Internal Infrastructure Pentest - Nmap Ping Sweep

less than 1 minute read

  • Ping sweep is the process of pinging an entire range of network ip addresses to find out which ones are online or alive. Nmap is an excellent tool to do this quickly and effectively.

  • nmap -sP 192.168.1.1-255

  • nmap -sP 192.168.1.1-255 -n
    • “-n” flag will disable dns resolution.
  • nmap -sP 192.168.1.1-255 -n –max-rtt-timeout 50ms
    • Using lower roundtrip times, the accuracy may reduce, since some hosts may reply after the timeout and nmap won’t be able to catch their replies.
