I know when I share my phone's mobile internet to my laptop through WiFi tethering, the two devices are in the same network and can see each other. But how do I find out the local IP address of the other device?
After a little bit of Googling, like this:
nmap -sn 192.168.2.87/24
-sndisables “port scan”, which I assume means nmap will scan for devices and not scan for open ports.
- The IP comes from the
inetfield in my WiFi device that I got from a call to
This is the result:
Starting Nmap 7.92 ( https://nmap.org ) at 2022-03-15 01:53 JST Nmap scan report for 192.168.2.87 Host is up (0.00024s latency). Nmap scan report for 192.168.2.169 Host is up (0.0059s latency). Nmap done: 256 IP addresses (2 hosts up) scanned in 6.48 seconds
This means it has found two devices on the local network:
- 192.168.2.87, the device I ran the command on;
- 192.168.2.169, the only other device on the local network, so it's the device that I'm looking for.
ip address returns, with irrelevant parts removed:
