how to scan all host in network use nmap

To scan all hosts in a network using nmap, follow these steps:

1. Open a terminal or command prompt on your computer.

2. Type the following command:

   nmap -sn <network_address>

   Replace <network_address> with the IP address of the network you want to scan. For example, if you want to scan all hosts in the 192.168.1.0/24 network, you would enter:

   nmap -sn 192.168.1.0/24

3. Press Enter to run the command.

4. Wait for nmap to complete the scan. This may take a few minutes depending on the size of the network.

5. Once the scan is complete, nmap will display a list of all hosts that responded to the ping request. This list will include the IP addresses and MAC addresses of each host.

Note: Depending on your network and security settings, you may need to run nmap as root or administrator to access all devices on the network
