How can I use cidrmatch or case using 2 conditions?

Example: I only want to get list of IPs where row_A is 11.0.0.0/24 and row_B is 8.8.8.0/24

Current Table:
row_A row_B
10.0.0.1 11.0.0.1
10.0.0.2 12.0.0.1
11.0.0.1 8.8.8.8
11.0.0.2 8.8.8.9
12.0.0.1 8.8.8.8
12.0.0.2 8.8.8.9

Target Result:
row_A row_B
11.0.0.1 8.8.8.8
11.0.0.2 8.8.8.9

Thanks!
