In a network assessment, one of the first tasks is to narrow down a large set of IP addresses to a list of active or interesting hosts. It\'s like trying to find specific houses in a big neighbourhood without knocking on every door. Scanning every possible connection of every single IP address can be slow and often unnecessary. What makes a host interesting depends on what you\'re looking for. For example, network administrators might only care about devices running specific services, while security experts might want to know about every device with an IP address. Imagine a scenario, where a network administrator wants to find all the computers in their office network. They might just want to send a quick signal (like a ping) to see if each computer responds. But if someone outside the network is testing security, they might try different tricks to avoid detection by firewalls and uncover every possible connection. Host discovery serves as the initial phase of network reconnaissance, laying the groundwork for subsequent analysis and exploitation. Host discovery refers to the technique used in a network assessment to find live hosts (online systems) and narrow down the scope of assessment to live hosts only in a network. In this article, we will delve into various ways to perform host discovery in a network using Nmap, netdiscover and angry ip scanner. For this exercise I have used a virtual local area network (LAN) network configured on my local system. The IP range I will use in this exercise is for my network. You have to find your IP before starting a scan for hosts in your LAN. I have used host only as network adapter in my virtual machines, but you can al |
