About this tool

IP Geolocation Lookup asks the third-party service ip-api.com for the location and network owner of an IPv4 or IPv6 address. The request goes straight from your browser to ip-api.com, so that service sees the address you enter and your own IP address; UtilityKit's server is not involved. Leave the field blank to look up your own address — the page also does this once automatically when it opens. A successful lookup shows country and country code, city, region, ISP, latitude/longitude and the address queried, plus the ZIP code and AS number when a ZIP is returned. At present ip-api.com refuses these requests because its free tier does not serve HTTPS, so the tool shows the message “SSL unavailable for this endpoint” instead of a result. City-level results from any IP geolocation database are approximate.

Why use it

  • One form handles both IPv4 and IPv6 addresses.

  • Leaving the field blank looks up your own public IP and apparent location.

  • Shows the ISP and coordinates next to the country, region and city.

How to use

  1. Enter an IPv4 or IPv6 address, or leave the field blank to look up your own public IP.
  2. Click Lookup or press Enter; the page also runs one lookup of your own IP when it opens.
  3. Read Country, City, Region, ISP, Coordinates and IP Queried in the result cards.
  4. If a ZIP code is returned, a line below the cards shows the ZIP and AS number.
  5. If you see “SSL unavailable for this endpoint”, the provider refused the request and no data is available.

When it helps

  • Verifying where a VPN or proxy connection appears to originate from after configuration.
  • Identifying the country or ISP of suspicious traffic in web server access logs.
  • Checking your own apparent public IP and location.
  • Geolocating IPs in security incident reports.

Examples

Any lookup today

Input
8.8.8.8
Expected result
SSL unavailable for this endpoint, order a key at https://members.ip-api.com/

Blank field

Input
(empty)
Expected result
Looks up your own public IP; today it returns the same “SSL unavailable for this endpoint” message.

Tips

  • City-level accuracy varies — treat the city result as approximate and rely on country/ASN for stronger conclusions.
  • If the ASN points to a hosting provider (DigitalOcean, AWS, OVH), the IP is likely a server, VPN, or scraper — not a residential user.
  • GeoIP databases lag real allocation by 1-4 weeks, so very recently allocated IP ranges may show stale country data.
  • A PTR (reverse DNS) record often reveals more about the operator than geolocation alone; check it with dig -x or nslookup.
  • For fraud detection, check both the IP geolocation and the timezone offset in the user's browser — mismatches are a strong VPN signal.
  • Mobile carrier IPs often geolocate to the carrier's regional hub, not the user's actual location — expect 100+ km error.
  • When auditing logs, group IPs by ASN rather than by city to see infrastructure-level patterns.

Frequently Asked Questions

Who sees the IP addresses I look up?
ip-api.com. Your browser sends the address you enter, and its own IP, directly to that service. The page also sends your own IP automatically when it opens.
Why does it show “SSL unavailable for this endpoint”?
The tool calls ip-api.com over HTTPS, which the provider reserves for paid keys, so free lookups are refused and no location data is returned.
How accurate is IP geolocation?
Country-level accuracy is typically over 95%. City-level accuracy varies — it may be off by tens of kilometers. Coordinates shown are the center of the inferred location area, not a precise address.
Can I look up private IP addresses (192.168.x.x)?
Private and reserved ranges (RFC 1918) have no public geolocation. ip-api.com answers with a failure message such as “private range”, which the tool displays.
Does it reveal someone's home address?
No. IP geolocation resolves to the ISP's network infrastructure, not the subscriber's physical address. The result is typically the ISP's exchange or regional hub.
What is an ASN?
An Autonomous System Number (ASN) identifies a network controlled by a single organization or ISP on the internet. It is used for BGP routing.

Glossary

GeoIP database
A regularly updated mapping of IP address ranges to geographic and network metadata. MaxMind GeoIP2 and IP2Location are the major commercial providers; databases are typically refreshed weekly.
ASN
Autonomous System Number — a unique 16- or 32-bit identifier (e.g. AS15169 for Google) for a network or group of networks under a single administrative routing policy. Used by BGP for inter-network routing.
BGP
Border Gateway Protocol — the routing protocol that connects autonomous systems on the public internet. ASN announcements via BGP determine which network owns which IP range.
IPv4
The original Internet Protocol address format, 32 bits long, written as four dotted decimal octets (e.g. 93.184.216.34). About 4.3 billion total addresses, exhausted in 2011.
IPv6
The successor protocol with 128-bit addresses (e.g. 2606:2800:220:1:248:1893:25c8:1946) providing 3.4×10³⁸ unique addresses, designed to replace IPv4 long-term.
RFC 1918 private ranges
IP ranges reserved for private internal networks: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 — not routable on the public internet and have no geolocation.
Anycast
A network addressing scheme where the same IP is announced from multiple physical locations and BGP routes traffic to the nearest one. Common for DNS resolvers (1.1.1.1, 8.8.8.8) and CDNs.
Regional Internet Registry (RIR)
Organizations that allocate IP address blocks within geographic regions: ARIN (North America), RIPE (Europe), APNIC (Asia-Pacific), LACNIC (Latin America), AFRINIC (Africa).
