nslookup 和 name server 的差别

To query like a resolver, you use nslookup's default settings. To query like a name server, use set norecurse and set nosearch. On the command line, that's nslookup -norecurse -nosearch.

简单的说，nslookup默认采用searchlist并在查询时设置递归位。经过set -norecurse 和 set -nosearch 后，nslookup的行为和name server的行为一致。
