Many IP address management (IPAM) tools will include some form of IP address scanning but if you choose to take care of that manually, IP address scanning tools can come in handy.
USING ZENMAP MANUAL
Other than security reasons, scanning IP addresses is also the first step of most manual IP address management processes. Unbeknownst to him, the router’s built-in DHCP server started assigning IP addresses from the wrong subnet to computers that were trying to connect to the network. He just needed a couple of extra ports to connect an additional test computer and thought he could use the switch built into his router. I once had this user who prevented many of his colleagues from accessing the network when he connected his home Internet router to it.

They could also be the act of users with perfectly good intentions. They could be devices connected by malicious users to spy on your organization. One of them has to do with detecting rogue devices. But there are several reasons why one would want to do that. It sounds pretty boring and, to be truthful, it actually is.

In a nutshell, a ping scan is the act of pinging each IP address in a given range or subnet to find which ones are responding and which ones aren’t. Finally, we’ll have a look at a few other ping scan tools that you might want to try.
USING ZENMAP HOW TO
We’ll then introduce Nmap, a free and open-source tools with several uses and tell you how to use it to perform a ping scan. And since it relies heavily on ping (who would have thought?) we’ll also give you some background information on the ping utility, what it is and how it works. We’ll start off our discussion by explaining what a ping scan is. Nmap is one such tool and today, we’re having a look at using Nmap for ping scan. When you have more than a few addresses to scan, you better resort to using a specialized scan tool. It is obvious that doing it that way is only practical with the smallest ranges of IP addresses.

Traditionally, this task would be done by issuing successive ping commands and making note of the results. There are, as we’re about to see, many reasons why one would need to do that. Ping scans are typically used to find which IP addresses are in use on a network.
