ICMP

ICMP

The default probe sends stateless echo requests with checksum fixups applied by the kernel. Responses are returned as simple reachability signals.

rmap scan --path targets.txt --pps 1000 --timeout 4 icmp \
  --output-file icmp.csv --columns target,alias

Configuration

  • The ICMP probe does not expose additional flags; it respects the shared scan options (--pps, --timeout, --interface, etc.).

Tags emitted

  • alias / alias_prefix – result of the dealiasing engine (aliased, not_aliased, or unknown).

Notes

  • ICMP is rate limited by many networks; adjust --pps conservatively.
  • For IPv6, the probe stores the identifier/sequence in the packet but no additional metadata is exposed.
