How do Starlink IP addresses work with Geolocation? Does Starlink have access to IP address blocks for all coutnries and issue them out based on registration and/or GPS data? Or do all starlink customers worldwide get issued US IPs?
An interesting problem - I wonder what they truly do here. I suppose people expect interruptions with Starlink so doing an IP swap wouldn't be all that different to losing service due to obstruction for a few minutes.
Everything retries cause there isn’t difference between new address or bad connection. Most of time we don’t notice cause not using device. Or because most connections are short lived.
Your comments are more practical (and maybe aimed at a layman's use of Starlink) but I am talking about the theory of Starlink supposedly interrupting a perfectly-working connection in order to change your IP, which interrupts everything, by design of TCP/conntrack. Whether that operation is fatal or not due to retries or whatever else is not my point at all.
Also, ISPs at home don't randomly disconnect you to give you a new IP. They may give you a new IP when you disconnect and reconnect for other reasons, but they should never dump your connection on purpose just to give you a new IP for no reason. That's not good design at all, hence the question about how Starlink handles wanting to give you a new IP.
What I do know is our IP changed depending on our geographic location.
If I had to guess, you probably get the address of the base station whose signals reflect off the satellite, which is probably not very far from you, given the satellites are in LEO.
EDIT: I meant to say that you get an address in the ground station's subnetwork. I don't know if Starlink uses NAT.

Also, people in Europe don't want to have to take a round trip to space via America just to pull up IKEA's website hosted next door. That's a lot of pointless latency when you could bounce it down to a nearby ground station instead.
Starlink, in particular, reports their base station locations: https://geoip.starlinkisp.net/feed.csv
Sure there are. IP addresses assigned to an organization with a US address (typically by ARIN) are US IPs. Of course, there's nothing that requires those IPs to be used exclusively for destinations inside the US.
