In the realm of networking and specifically IP addressing, could you elaborate on the significance of subnet masks and why they are crucial? Furthermore, as a technology enthusiast and frequent user of computer networks, I'm curious to know - what is the most commonly used subnet mask in today's networks? Is it the Class A, B, or C default subnet mask? Or has there been a shift towards more specific, non-standard subnet masks to better accommodate modern network architectures? I'd appreciate a concise yet informative answer that sheds light on this topic.
