How many subnets can be gained by subnetting 172.17.32.0/23
into a /27 mask, and how many usable
host addresses will there be per subnet?

Answer Posted / robert davenport

I have one bit of clarification on my answer. As the IP
address of, 172.17.32.0, was given that will reduce the
amount of subnets. The third octet (.32.) has restricted us
to one subnet on the /23 prefix. so that will change the
total subnets for the /27, see the following:

Prefix Subnets in Hosts per
Length Range Given Subnet
/23 1 510
/27 14 30

So, the Subnets will increase by 13 and the hosts will drop
to 420 (14x30). Hope I got it this time.
