Orbi Pro WiFi 6 (SXK80) AX6000: Unknown Devices that begin with DEV.
All known devices are defined already. I believe the devices that are unknown are related somehow to the router, i.e. not a device that I have not defined.
At orbinlogin.net, go to Advanced > Setup > LAN Setup > LAN 1 > Address Reservation > Add. A list of devices available for a DHCP reservation will be displayed. The last device listed always begins with DEV. This is the same situation for LANs 2, 3 and 4. Each device is assigned an IP address ending in .1 and each device has an only slightly different MAC address. See attached for an example (only one device in this LAN because it is my Guest LAN).
Does anyone have any idea what this could be?
I understand that Netgear has telemetry in its firmware, enabled by default. Could this be it and if so, how would I disable it?
Thanks.

Yes, under LAN setup, each LAN is 10.0.0.1, 10.0.10.1, 10.0.20.1, 10.0.30.1. DHCP Server range = 2 - 254. I just thought it was odd. Perhaps it is required for the router LANs to function. I was just wondering about it and Netgear support couldn't explain it.
Of course each network resp. each VLAN the router requires an address in the local IPv4 subnet ... so no "perhaps"

So I didn't know if it was related to telemetry. I have been advised to watch out for telemetry being default enabled on Netgear routers.
Of course it's mandatory for the LAN operations 8-)
And of course it should not be listed as connected devices in neither the local Web UI (-> BruceGuo pls.) nor in the cloud with the Insight App or Web portal.

Trying again to get the image to post.
Before of the whatever device name shown there, check the MAC address, specifically the OID. There is a bit which gets set in the OUI portion of a MAC address to signify a randomized / locally administered address. The quick synopsis is to look at the second character in a MAC address, if it is a 2, 6, A, or E it is a randomized address.
So Android (since v8 an option) and many Apple devices (for a year or so) default to random MAC addresses for privacy reasons (intended for public wireless networks primarely). As longas a WiFi connection is defined (on the client) to use random MAC, each connection to a different SSID (network name) will lead to a different MAC address in use.
