KMP. Even so, some people still do not understand KMP, let alone others. O
How to start a stand-alone server running Windows Server 2003 from a stand-alone server running Windows Server 2003 to become a network's DNS server. The first step is to assign a static Internet protocol (IP) address to the server. DNS servers should not use dynamically assigned IP addresses because dynamic changes to addresses can cause clients to lose contact with the

In fact, the functions implemented by DNS are very simple and effective, so that users do not need to remember the IP addresses that frequently access the server, you can directly access the IP addresses of numeric strings in a format similar to that in pinyin. Suppose we use 61.120.155.14 (for example) to use these numbers to access the Web server.

What is DNS.
Hosts on the internet, like humans, can be identified in a variety of ways. A host's identification method is to use its host name (hostname), such as CNN.com, www.baidu.com, etc., but the host name provides little information about the location of the host in the Internet. (a host named www.eurecom.fr ends with a country code. FR, tell
