comment Nmap: find free IPs from the range
@Grant Nmap's host discovery scan (sometimes called "ping scan") sends lots of different probes, not just ICMP Echo Requests. For addresses on the same data link, it uses ARP requests, which are basically impossible to ignore.

comment Nmap: find free IPs from the range
When run with root privilege, Nmap simply does the ARP request and reports addresses that respond.

comment DDOS using ntp server
Security folks can use Nmap's ntp-monlist script to find offenders on IP addresses they own. An ISP can check its own AS with this command: nmap -sU -p123 --script ntp-monlist,targets-asn --script-args targets-asn.asn=1234,newtargets --open -oA ntp-results

comment nmap lists host as up despite being black listed
@Craig As I mentioned in the first sentence, you are telling Nmap not to even try to discover the host, but to assume it is up. Therefore it says "Host is up" because it believes you. Remove the -Pn and add --reason, then continue your testing.
