command terminal output:

nmap -sP 192.168.0.*

Nmap scan report for
Host is up (0.00030s latency).
MAC Address: ... (broadband internet router)
Nmap scan report for
Host is up (0.00016s latency).
MAC Address: ... (computer)
Nmap scan report for
Host is up.
Nmap done: 256 IP addresses (3 hosts up) scanned in 31.54 seconds

route command terminal output (note: personal firewall not disabled at
