help :IP,subnets,broadcast etc

[cpu2007]

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

The netmask is part of the IP configuration for the interface. You can't just guess. With that broadcast address, this looks like a class A network. How come you don't have the netmask information?
