Introduction

A Port Checker is a software used to scan open ports on a specific network. Port scanning is used for many different purposes. On a very basic level, they are used to determine whether or not a port is opened to receive the data or not.

These types of programs are used by big companies through their software programmers and network administrators for various purposes which can range from basic troubleshooting to identifying security loopholes. They can also be used by an everyday user to scan their own network to find any kind of vulnerability before a red hat finds it.

They are the best tools for identifying security risks and for testing out network security. It can detect whether or not there is a firewall in place in a network and most of the time they use TCP protocols. Today we have brought you some of the best network port checkers out there.

How to Scan a Port

Port scanning involves five different steps:

  • First, you need to have active hosts. You cannot scan a port without active network hosts. Network scanning can discover it.
  • Map the active hosts to their IP addresses to trace
  • The third step involves sending packets to the concerned ports on the host network to see if everything is working and if the ports are opened
  • The fourth step involves a detailed analysis of your raw data
  • Then, with all the data that you will receive regarding the running services of the network, you will be able to identify the potential vulnerabilities

The advantage of these port scanners is that they are able to connect to a wide range of IP addresses and ports. Furthermore, they provide different types of port scans which include, but are not limited to, TCP scans, Stealth scanning, Basic scans, etc.
