nmap + how to detected all machines IP's with range for example 10.64.*.*

How to verify the range of all machines with nmap within IP class
10.64.*.*
For example we tried
nmap -sn 10.64.*.0/24 | grep redhat
in order to capture all machines with redhat name that have IPs from 10.64.1.0 to 10.64.255.255 but this doesn't work.

Is 10.64.*.* a connected network (i.e. the machine from which you're executingnmaphas an IP in the same network)? Is the network subnetmask255.255.0.0(/16)?

Using nmap to scan 10.64.*.*will take a lot of time as there are 4096 addresses to scan.
Also, for OS detection use -O option with nmap.
-sn only shows available host.
You can use -v to see the verbose output.
I hope this helps!!

is it possible to find first the first three octat with nmap ? ( for example in some cluster we have 10.64.30.xxx and 19.64.31.xxx ( is it possible to find it by nmap or other tool ?

If your ip is in the cluster you can check it by ifconfig utility.

Ifconfig utility gives subnet mask. E.g. if my mask is 255.255.254.0 , as it has 23 1’s from beginning. So my ip range would be 10.64.0.0/23 . Try using the verbose output it will solve any doubts itself.

If you're forgoing the port scan, OS detection is likely to be significantly less reliable. Also, you can speed things up further by adding-PRto use ARP to find hosts that are online and-T4to generally speed things up.
