Do you need a subnet mask?

As a seasoned expert in the realm of cryptocurrency and finance, I often find myself exploring the intricacies of networking infrastructure that underlie the distributed ledgers and blockchain technologies we rely on. So, I must ask: do you indeed require a subnet mask? This question arises from a fundamental understanding of network segmentation and how it can impact the security, scalability, and overall performance of a cryptocurrency network. A subnet mask is crucial in defining the network address and broadcast address within an IP subnet, allowing for effective routing and network traffic management. Therefore, depending on the specific requirements and design choices of your cryptocurrency network, a subnet mask may indeed be necessary to ensure optimal operations.
