The second field is 0 if the result is pending and may be ready in the future or 1 if the result is ready now. If the second field is 0 the remaining fields should be 0. Otherwise the remaining fields contain the IP's latitude, longitude, and X/Y/Z coordinates. ZeroTier's cluster route optimization code only uses the X/Y/Z values. These are computed by this cluster-geo code as the spherical coordinates of the IP address using the Earth's center as the point of origin and using an approximation of the Earth as a sphere. This doesn't yield *exact* coordinates, but it's good enough for our purposes since the goal is to route clients to the geographically closest endpoint. |
