How to get an MAC adress, and that IP?

[Bamsefar]

So I got myself an 2nd hand Velodyne subwoofer. Yes it sound OT. But it is not.

My Velodyne DD10+ has an ethernet port, so of course I connected it to my network with a ethernet cable. The green and yellow LED on the port started blinking, and all seemed to work, except I have no idea which IP adress it uses. Nor do I know what MAC adress it has...

And here is why I post: Is there any way to get hold of an unknown MAC adress, and from that figure out what is most likely a static IP? I know what is connected on my network - so just a (very) long list of all MAC adresses would be enough - then I simply need to figure out what IP it seems to use?!

If you think it’s got a static IP plug it directly into your computer LAN-LAN and run Wireshark to sniff what’s on the wire.
If it’s using DHCP then the router System Logs>DHCP Leases with the longest lease time just after you plug it in (assuming it doesn’t have a lease already).

Or try this from the PC's command prompt.

arp -a

And if you use Apple device, you won’t find a better network tools app than Network Toolbox

For Windows, tools like Angry IP Scanner will display network devices: https://angryip.org/

It's a useful tool but the target must already have a reachable IP address and you need to know which range it's in. The OP doesn't have that information and is trying to discover it.

Ohh Apple - no no not a device I like

I tried "arp -a" - and got the same list as in the web gui for the router (AX88).

So I send an email to the manufacture, well it just swaped owner so in the end I got in contact with the new owner, a Mr Mansour Mamaghani, a very nice and friendly owner - he has among other things let me know that the Ethernet port (RJ45) is not activated (yet? may come in a new firmware maybe if we are nice and all that...). So I will never get anything working there for the moment...

I'd like to thank everyone for helping me with this!
