🗺️ If you’re looking specifically for geo-location of relays:

Unfortunately, no public tool yet offers full relay mapping by geographic location with filtering. But here’s a workaround:

🔧 Manual Option:

Use https://nostr.watch, then:

1. Take relay domain/IP.

2. Use tools like IPinfo.io or iplocation.net to check physical server location.

3. Use the result to filter for geographic diversity yourself.
