Multiple devices are using the same IP address

Support & Solutions Software Issues

For the past couple of weeks, I’ve been getting an alert from our networking gear that multiple devices are using the same IP address.

Version Information

App Version v3.17.4

Firmware Version v3.12.0

I’ve tried restarting both the data center and the core; but after a few days the network alert shows up again.

Example:

Feb 3, 2026 at 09:03:41

Event Type

IP Address Conflict

Severity High

Category System

Subcategory Network

IP Address 192.168.1.154

Network Trusted (1)

Subnet 192.168.1.0/24

  • Clients

    Yarbo Data Center

    Yarbo Core Marvin

  • Description

    Multiple devices are using the same 192.168.1.154 IP address.

Has anyone else seen this issue?

Don’t recall ever seeing any IP conflicts. What is interesting to me is that IP address is also what my core was using prior to rebuilding my network. I see a bunch of randomized MAC addresses with no IP’s periodically and haven’t been able to pin down what causes it. Not sure if that could be related or not.

I think I remember a thread discussing this topic last summer…

I haven’t had a problem myself, but I’m pretty sure someone else brought it up.

I’m also occasionally seeing the long list of random Mac addresses, but haven’t been able to figure that out. Maybe it is related ?

If it is pulling IP addresses, it certainly could be. Do you have an open ticket on both issues? I’d definitely suggest opening one if not.

Yeah, that’s probably my next step. Was going to wait a day to see if anyone else has any thoughts/input.

Some additional context and history plus a few similar ticket numbers for reference.
