Hi,
we don’t know yet, but maybe on the MainNet it’s important to cover your real node IP.
As an example with PoolTool:
I’ve written a How-To with different scenarios how you “hide” your real node IP behind another machine using ssh-tunnels or via the Tor-Network.
The PDF is available on the PoolTool.io Github repository:

Have fun with it!
