This is really impressive, and the visuals are great.

I'm curious about the self hosted part (at least for LN purposes) ... getting things like the ISP (Amazon, Google, etc) requires some sort of external IP address lookup service.

This data is not available on a new Lightning Node or a part of the network gossip - a third party would be needed to retrieve this data historically or on an ongoing basis.

Has anyone tried this on a local machine, docker instance, etc? Is the service making a local call from the node to some sort of IP lookup service?
