StarLink users
 

Hey - rando question, but I've seen over the last do or so that Starlink users are having their reported locations flapping between US/NZ for NZ users - the IP6 number are the same in access logs, but Azure conditional access is allowing me to interpret the same address differently.

Is that an Azure lookup issue, or a TTL on the SpaceX owned addresses??

Righto chaps.

If, perchance, you configure access in Azure to limit by geolocation, you may want to add :
2406:2d40:4200::/40,NZ,NZ-AUK,Auckland,
2406:2d40:7200::/40,NZ,NZ-AUK,Auckland
...as in-country ranges (or semi trusted depending on how you do it). At present, these switch between US/NZ on various DNS lookups depending on how refined the search is (some higher mask registrations just have US based SpaceX).
