Other information is unavailable. If you need to troubleshoot DNS (Domain Name resolution system) faults, you must be familiar with another powerful command-

Today, under the Linux server encountered a strange problem: The network domain name ping results and nslookup results inconsistent, the resolution process is recorded as follows.
