[NEBULA] WiFi Device Descriptions - where is the source?

HealthByRo

Can someone shed some light on where the WiFi device descriptions are "read" from, what is the source?  In particular on a Mac?  And on a Windows PC?   We'd like to adjust the source so that the list of devices helps us determine which computer it is.  Any suggestions on where to look is appreciated.

Hi @HealthByRo

I suppose the mac address could partially determine it.

Some web pages provide information from the mac address.

For example macvendors.com 

Does it help you?

Sorry. not exactly what I was looking for.  There must be somewhere that the AP is reading that name from, and when it doesn't find it, then the MAC address is used in the description.   I wanted to standardize that to something.  Right now there are a few devices with something that is definitely user-entered.

As far as I know and based on my network, the AP and GW will try to get the hostname of the device, I guess it's from the DHCP packet.  If not, it will use the MAC-address.

Cheers!

Hey guys, 
@RUnglaube is correct, the hostname/description you'll see in NCC is from DHCP packets, most of modern devices has it's hostname stored in DHCP packets on option 12.

So the response is from the DHCP server?  Or from the user computer?

AP/Gateway listens from the client device, packets from gateway won't carry the clients hostname and other attributes in them, then is reported to NCC.
