I wasn't thinking about it that way - user messing with user side. My
modem has an html function which allows me to 'look at' its condition;
its status, logs, signal values, addresses, configuration [extremely
simple - see below] and a help section.
The 'configuration' is simply 'North American Standard HRC/IRC' Upstream
channel 1, & favorite frequency. But, the other sections have lots more
information than that.
However, the logs show a lot of 'outside' configuration processes and
enabling and recovering and locking and all that; and the provider
prefers that the modem be left on and accessible from the cable side
because they want to be free to 'mess with' the modem, including
software [and firmware?] upgrades at any time. About the only user type
thing I can see being able to do is 'restore defaults' which of course
goes back to the factory default condition before any of the described

Yes. I call the cable modem IPs 'dynamically static' - because they are
dynamic, but they 'stick' for many many months or indefinitely.
