OK. I couldn't remember if the Class A B and C settings were just &quot;good practice&quot; or if there were technical issues that they would cause.

Nope, they are just logical groupings for subnets, not rules.

Ok. I have never run into this before, so I have no idea what kind of issues this would raise. I just found a network which has the following setup<br />
192.168.0.0/255.255.240.0.<wbr /><br />
<br />
It has been setup this way, I guess, for years. But apparently there have always been &quot;issues.&quot; though I haven't gotten a clear picture of what they are. I personally have never seen this mistake before, so I am hoping someone can give &nbsp;a quick summary of what kind of problems this would cause.

What happens when you use an inappropriate subnet mask for a Class C network?

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.

Network Architecture

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.
