用nslookup解析的时候为什么会多出一个 huawei.com1的后缀呢？

原来nslookup解析域名的时候会自动把domain附加在输入的名字后面

在nslookup中用set all检查参数

> set all
Default Server:  68.128.128.61.cq.cq.cta.net.cn
Address:  61.128.128.68

Set options:
  nodebug
  defname
  search
  recurse
  nod2
  novc
  noignoretc
  port=53
  type=A
  class=IN
  timeout=2
  retry=1
  root=A.ROOT-SERVERS.NET.
  domain=huawei.com1
  MSxfr
  IXFRversion=1
  srchlist=huawei.com1

原来附加了一个huawei.com1

修改一下set nosearch

然后再解析就对了
