RefCheck.Radio sends UDP connection packets to each reflector registered on
DVRef.com for each mode, every ~1 hr.
The timeout is 5 seconds; the service attempts the connection twice before listing
a reflector as unreachable. The page auto-refreshes to reflect the latest data.
Each reflector's IP is also checked against commercial hosting
provider ranges: ✓ indicates a commercial/hosting IP,
✗ indicates a home/residential IP.
This is not a "wall of shame" -- it is a resource for
both reflector users and operators to help make Digital Voice for Amateur Radio a Better
Place™. 💙
