If you have time to scan such a class C again, how does Nmap 3.78 do with "-T4 --min_hostgroup 256 --max_scan_delay 0 --max_rtt_timeout XXX" (where XXX is about double the average ping time against hosts on the target network). How does that compare to 3.55?Nmap-3.78 wins here but generates much more traffic. When scanning less than 25 hosts paralelly, nmap-3.55 wins.
Correction - nmap-3.78 looses in all cases when ICMP rate-limit is implemented C-wide - e.g., there is a single firewall in front of the whole C block. Paralelisation doesn't help here.
