What is a 28 subnet mask?
Excuse me, I'm trying to wrap my head around networking concepts and I've come across the term "28 subnet mask." Could you please explain in simple terms what a 28 subnet mask is? I understand it's related to IP addressing and subnetting, but I'm not quite sure how it works or what its significance is. Is it a specific number of bits used to define the network portion of an IP address? How does it impact network configuration and traffic routing? Your insights would be greatly appreciated.
