Testing location data with edge cases, not just happy paths
An address in a well mapped city center tells you almost nothing about how your system handles a rural route, a disputed border, or a query near the poles. Test the hard cases deliberately.
How satellite internet ranges complicate IP geolocation
Most fixed internet connections have a fairly direct relationship between a subscriber's physical location and the geographic area their IP address is registered to, because traffic enters the wider internet at a regional point relatively close to where the connection physically originates. Satellite internet breaks that relationship in a way worth understanding if you are geolocating traffic that comes from it.
A satellite connection routes a subscriber's traffic up to a satellite and back down to a ground station, which is where the connection actually joins the terrestrial internet, and that ground station can be a considerable distance from the subscriber, sometimes across an entire country or region, depending on how the network operator has built out its ground infrastructure. The IP address a subscriber uses is typically tied to that ground station's location or the operator's registered address block, not to wherever the subscriber's dish or terminal physically sits.
The practical result is that IP geolocation for satellite internet users tends to be considerably coarser than for typical fixed or mobile connections, sometimes resolving no better than to the broad region a particular ground station or operator block serves, especially for satellite services that cover large geographic areas from a comparatively small number of ground stations. This is not a shortcoming specific to any location data provider, it reflects the actual network topology, in the same way mobile CGNAT limits precision for cellular users for a related but distinct reason.
This matters increasingly as satellite internet expands into rural and remote areas that previously had no broadband option at all, since some of the very regions most likely to benefit from satellite connectivity are also the regions where IP-based location will be least precise for exactly this reason. If your application relies on IP geolocation for something like regional content delivery or fraud scoring, and you see unexpectedly coarse or seemingly inconsistent results for a subset of traffic, checking whether that traffic originates from known satellite internet ranges is a useful diagnostic step before assuming a data quality problem elsewhere.
The asn and organization fields are the most direct way to spot this pattern. A satellite internet operator will generally show up clearly in those fields, giving you a reliable signal to treat that traffic's geographic fields with wider tolerance than you would for a typical fixed broadband connection. Our IPv4 and IPv6 lookups return ASN and organization alongside the geographic result specifically so you can make this kind of connection-type-aware judgment rather than treating every IP address as equally precise regardless of the network carrying it.
