Nmap

[Justin Store <justin.store () mtefcu org>]

Hello,

I'm having issues with nmap reporting different results each time it is run. For example, if run a ping sweep on the 
subnet I will get a different amount of hosts online with each scan. I know my hosts aren't going down and I can even 
ping them using windows. I'm just wondering if you have heard of this or have any ideas as to why this is happening. 
Port scan's are consistent but arp/ping sweeps are not. I was wondering if it was something with my switches since arp 
isn't reliable and tcp is but I don't think it's that either as we have decent managed switches and no other network 
issues. There are only about 40 devices on the network but nmap will tell me anywhere from 20 to ~40. If this question 
is better directed elsewhere, please let me know.

Any insight would be greatly appreciated.

Thanks,
Justin Store
