Why would LEO satellite internet cause frequent change of IP addresses? Shouldn't all that moving-satellite stuff be handled on a lower level of the OSI Model (probably Layer 2: Data Link), and the IP stuff at Layer 3 isn't affected?
- dreamcompiler 3y agoWith Starlink, the downlink location determines your externally-visible IP address and that can change every 90 seconds or so based on where the closest satellite to you is at the moment. I'm in New Mexico and I frequenly see ads on web pages directing me to shops in Denver or Dallas because those are the downlink locations for me. You can see the issue better on this visualization: https://starlink.sx/ https://starlink.sx/
- jey 3y agoOK that's strange but makes sense, so it's the publicly-routable IP after "network address translation" (NAT) that keeps changing.
- olyjohn 3y agoI think there must be something going on here. Changing your IP address would screw with all sorts of things. You never be able to do online gaming. Video streaming would stop working every time your IP changed. Anything that streams would just die and not recover for a while.
