When I use this command which IP addresed are scanned
# nmap -sP 192.168.0.120/25
CAn you please help me how to get the IP range when I have the addres and subnet. Because I am trying to understand this, but no result till now..Thanks in advance

I would use a web service that can return JSON (along with jQuery to make things simpler). Below are all the active free IP lookup services I could find and the information they return. If you know of others, then please add a comment and I'll update this answer.

Limitations:
With modern browsers, you can use the native Fetch API instead of relying on jQuery's $.getJSON()
. Here's an example:
let apiKey = '1be9a6884abd4c3ea143b59ca317c6b2';
// Make the request
fetch('https://ipgeolocation.abstractapi.com/v1/?api_key=' + apiKey)
// Extract JSON body content from HTTP response
.then(response => response.json())
// Do something with the JSON data
.then(data => {
console.log(JSON.stringify(data, null, 2))
});

request header"That's Classless Inter-Doman Routing notation. The /24 means that the routing prefix of the subnet is 24 bits long, which means there's ony 8 bits left for the subnet itself, i.e. 123.218.44.0 to 123.218.44.255
Best Answer
The network in your command is in CIDR notation. The first part (before the
/
) defines which network, and the second part defines how many bits of netmask are set. An IPv4 address is 4 bytes, or 32 bits of information./25
means that 25 bits of this address are used to denote the network, and32 - 25 = 7
bits are left to address hosts on the network. A/25
network can hold2^7 = 128
hosts, less the network and broadcast addresses. To get the network address (the start of your block of addresses), you take the address given and bitwise-and it with2^32 - 2^7
. In this case (using Python):So the network address is
192.168.0.0
, and you have 128 addresses, so your target range is 192.168.0.0 - 192.168.0.127.
