Hi,

10.1.0.0/22:

/22= 255.255.252.0 so magic number is 256-252=4 so subnet is 10.1.0.0 and next subnet is 10.1.4.0

and so the broadcast is 10.1.3.255 and the range of addresses is 10.1.0.1-10.1.3.254

172.20.0.0/23:

/23=255.255.254.0 so magic number is 256-254=2 so subnet is 172.20.0.0 and next subnet is 172.20.2.0

and so broadcast is 172.20.1.255 and the range is 172.20.0.1-172.20.1.255
