How any free IP scanner cannot improve network discovery
There are plenty of free IP scanner tools out there which are capable of scanning entire IP address space and provide results. There are different tools that use different methods for discovery. But the question is, can we call them discovery tools? And how can any IP scanner improve the network discovery? Those are relevant questions, which I am about to try to answer.
Why should we use free IP scanner
There are a couple of use cases for using a free IP scanner. It usually comes in the form of an application. In the first place, the user needs to install it on his/her computer, which can include a downside. Any application available on the Internet for free can be a potential threat to your system. Of course, there are free available tools that are backed by large communities, created by honest developers from the industry. On the other hand, you should be always careful with the choice of software before installing it.
The good quality free IP scanner can be handy when we try to scan the IP address space usually on a local area network. It can provide you with a piece of information about currently active IP addresses, their DNS names, MAC addresses and more. With this intention, the result will be the list of currently active devices or end-points on a particular network subnet with additional information. One of the good and lightweight tool can be the Angry IP scanner.
Why it doesn’t improve the network discovery
The good point is why it doesn’t improve the discovery? There are a
Second, there may be duplicated IPs assigned to more than one device. That would be definitely difficult to find out by a simple IP scan.
And there can be more reasons. The computer that initiates the IP discovery process doesn’t have access to other network subnets by default. Even though it can be helpful to see active network devices responding.
Complete network discovery process
The complete network discovery process is a time-consuming task that requires a huge amount of data collection and correlation. Given that, it still can be very well automated with tools like the IP Fabric platform.
