Extra MAC addresses

[alancam]

My router has notified me that there are two MAC addresses which it cannot identify.

One is the 2.4GHz one quoted in the status page of the network settings . The other is unknown.

I have tested that this second MAC address is being generated within the SkyQ box. It disappears if I power off  the SkyQ box and reappears when powered on.there are 3 MAC addressese in the network section one for 2.4GHz a second for 5GHz and a third for ethernet (presumably wired connection)

They are 0c:f9:c0:58:51:06 ;  0c:f9:c0:58:51:03 ; 0c:f9:c0:58:51:00

I am getting a connection from 0e:7c:e0:2c:51:02 which  ias not quoted anywhere.

This all started when I tried to filter out intruders from my WiFi using the access list provided.

My router is a Netgear N600  model WNDR3700.

Yeah it does that. Software/virtual NICs.

Thanks for the reply but it was not useful!

What is a virtualised NIC?

Why is it needed and what data does it transmit and to whom?

Bit agressive response to someone who was trying to help you!

A VNIC is a virtualized Network Interface Card, used by a Virtual Machine as its network interface. A VNIC is assigned a MAC address. Each MAC address corresponds with a single virtual NIC, which is used by a virtual machine. You create VNICs when you create a virtual machine.

The point was it did not help to give a glib answer like the one given.

You will note the different name responding as Sky community lost ny details and I had to re-register.

I have been reading other posts about SkyQ box failures and wonder if the extra MAC address is the server for the Mini Boxes? If so it might explain it being there. I have no mini boxes so do not need it.

The point is the system is proprietary and there is no public information about it.

Go ahead and block any unrecognised sources - if it breaks then you may have to allow it.

You seemed like you knew your stuff and would understand it. Otherwise I'm not sure why you'd be fiddling with this stuff?

Yeah I suspect that's what it is but there's no public info. It's possible it's some sort of container or VM that runs streaming apps too.
