Create 30 subnets from the following starting address: 175.19.40.0/21

1. Write out the new subnet mask in dotted decimal format
2. Write out the new subnet mask in dotted decimal format

I'll be honest I already googled the question and the first answer (it's on course hero) is apparently 255.255.255.192 but how is that even right? Wouldn't that only give you four subnets?
