Weird ip address in microtit?

Question

Mikrotik

Good afternoon. It is not clear where one ip came from, which is updated every 30 seconds. If you remove it from DHCP, then it all appears exactly. He doesn't ping. There are a lot of messages on this IP in the logs of Mikrotik. IP - 192.168.0.34
What is it and how to remove it?

Answer 1

For some reason, your device does not want to accept the address from Mikrotik. Either something is wrong with it, or you have a second dhcp server on your network

Answer 2

Judging by the poppy, this is some kind of camera from Vivotek. It asks the DHCP server for an ip address, but for some reason the answer from it does not reach the addressee:
- either the camera is not working properly
- or you have several DHCP servers on the network
- or dhcp-snooping is enabled on the switches, but configured crookedly.

Answer 3

Try blocking the MAC address

/ip firewall raw
add action=drop chain=prerouting src-mac-address=ff:ff:ff:ff:ff:ff comment="MAC_ADDR_BLOCK" in-interface=bridge1 disabled=no

Submit your details

Answer 4

What is the question? How to find this device?
What is your network? Are the switches worth it? Does the WiFi work?
