[C#/OWIN] Where can I create list of banned IP addresses and preload it from SQL for the duration of application?

I was thinking of putting it in Startup class and making the field static. Loading it somewhere in the Configuration() and then wiring up middleware to it.

The design of your application depends on what you want tot do with it. There is no single answer.

  • Must that list change during operation?
  • Is that list shared between different threads?
  • Is this a console application? Winforms? WCF service? WPF????
  • Is that banned list huge?

Nowhere. As soon as you start checking a client's IP Address against a list, you are crippling your application's ability to scale as well as incur a performance hit on every connection.

Move this to a router/firewall.
