How to use IP ranges in Nmap?

You can use IP ranges in Nmap by specifying the range in various formats. Here are a few examples:

Using a hyphen (-): This allows you to specify a range of IP addresses.
```
nmap 192.168.1.1-10
```
This command scans the IP addresses from 192.168.1.1 to 192.168.1.10.
Using CIDR notation: This allows you to specify a subnet.
```
nmap 192.168.1.0/24
```
This command scans all IP addresses in the 192.168.1.0 subnet (from 192.168.1.1 to 192.168.1.254).
Using a file with a list of IPs: You can create a text file with a list of IP addresses and use the -iL option.
```
nmap -iL targets.txt
```
Here, targets.txt contains the list of IP addresses you want to scan.
Combining ranges: You can combine multiple ranges or individual IPs.
```
nmap 192.168.1.1,192.168.1.5-10,192.168.1.20
```
This command scans 192.168.1.1, 192.168.1.5 to 192.168.1.10, and 192.168.1.20.

These methods allow you to efficiently scan multiple IP addresses or ranges using Nmap.
