4 Examples of Network Scanning for Live Host

Hi there, I am happy to see you on my blog. In this article, I am going to discuss the 4 Examples of network scanning to check live host. if you want to check out your target system then it is your first step to getting the information that target machine is live or dead. Live or dead means here “system is on or off, IP exists or not”

What is Nmap?

“Nmap is best network vulnerability scanning software or one of network security audit tools used to scan LAN network. In this article, I will use Nmap network scanner to scan the network.” It is a free network discovery software. 

Method 1: Ping Scanning for live host

Ping command is used to check the connectivity between the hosts in network. It sends an ICMP packet containing 8 and 0 code indicating this packet is and echo request. Target received this packet and response with another ICMP packets contain 0 code indicating an echo reply. A successful Ping and response would show that the System in a network to be a “Live Host”.

Method 2: Ping Sweep Scanning 

A ping sweep (otherwise called an ICMP sweep) is a fundamental system scanning strategy used to figure out which of a range of IP address guide to live hosts (Computer). Although a single ping will let you know whether one specified host machine upon the network, a ping sweep comprises of ICMP (Internet Control Message Protocol) ECHO requests sent to multiple hosts. In the event that a given address is live, it will give back an ICMP ECHO response. Ping sweeps are among the more seasoned and slower strategies used to scan a network.

There are various tools that might be used to do a ping sweep, for example, fping, gping, and nmap for UNIX platform.

Namp is free network port scanner tool used for scanning and test security. it is found out network vulnerability.

Method 3: IP Address Scanning Within Ranges

Characterizing a set of targets utilizing an IP address range is truly nice. And scanning network is handled by IP address scanner nmap.  For this example, the address will be the 192.168.56.x class c address range. This will mean that the greatest number of has that might be incorporated in the sweep is 254. To output, the greater part of the hosts, utilize the following command.

#nmap -sn 192.168.56.100-150

This same sweep might be finished utilizing the CIDR method for addressing to by utilizing the/24 postfix as takes after.

#nmap -sn 192.168.56.0/24

Method 4: List Scan by using nmap

Nmap can additionally utilize a content record as info for the target list. Expect that the following addresses are put away in a document called targets.txt.

192.168.56.100

192.168.56.103

192.168.56.110

192.168.56.115

The scanning can be performed by using given command

#nmap –iL /Location_Target.txt
