Assign ip range to device brand?

Hello,

Is it possible to assign a certain ip range or tag ip-addresses so I can configure specific rules for them?

I have a small cable network, where I want the modems to get an ip (managemnt) in a certain range tto manage them from my management port/pc.

I can’t seem to find any way to to assign a range based on a specific mac-range or device brand.

Can any point me a direction?

Thank you,

Remon
