I'm working on learning how to manually solve some issues related to subnetting.
A practice question I came across states:
If you have a router in the network you're connected to and the Default Gateway is set to 192.168.1.1 and the subnet mask is 255.255.255.0, which of the following are usable IP address on that network?
Just looking at it, I can tell it's not 1), because that'd be a conflict, right?
2) would be too high of a 4th octet
4) is not the right subnet?
What would be the formula to workout the answer? Or is there not one?
I do not know what the MagicNumber would be in this case.
