IP Address Lookup

Detect your public IP instantly or look up any IPv4/IPv6 address or hostname for ISP, ASN, IP version, and approximate city/country/timezone metadata from public IP databases. Dual-stack connections may show both IPv6 and IPv4. Private, loopback, and local network addresses cannot be geolocated — the tool explains why instead of returning misleading results. For legitimate network troubleshooting and education only; not a surveillance or stalking tool.

How to Use the IP Address Lookup

Detect your public IP or enter an IPv4/IPv6 address or hostname to view ISP, ASN, version, and approximate location from public databases.

  1. Open IP Address Lookup.
  2. Leave the field blank and click Detect my IP to see your public address as seen from the internet.
  3. Or enter an IPv4/IPv6 literal (e.g. 8.8.8.8) or hostname and click Lookup.
  4. Review IP version, ISP/org, ASN, country, approximate city/region, and timezone in the result cards.
  5. If dual-stack applies, note any alternate IPv4 or IPv6 address listed below the primary result.
  6. Use the readings for legitimate network debugging — not to pinpoint private individuals.

Public vs private addresses

  • Public IPs — routable on the internet; ISP and approximate geo may be shown.
  • Private/local IPs (10.x, 192.168.x, 127.x, link-local IPv6) — rejected with a clear explanation.
  • Hostname lookups resolve DNS first, then geolocate the resulting public IP.

Data limits

Geolocation is approximate network geography from public WHOIS/GeoIP databases — not GPS and not proof of physical presence. Accuracy varies by provider and address type (mobile, datacenter, VPN).

Privacy and acceptable use

Use this tool for troubleshooting your connection, verifying server egress IPs, or learning how public IP metadata works. Do not use it for stalking, harassment, or unauthorized monitoring of others.

Limitations

VPNs, carrier-grade NAT, and corporate proxies change what address you see. The tool cannot deanonymize users or bypass privacy protections.

FAQ

How do I find my public IP address?

Leave the input blank and click Detect my IP. The tool queries public IP services and shows the address as seen from the internet, plus ISP and approximate location when available.

Can I look up someone else's IP?

You can look up public IP addresses or hostnames you legitimately need to troubleshoot (your server, API endpoint, etc.). Do not use this tool to track or harass individuals — location data is approximate ISP/network geography, not a home address.

Why can't I geolocate 192.168.x.x or 127.0.0.1?

Private RFC1918, link-local, and loopback addresses are not routable on the public internet. Public geolocation databases have no meaningful location for them.

How accurate is the location?

City and region are estimates from third-party IP databases — often correct at metro or ISP level, sometimes wrong. They do not reveal exact street addresses or GPS coordinates of a person.

Why do I see IPv6 instead of IPv4?

When your network prefers IPv6, detection returns your IPv6 public address first. Some lookups also show an alternate IPv4 when dual-stack detection succeeds.

What are ISP and ASN fields?

ISP (or organization) names the network provider. ASN (Autonomous System Number) identifies the network operator registered for that IP range — useful for routing and abuse contacts.

Can I look up a hostname?

Yes. Enter a domain or hostname and the tool resolves it to a public IP, then returns network metadata for that address.

Is my lookup history stored?

Lookups run from your browser to public providers. ToolsLibrary does not build a surveillance profile of queried IPs; follow normal browser and shared-device hygiene.

Which data provider is used?

Public IP detection and geolocation use third-party services such as ipwho.is and ipify over HTTPS. Results reflect their databases, not live GPS.

Is this a VPN or security audit?

No. It displays public registration metadata only. It cannot confirm whether an IP belongs to a specific person, bypass privacy tools, or certify network security.
