How IP Geolocation Works
Dikemas kini 6 minit bacaanoleh pasukan editorial IP Checker
A short technical overview of how IP addresses are mapped to physical locations, and why it is fundamentally probabilistic.
IP geolocation services combine multiple data sources to estimate the location of an IP: registration data from regional internet registries, routing observations, ISP feedback, and active probing.
Data sources
- Regional Internet Registries (RIRs) — ARIN, RIPE, APNIC, AFRINIC, LACNIC.
- BGP routing tables to infer paths and likely points of presence.
- Latency measurements between known landmarks.
- Self-reported data from ISPs and content providers.
Why it is not exact
No technique can reliably bind an IP to a precise GPS coordinate. The internet was simply not designed that way. Treat geolocation as a hint at the country and metro level.
Soalan Lazim
Can geolocation tell which house an IP belongs to?
No. Reputable providers explicitly limit precision to city level.
