但我们可以使用set type命令修改去查询另一种资源记录类型，下面的例子将会可检查SOA记录。请注意，如果将查询类型设置成SOA。它将保持SOA不变，不会返回默认的A型查询。如果我们需要查询A记录，则还需要使用一次set type命令。<br>
<br>
$ nslookup<br>

Default Name Server: rs10.hrz.th-darmstadt.de<br>
<br>

同样，可以使用set type查询MX记录，或修改成专用查询类型ANY，ANY可以用来取得指定主机的所有可用资源记录。<br>
<br>

nslookup命令的另一个应用为named.ca文件是获取当前根服务器的列表。我们可以使用set type=NS来查询所有的根域名服务器：<br>
<br>
$ nslookup<br>

Default Name Server: rs10.hrz.th-darmstadt.de<br>
<br>
Address: 130.83.56.60<br>
