My local network is 10.0.0.1 - I have an external device that is pre-set from factory to 192.168.1.100 and I need to access to it via browser to change its network setting. So I do: ifconfig net0:1 192.168.1.1 up
nmap -sn 192.168.1.1/24 Starting Nmap 6.47 ( http://nmap.org ) at 2017-02-12 00:54 MST Nmap scan report for 192.168.1.100 Host is up (0.00015s latency).
