Subnet range incorrectly explained

What's the problem?

There is a subnet example which reads:

But if I started up a new container set, the subnet would start with 172.28.0.0/16 — notice the “28” rather than the “27”.

And couple of lines later, this is what I read:

In our config, our subnet is defined by the IP addresses 172.27.0.0 - 172.27.0.16. The subnet ends at 16 because the /16 at the end specifies that.

I'm not here to say how it should read like. I think the statement is wrong because the /16 at the end of subnet specifies the bits in the beginning of an address that define the network range, not how big is the actual numeric range for hosts is. The example in the book should give you a range from 172.27.0.0 to 172.27.255.255

How are you reading the book?
