Well, it´s a class A address with 5 bits of subnet (13 - 8 from class A
standard mask). By using the (2^n)-2 rule we have: 2^5 = 32 - 2 = 30.
Don´t forget you can´t assign all 0´s or all 1´s for both the host and the
subnet portion of the address. That´s why you subtract 2 form the 32.
But there´s a trick here: in fact you could have 31 subnets in a Cisco
router if you used the "ip subnet-zero" command, which enables you to use
the zero subnet, although this is not encouraged by Cisco.
So, possible answers for this question would be 30 (most correct) and 31,
but never 32...

This question may find silly for some of you.. Silly
though, I find two different answers in two different
books:
how many subnets the following ipaddress has:
10.8.2.4/13
One book says 32 another says 30
