My university provides one Ethernet port per student in dorm rooms. They assign IP addresses based on which port you connect to and forbid multiple computers connected to the one port using a hub or switch.

DHCP leases are 24 hours long, but you can switch out 10 different devices with different MAC addresses and keep getting the same IP. How does this work? Do they just figure that if you're using a hub connecting multiple stations to the one port that they don't care if there's a conflict?

How does this work from a technical standpoint? Does the switch act as a DHCP server?

Hello,

The switch will be configured to only allow one IP address to send through it (IP ACL - Access Control List). We cannot help you to bypass this.

If more IP addresses are required, please contact your University's IT department.
