I need help figuring out how to get Nmap to do a ping of a list of computers and tell me which hosts are up and which are not ... including the hosts that do not have DNS entries. Here's my scenario: I exported a list of computers from AD, which I know includes computers that no longer exist. I need to determine which ones are alive and which are not. So I tried this: nmap -sP -iL computers.txt -oA ComputersPing The output is great for telling me what is alive, and even systems that have a DNS entry but are not not up. What it does not do is tell anything about a system that does not have a DNS entry. Because of the use of DDNS, the retired systems are no longer in DNS. Is it possible to get Nmap to output details about the entries in the list that are not in DNS? Norris Carden
I might be missing something here, but what details are you looking for for "retired systems no longer in DNS"? If you have a name for a box but it isn't registered in DNS but the machine is up, you need to get an IP by other means. Can you nbtscan things like 10.1.180.0/24 or 216.76.0.0/14? Otherwise you should consider exporting ARP tables from your routers.
