I can say that in my experience in western Canada it does show up as Canadian, but never in a city in my province. Generally either Winnipeg or Toronto where I assume they've got ground stations.

They could have something to connect their sites, or even tunnel between them over their transit. But if they only have customers on their network, likely behind nat, they don't need to reach each other.
Peer to peer? Self hosted stuff? (not sure how these work with starlink specifically, but - they should work, even if for whatever reason they don't)

#63So, bit of digging, StarLink's ASN is 14593 [1]. They show as having 302 V4 blocks and 59 V6 blocks of space [2]. Some of that space (well, most) looks to be GeoLocated in the US, but some show as other countries. Same with the V6 blocks [3]. My guess is that each V4 block is assigned to a given country or Geo Location, and same with a larger V6. Given they use CGNAT, they wont need as much V4 blocks to split out. If…
Many of Musks companies have access to internal google API's that aren't available to the public. For example, the in-tesla car map uses various google data sources in ways the regular API doesn't support.

That said, you can often still communicate between two NATs using various traversal techniques, although that's generally less likely for carrier-grade NATs, so NAT traversal solutions usually need relays as a fallback anyway.

Probably the coolest answer in this thread! Did Antarctica have any other option for internet, next to the previous gen satellites?
Here at McMurdo we've had 24/7 satellite internet for at least as long as I've been coming down (~10 years). Think roughly a ~30mbps connection shared with ~1000 people with business and science bandwidth prioritized over personal browsing. So starlink has been a game changer for sure. At South Pole, I believe they don't yet have access to starlink. They also don't have 24 hour coverage for the few internet satellite…
Re: Ask HN: How does Starlink work for IP address/ASN internationally?
#66Starlink says on their FAQ page[1] for the roaming model that if you roam too far, your connection will be briefly interrupted while they assign you a new IP address. I think that's because they want every user to have a reasonable experience with all the websites out there that do geoIP lookups. It also gives them flexibility in the future to not act as a worldwide internet backbone for their own users traffic by ad…
> It also gives them flexibility in the future to not act as a worldwide internet backbone for their own users traffic by advertising each set of local IP's only at local POP's. They'd need multiple ASNs for each of these network islands then, though – is their network actually set up like that? > if you roam too far, your connection will be briefly interrupted while they assign you a new IP address.

I think their stated plan is to use laser-links to satellites in higher orbits to do that. Don't know if they'll be bandwidth limited, but there's better latency doing it this way. (light goes faster in the vacuum of space, vs going down an optical fibre)

#67For V2 satellites added sat-sat link, but I have not hear, how large share V2 now, so I think, most links now run in compatible mode.
Other thing, for very long time, AS are classless, mean, they could be registered to any Earth GPS coordinate, but could routed via any peer.
For example, few years ago happen issue, Rostelecom announced ASNs of 90% of EU providers and for few hours, 90% of EU traffic directed via Russian links.
Etc, etc..
