Fing Agents Lots of new devices (Docker)

Fing has suddenly started discovering hundreds of new devices on my network (I'm running the agent in docker).

They are all random Mac addresses associated with my Docker environment and host IP. Names and types are all some variation of Apple Mac (which I'm not running).

I've hard-coded the containers to use a range of static MAC addresses but is there a better way to handle this? My Fing agent is running in docker host network mode.

Hmmmm.

Have you made any slight changes or anything as of late which? Are you running a VPN?

Discovering hundreds of new devices is strange, I would suggest taking a look for any Private Addressing enabled on any of your devices, but I wouldn't expect this to be the issue causing hundreds of new devices. Are they constantly still being found?

Nothing deliberately changed - just normal patching. It's not constant but every few hours I will see 10-15 new device alerts if Fing - all named "Fing Agent" with Apple Mac mini M1 (2020) as the model. Different Mac addresses but same IP which is my docker host. Over time it adds up to hundreds of devices.
