IP Math anyone?

[Sandipan Gangopadhyay]

Actually, not only .0 or .255, could be any other IP address as defined by
the netmask in sub-nets.

Eg, .184 is similar to .0 (network address) if netmask is 252 instead of 0
Similarly, .187 is similar to .255 (broadcast address) with this netmask.
In other words, 252 delivers a 4 address sub-net.

Therefore the maths operations will have to involve the netmask.
