Take advantage of middleware in ASP.NET Core 6 to check the remote IP address of every request, and allow requests only from known and trusted addresses.

Is there an easy way (like via a .Net library) that allows me to get the IP address and subnet mask of the local machine that the application is running on?

In short, there are numerous reasons why you might need to know the IP address of a machine on your local network. I want to show you how to find that information on most operating systems.
