I am having an issue with a nmap host discovery scan (nmap -sP x.x.x.x/24) that is responding for 0 through broadcast 255 when there are only 30 hosts on that subnet. At this point I am not sure if it is the router or switch that is responding to the ping sweep. What does this usually mean? There is no NAT and no filtering that I can tell, but this is not my forte'... There are other subnets I can ping sweep with no problems... Thanks!
