Additional Logging Configuration Question

I was in the process of configuring logging for a k8s cluster to an internal elasticsearch cluster when something crossed my path in the configuration that has me scratching my head. At the bottom of the configuration window is an “Additional Logging Configuration” section and on the right side of that section is a window with some markup in at that can’t be edited… and I don’t even know what it’s for. I’m attaching a screenshot to show the part I’m referring to. This IP seemed to trace to Hong Kong, and now I’m just curious what is going on with the information in this window / what that IP (and master_url too) is even used for. Nothing in the rest of my configuration has anything related to this bits.
