IP info / GeoIP

What it does: tells you where an IP address is and who runs it — rough geographic location, the ISP/organization, and its ASN (the network's ID number). Leave it blank to look up your OWN public address ("what does the internet see me as?").

What you need: an IP address — or nothing, to check your own.

Safe to run: yes — a read-only lookup.

What to expect / reading results: the ISP/ASN and a rough city/country. Handy for sanity-checking your own public IP and ISP, or spotting an unexpected origin (e.g. traffic from a country or provider you didn't expect). Note the location is approximate — IP geolocation places the provider's region, not a street address.
