help :IP,subnets,broadcast etc

Hello everyone,
I am trying to understand how all this works but right now I am a bit confused. I have done some calculation in finding the solution and need the help of you guys to know wether im doing it right or what i need to do to do it right.
Question:
192.228.17.56 which is on the first subnet of a LAN, and a network address
of 192.228.17.32. List all the subnetworks and broadcast addresses
associated with this configuration

So I have these two IP addresses, because they were similar in the first 3 octet I presumed they belong to Class C 255.255.255.0, but how would I find the mask of an IP address if I only had 192.228.17.56 ?

There are two questions: Finding all the subnetworks and broadcast addresses.
Now I don't really understand what it means "associated to this confifuration" in that context.
but this is what I found:

192.228.17.32 – 11000000.11100100.00010001.00100000
192.228.17.56- 11000000.11100100.00010001.00111000
255.255.255.0- 11111111.11111111.11111111.00000000

The NetID & HostID

Net id: 192.228.17 >> 11000000.11100100.00010001
Host id: 32 >>00100000

Subnetwork: 192.228.17.0 >>11000000.11100100.00010001.00000000
which is the same for 192.228.17.56

Broadcast address:

Broadcast address 1: 11000000.11111111.11111111.11111111 >> 192.255.255.255
Broadcast address 2: same

so thats all I found.

You think this answers the question properly?

thank you
