Host probe

Single-target ICMP + TCP/UDP latency probe with hop-count and reverse DNS. Quick 'is this host alive and how far' check before opening an SSH session.

Single-target probe combining:

  • ICMP latency
  • TCP latency (configurable port)
  • UDP latency (where the target responds)
  • Hop count
  • Reverse DNS

Useful for quick “is this host alive and how far away” checks before opening an SSH session.
