[ASK] Checking Ip Range using NMAP

Dear Master

I am a newbie for using nmap. I want to ask if i want to scan ip range from this:


using nmap and with this code Many this code not working as they say no host found or proxy.. my question are what code to write in nmap so i can know what iport that a live? what my expetation are this code will gave me result like this [example] : 123.55.244.80: 80 or 8080 or 18123or etc.
Second question its nmap are best software for doing this because i tried to searching using nmap and found sometimes it take a lot of time to scanning some 1 proxy. (more than 1 hour). I doing this scan using wifi connection not using vps or server host.

Thank you

a range of that size should take a few mins on tcp scan
problem is knowing what port number to use or it or the rest
is a waste

Thank you for your respond. So what code i should use? or any tools that i can doing to make simple for me?

You would use a code like this -
It will scan from 127.0.0.0 to 127.0.0.255.

Is nmap multi-threaded? Not sure but if it's not, that should be the problem.
Also i will only search for the ports that are commonly used for proxy and not search the whole range.
I use angry IP scanner and it is pretty fast IMO. Never really tried NMAP so can't say..

Totally agree with you about Angry IP Scanner, I use both but if I need some real fast scanning then I use Angry IP Scanner, I use nmap for few other reasons, one of them is OS identification and etc...
And it's easy to scan multiple ranged with it.

There is a previous version of AIS ( 2.13 or something do not remember) which also detects OS, MAC ID etc. Just increase the columns from settings.

Thank you for your respond. In fact i already used thats code, but sometime it nothing to show and with result the host are down.. but when checking using code like this:
it will show host up so i think nmap its not multithread...

-g0g0l thank you to for the information.. if angry Ip scanner can doit multihread? i will check it. thanx

Yes dude it's multi-threaded and I run 100-150 threads without a problem.
