Relinquish leased /28 subnet?
After 41 years, we've decided to roll up our LLC. The LLC has been dissolved and we've ceased operations. Accordingly, I no longer need our leased /28 subnet.
We're under contract through June 2021; I'd like to know if I can relinquish the subnet and the required Comcast-managed modem, thereby avoiding the associated add-on fees.
