I run a network with 50,000+ end users using ethernet-based access to the
user's room. In IPv4, I run 1 or more subnets per building (depending on the
number of rooms in the build). I use DHCP to assign IPs, and record the
DHCP assignments allow me to trace users in the event of abuse complaints. I
use DHCP Option82 to allow me to correlate multiple devices in a user's room.
I feed the DHCP information into my bandwidth management platform to enforce
different levels (i.e. speeds) of service per user depending on what they've

For IPv4, I use DHCP to
