Network Mapper on turvaskanner mida kasutatakse masinate ning nendes käitatavate teenuste avastamiseks võrgus.

Kõige lihtsam ning ka kõige kiirem kasutusjuht käib läbi alamvõrgu IP aadressid ning ping-ib igaühte:

lauri-e450 ~ # nmap -n -sP 192.168.3.0/24

Starting Nmap 5.21 ( http://nmap.org ) at 2013-08-23 15:37 EEST
Nmap scan report for 192.168.3.1

Nmap scan report for 192.168.3.170
Host is up (0.030s latency).
Nmap done: 256 IP addresses (4 hosts up) scanned in 2.51 seconds

Eemaldades -n võtme tehakse ka tagurpidi nimelahendust:

Küsides iga IP-aadressi kohta tagurpidi nimelahendust võib võrgust tuvastada veelgi mõnda huvitavat, näiteks masinad mis on olnud võrgus veel mõnda aega tagasi:
