You can do a port scan on all hosts that you check or just an individual host.
您可以对所检查的所有主机、或者单个主机进行端口扫描。
As described earlier, a single pass of either the host or port scanning information is only useful for the instant in time when the scan was executed.
如前所述，如果只进行一次扫描，那么主机或者端口扫描信息仅在执行该次扫描的时候是有用的。
