2.12　反向域名解析表2.11所示为本章节所需Nmap命令表，表中加粗命令为本小节所需命令——反向解析域名。

-R选项意为反向解析域名，使用该选项时Nmap永远对目标IP地址作反向域名解析。 root@Wing:~# nmap -R -sL *.172.156.75/24 Starting Nmap 6.40 ( http://nmap.org ) at 2014-06-09 21:29 CST Nmap scan report for *.172.156.0 Nmap scan report for *.172.156.1 Nmap scan report for *.172.156.2 Nmap scan report for *.172.156.3 Nmap scan report for *.172.156.4 …省略… Nmap scan report for mail.***testarlight.com (*.172.156.229) Nmap scan report for *.172.156.230 Nmap scan report for *.172.156.231 Nmap scan report for *.172.156.232 Nmap scan report for *.172.156.233 Nmap scan report for *.172.156.234 Nmap scan report for *.172.156.235 Nmap scan report for *.172.156.236 Nmap scan report for *.172.156.237 Nmap scan report for *.172.156.238 Nmap scan report for *.172.156.239 Nmap scan report for *.172.156.240 Nmap scan report for *.172.156.241 Nmap scan report for *.172.156.242 Nmap scan report for *.172.156.243 Nmap scan report for *.172.156.244 Nmap scan report for *.172.156.245 Nmap scan report for *.172.156.246 Nmap scan report for *.172.156.247 Nmap scan report for *.172.156.248 Nmap scan report for *.172.156.249 Nmap scan report for *.172.156.250 Nmap scan report for *.172.156.251 Nmap scan report for *.172.156.252 Nmap scan report for *.172.156.253 Nmap scan report for *.172.156.254 Nmap scan report for *.172.156.255 Nmap done: 256 IP addresses (0 hosts up) scanned in 4.41 seconds root@Wing:~#

通过上述代码可以看到Nmap对*.172.156.229进行了反向域名解析，其他IP地址并没有绑定域名。该选项多用于绑定域名的服务器主机上，该选项的使用便于我们了解目标的详细信息。例如，在扫描一个C段的时候，我们更加清楚在哪一段IP上存在哪些网站。
