when Im trying to run a zombie scan using an idle machine with the ip of 10.0.0.10, to scan the ip of 10.0.0.31, I get some odd errors.

Here's the command I'm using: nmap -PN -sI 10.0.0.10 10.0.0.31 * exec: nmap -PN -sI 10.0.0.10 10.0.0.31

which gives me a bunch of errors like this

Failed to resolve given hostname/IP: plugins. Note that you can't use '/mask' and '1-4,7,100-' style ip ranges
Failed to resolve given hostname/IP: README. Note that you can't use '/mask' and '1-4,7,100-' style ip ranges
Failed to resolve given hostname/IP: scripts. Note that you can't use '/mask' and '1-4,7,100-' style ip ranges
Failed to resolve given hostname/IP: test. Note that you can't use '/mask' and '1-4,7,100-' style ip ranges

etc etc etc.......
Im new so take pity on me

Thanks
