.SH NAME
nscan \- Network exploration tool
.SH SYNOPSIS
.B nscan 
[ Option ] 
{ target specification }
.SH DESCRIPTION
.B Nscan (“Network Scanner”) 
is an open source tool for network exploration and security auditing. It was designed to rapidly scan single/multiple host(s). Nscan determines what hosts are available on the network.

The output from Nscan is a list of scanned targets, with supplemental information on each depending on the options used. Key among that information is the “ports table”. That table lists the port number and state.
      
In addition to the interesting ports table, Nscan can provide further information on targets, including reverse DNS names.

       A typical Nscan scan is shown in Example 1.

       Example 1. A representative Nscan scan

           # nscan --port 80 scanme.nmap.org
       
           ./main --port 80 scanme.nmap.org
           IP: 45.33.32.156
           Port 80 is active
.SH OPTIONS SUMMARY
This options summary is printed when Nscan is run with no arguments, and the latest version is always available at https://github.com/teobanu21/Port-Scanner. It helps people remember the most common options, but is no substitute for the in-depth documentation in the rest of this manual.
