QoS shaper and class bandwidth

I was hoping to get a clarification on how the QoS shaper works. I'm starting from the example provided in this document.

https://help.ubnt.com/hc/en-us/articles/216787288-EdgeMAX-Quality-of-Service-QoS-#Shaper

set traffic­policy shaper shaper1 bandwidth 100mbit
set traffic­policy shaper shaper1 default bandwidth 60mbit
set traffic­policy shaper shaper1 class 2 bandwidth 20mbit
set traffic­policy shaper shaper1 class 2 match client2 ip source address 10.0.1.2/32
set interfaces ethernet eth0 traffic­policy out shaper1
commit

In this example, I see that class 2 will get 20mbit minimum, and class 2 is defined as 10.0.1.2/32 (a specific IP). If class 2 were changed to 10.0.1.0/24, how would the QoS system respond to that? Would 10.0.1.x get 20mbits minimum as a group, or would each IP have its own 20mbit minimum? If it is not the latter, is there a way to achieve this without specifying each IP individually?
