How to prevent a computer from connecting to a local network on Mikrotik?

Question

Mikrotik

Good morning! I'm putting things in order in the local network of the organization, there are several machines with static addresses that occupy the address space, but no one knows what kind of machines they are and where they are. At the disposal of Mikrotik with, in my opinion, OS version 4. How can I kick them off the local network in order to use their IP addresses?

Answer 1

Because it's all one l2 segment - you won't do anything special on the router.
Only if their access links are turned off on the switches, but I guess you have the dumbest pieces of iron)
Without smart switches, you can:
1. Block the Internet for them and wait for someone to complain :)
2. Depict arp spoofing and wait until someone will complain :) At the same time, take a look at what traffic goes to these machines

Answer 2

If you put things in order, then do not block them stupidly, but still find out what kind of cars and where they are.
Maybe they should be turned off, since everyone has forgotten and lost about them;)
