n ping

Fast reachability radar (<300ms) or Who Am I loopback

Usage — n ping

═══════════════════════════════════════════════════════════════════════════════
  Netscrew ("n") — ping (pi, radar) — Fast reachability, or a who-am-I of this machine
═══════════════════════════════════════════════════════════════════════════════

USAGE:
  n pi .                               who am I: local NICs, gateway, Tailscale, hosts file
  n pi <host>                          reachability radar (latency, TTL/hops)

Target: . = this machine · <host> = remote
Deeper: n pi -h = the concept/theory behind this command

The concept behind it — n ping -h

OVERVIEW:
  n ping is your all-in-one network discovery and reachability engine.
  It intelligently adapts to the target you provide:

CAPABILITIES & USAGE:
  • n ping                       Host "Who Am I" audit: inspects all local adapter
                                  IPs (physical, virtual, Tailscale), WSD/mDNS/WINS discovery
                                  protocols, and static /etc/hosts file validation.
  • n ping 192.168.1.0           Subnet sweep: concurrent probes across all 254 hosts
                                  in <2s with NetBIOS names, reverse DNS, MAC vendor & archetypes.
  • n ping 192.168.1.10 50       Scan specific IP range (also: n ping 192.168.1.10-50).
  • n ping <TARGET>              Single host reachability with automatic diagnostic fallback
                                  and Layer 2 ARP troubleshooting if the host is unreachable!

FLAGS & TUNING:
  • -u, --ignore-unresolved   Show only devices with successfully resolved hostnames
  • -t, --threads <NUM>       Maximum concurrent scan workers (default: 100)
  • -w, --timeout <SEC>       Probe timeout in seconds (default: 0.5s)
