Is there software on the Internet for scanning IP addresses on a local network, with a memory function?

Question

Computer networks

A bunch of laptops on different floors, which have changed hands more than once. There is a plan to draw a map of the enterprise, and walking to see the ip of each is suicide. Is there a "softina" for scanning and creating a database of ip addresses?

Answer 1

nmap what could be better

Answer 2

I like Network Scanner .

Answer 3

I use the dude ( tyts ).
A very cool program that has a server part and a client part. With due skill, it can compete with Zabbix. Able to detect devices and services on it, by mask.

Answer 4

For scanning under win I usually use www.advanced-ip-scanner.com

Answer 5

arpwatch
By default, it sends out letters, but it can be configured to write to the database, there is also a web server (and more than one).

Answer 6

Someone ate traffic in my local network.
At first I used iftop - the manual in English is very simple and understandable, I immediately threw in a config for it.
Further, I calculated the ip that it was eating, and only nmap could tell me everything about it - it turned out to be a router with a free Wi-Fi for clients in the reception. Other scanners failed to scan the router.
