Hi all,

Does anyone have a good source, or can explain me what is the purpose and use cases of DHCP option 82 ??

I really have a hard time understanding why this even exists...

Thanks,

Mainly to identify the physical or logical termination from where the DHCP packet originated. It's widely used for customer identification in provider/metro networks for example.

This.

I've used it before the only gripe I have with it is various DHCP implementations on CPE. The DCHP on your PC isn't the same type of DHCP on a some home-gateway-vlan-router-switch.
