3.利用ping命令（-a參數(shù)）獲取計(jì)算機(jī)的NETBIOS網(wǎng)絡(luò)名稱

在知道目的主機(jī)的IP地址的前提下，利用帶有-a參數(shù)的ping命令可以獲取其NETBIOS主機(jī)名稱，其結(jié)果在運(yùn)用ping命令后的第1行返回。

例如：

            C:\WINDOWS>ping -a 192.168.1.100
            ping ing abc [192.168.1.100] with 32 bytes of data:
            Reply from 192.168.1.100: bytes=32 time<10ms TTL=128
            Reply from 192.168.1.100: bytes=32 time<10ms TTL=128
            Reply from 192.168.1.100: bytes=32 time<10ms TTL=128
            Reply from 192.168.1.100: bytes=32 time<10ms TTL=128
            ping statistics for 192.168.1.100:
            Packets: Sent = 4，Received = 4，Lost = 0 (0% loss)，
            Approximate round trip times in milli-seconds:
            Minimum = 0ms，Maximum = 0ms，Average = 0ms

可以得知，IP地址為192.168.1.100的計(jì)算機(jī)的NETBIOS網(wǎng)絡(luò)名稱為“abc”。

再如：

            C:\WINDOWS>ping -a 192.168.0.23
            ping ing 9.localdomain [192.168.0.23] with 32 bytes of data:
            Reply from 192.168.0.23: bytes=32 time<10ms TTL=128
            Reply from 192.168.0.23: bytes=32 time<10ms TTL=128
            Reply from 192.168.0.23: bytes=32 time<10ms TTL=128
            Reply from 192.168.0.23: bytes=32 time<10ms TTL=128
            ping statistics for 192.168.0.23:
            Packets: Sent = 4，Received = 4，Lost = 0 (0% loss)，
            Approximate round trip times in milli-seconds:
            Minimum = 0ms，Maximum = 0ms，Average = 0ms

可以得知，IP地址為192.168.0.23的計(jì)算機(jī)的NETBIOS網(wǎng)絡(luò)名稱為“9.localdomain”。
