tag_summary = "Classifies a host's IP ID sequence (test for susceptibility to idle scan).

Sends six probes to obtain IP IDs from the target and classifies them similarly to Nmap's method.
This is useful for finding suitable zombies for Nmap's idle scan ('-sI') as Nmap itself
doesn't provide a way to scan for these hosts.
