Use nslookup in Centos to query domain name servers

The simplest use of nslookup is to query the IP address corresponding to the domain name, which is applicable to A record or CNAME record. If you need to know who the domain name resolution server is, you can also use nslookup, but you need to add parameters. This command is provided by Windows and linux, but the parameter expressions are somewhat different, for example:

// Usage: nslookup parameter domain name // window usage nslookup-qt = ns netingcn.com//linux usage nslookup-type = ns netingcn.com

NOTE: If no parameter is specified, the IP address corresponding to the domain name is queried. The domain name of the domain name resolution server is its own top-level domain name. Do not add www.
