ping -a不解析Windows 7客户端的一个主机的主机名
ping -a 192.168.99.3不解析vcl.nailit.lab的主机名，而是解析网络上的其他主机(如pfsense.nailit.lab )。
nslookup vcl.nailit.lab和ping vcl.nailit.lab工作正常。见产出：

ping -a到底是如何解析主机名的？为什么除了'ping -a 192.168.99.3‘以外的所有东西都能正常工作？

ping -a到底是如何解析主机名的？
这叫做反向DNS。转发DNS将名称解析为IP地址。反向DNS将IP地址解析为名称。当您在计算机中键入ping -a 1.2.3.4时，它会发出DNS查询PTR 4.3.2.1.in-addr.arpa。PTR代表指针记录。
为什么除了'ping -a 192.168.99.3‘以外的所有东西都能正常工作？
我的直觉告诉我你丢失了那个IP地址的PTR记录。在您的DNS服务器上，您应该看到所谓的反向查找区域(如168.192.in-addr.arpa )。网络上的所有设备都应该有PTR记录。Windows设备通常尝试注册自己的正向和反向DNS记录，但如果缺少整个反向查找区域，则无法这样做。
