Fritzbox - Wi-Fi blocked, can my parents see it?

I'm 15 years old and have a Wi-Fi limit of one hour a day between 6 a.m. And 10 p.m. Now I have seen a Youtube video on how I can get around this block (by changing the last two digits of the IP address to 32 under network settings) it actually worked, only I have in mind that my parents used it on the laptop in the Fritzbox app / program can see.

Do you know about it?

Yes, you can find out.

Yes, the router records when a computer with which MAC and which IP address registered.

Strange that neither a positive list nor a MAC filter was used. The MAC address can also be "spoofed", but much less easily.
