thanks

am on Mac OS El Capitan

tried ipconfig but I guess the Mac version does not include /all

router is leased from Whidbey Tel and they do permit end users to log in to the router

but

riddle is solved

I crawled up into the ceiling, unstrapped the ADT Pulse Gateway, turned it over, and what did I find

in teeny tiny letters "by Netgear of California" with a MAC address that matches

so

when Fing, etc report IP and MAC by Netgear, they are correct

they are referring to the ADT Pulse device, NOT the Netgear switch

so riddle is solved, thank you all

Hello engravosurus, 

Welcome to the community! 

The FS105 is only a pass-through switch therefore,  it does not need an IP. It could be that the IP address that you are seeing is assigned to the first device connected to it. All it does is to forward packets by remembering MAC addresses of the devices which transmit and request packets. For more information, please click here. 

I hope the information helps if you have more questions the community is happy to help. 

Thanks,

thank you

netgear has 3 cables

1 input from a linksys switch

2 output to jack in the storage room which is empty

3 empty

4 empty

5 to ADT alarm systemwifi

Hi engravosaurus,

Is the Linksys switch a manageable switch?  If yes, then possibly the IP address you see belongs to the Linksys switch.

so I unplugged the ADT alarm wifi device

then the Netgear IP went at away

perhaps the IP belongs to the ADT device but the system cannot figure that out so assigns it to the last thing it recognizes

Hi engravosaurus, 

Just like what I have thought, did your router list the IP with the FS105's MAC? It could be having a hard time recognizing the devices plugged in to it or probably have something to do with the other switch which feeds the FS105. 

Let us know if you have more questions. 

Thanks,

newbie but I think not manageable

[engravosaurus]

yes Netgear MAC address

should now abort as I know more than I need to but tis fun

how do I show IP, MAC and vendor (all 3) of all devices on the network

the various apps I have tried do not show everything in one place

and tried ifconfig and arp

[engravosaurus]

but then I find unmanaged switches have no MAC address so maybe the end

thank you all

Hi engravosaurus,

On a Windows PC, the command "ipconfig /all" (without the quotation marks) executed via the command prompt will display full configuration information. 

On the web-GUI of the NETGEAR ProSAFE VPN Firewall routers, there is "LAN Groups" wherein it shows all the IP addresses and the corresponding MAC Addresses that are connected within the local network.  Have you check the web-GUI of your existing router if there is "LAN Groups" or "Attached Devices"?

thank you

am on Mac OS El Capitan

ipconfig /all returned simply parameters for ipconfig; I guess no /all parameter

router is from Whidbey Tel and they do not permit "simple" end users to log in

should give up, move on

but would be fun to see list of IP, MAC and vendors
