What is wrong with this IP address - and why?

This is the IP address in question.

172.16.254.160/27

I know that it is a network address, but what I'm struggling to do is to understand how to work that process backwards. Or basically, how you'd explain that you'd look at that address and be able to explain WHY it's a networking address.

I know how to discover the subnet mask, broadcast address, network address, etc, from an IP, but I'm really struggling to find any sources on how to properly articulate how you explain "This is actually a networking address for x reasons."
