Input Information

IP Address Lookup

Look up your current public IP address and related information.

Notes

  • This tool shows public IP addresses.
  • When using a VPN, the VPN server's IP is displayed.
  • IP information is approximate location provided by the ISP.
  • Exact location may not be displayed.

Result

Please look up IP information.

IP Address Lookup A tool that displays your device's public IP address and related geographic information in real-time. An IP address is a unique identifier assigned by your ISP (Internet Service Provider).

Useful for remote access setup, firewall allowlist registration, network troubleshooting, and checking region-restricted content access. Also used for security audits to verify your public IP.

Useful for network administrators and security personnel as a basic diagnostic tool, and for general users to verify connection information.

This tool sequentially calls external APIs (ipinfo.io, ipify) to retrieve information. Displayed locations are based on IP assignment and may differ from actual physical location.

Term Glossary

Public IP Address
A unique address identifying your device on the internet, assigned by your ISP. Used for external access, unlike private IP used within home or office networks.
ISP (Internet Service Provider)
Telecom companies like KT, SK Broadband, LG U+ that provide internet lines. They assign public IPs to users.
VPN (Virtual Private Network)
A technology that encrypts communications and routes them through different servers. When using a VPN, the VPN server's IP is displayed instead of your actual IP.
IP-based Geolocation
A method that estimates approximate city/region using IP assignment information. Cannot determine exact physical address.

  1. Enter an IP address or use auto-detect to check your current public IP.
  2. Click the lookup button.
  3. View the geolocation, ISP, and organization information.

8.8.8.8

A well-known public DNS server operated by Google. It is located in the United States (US).

1.1.1.1

Cloudflare's public DNS server. It is located in Australia.

Auto-Detect

Click lookup to see your current network's public IP along with its approximate location and ISP information.

Lookup Method

Identifies the access IP through external APIs and retrieves geographic information. Two APIs are tried sequentially.

Primary: ipinfo.io

GET https://ipinfo.io/json?token=demo

Provides IP, city, region, country, coordinates, ISP, timezone, and more.

Fallback: ipify

GET https://api.ipify.org?format=json

When the primary fails, retrieves minimum IP information to display.

VPN Usage

  • Use a VPN service to hide your IP.
  • Connected VPN changes the displayed IP.

Privacy

  • Public IP can expose approximate location.
  • Router external IP is also visible in admin pages.

Remote Access Setup

  • Register your IP in firewall allowlists.
  • If not static, update regularly.

Network Troubleshooting

  • Check your IP and ISP first when connection issues occur.
  • Consider restarting the router if results differ from expectations.

Region Restriction Check

  • Content access is determined based on IP.
  • Note that country information is based on ISP assignment.

Security Audit

  • Trace suspicious connections by IP.
  • Compare with the IP in login notifications.

QWhat information does an IP lookup provide?

It provides the public IP address, approximate city/region/country location, coordinates, timezone, postal code, and ISP (Internet Service Provider) and organization information.

QWhat is the difference between IPv4 and IPv6?

IPv4 is a 32-bit address such as 192.168.1.1, while IPv6 is a 128-bit address such as 2001:0db8:85a3::8a2e:0370:7334. IPv6 offers a vastly larger address space.

QHow accurate is the geolocation?

IP-based location is usually an approximation at the city level and accurate at the country level, but not at the street or building level. Accuracy varies by ISP data.

QIs it safe to look up my own IP?

Yes. Lookups use public databases and are not stored, so it is safe. Still, since an IP reveals approximate location, be careful about sharing it.

QCan it detect VPNs or proxies?

It is possible to tell whether a VPN or proxy is in use from the IP. When using a VPN, the location and ISP often show the VPN provider instead.
