How to use netmask

Introduction

Hello and welcome to another post, today we are going to be talking about the tool already packed into ParrotSec and Blackarch.

Well netmask is an address netmask generation utility as the developer likes to call it, its a great tool in my opinion and today we’ll be going over it and what a netmask is and how to use this tool. I hope you enjoy this post!!

What is a netmask?

A netmask is a 32-bit “mask” used to divide an IP address into subnets and specify the networks available hosts. In a netmask, two bits are always automatically assigned. For example , in 255.255.255.0, “0” is the assigned network address. In 255.255.255.0, “255” is the assigned broadcast address. The 0 and 255 are always assigned and cannot be used.

Netmask defines how “large” a network is or if you’re configuring a rule that requires an IP address and a Netmask, the Netmask will signify to what poriton or range of the network the rule will apply too.

Now to install netmask on your system, I believe you would have to type “apt install netmask” and your done lol.

Now onto using it, lets just type in netmask -h so we can see the commands and now we will do a normal run –

as you can see what got our results, we can use these in further enumeration and scans for more recon. Now lets get the range by running “netmask hackingarise.com -r” okay lets take a look –

and there we go, we have the range! Now lets do a standard run by typing “netmask hackingarise.com -s” lets have a look –

there we go! Results once again..
