IP Address Lookup

An IP (Internet Protocol) address is a unique numerical identifier assigned to every device connected to the internet. It serves two primary purposes: host or network interface identification and location addressing. Every time you visit a website, send an email, or stream a video, your IP address is used to route data between your device and the destination server.

What Is My IP Address?

Your public IP address is the address that websites and online services see when you connect to them. It is assigned by your Internet Service Provider (ISP) and can reveal your approximate geographic location, the ISP you use, and whether you are using a residential or commercial connection. This tool automatically detects your public IP by making a request to a geolocation API, which reads the source IP of your request. No personal data is stored or logged by SecureBin.

IPv4 vs IPv6

IPv4 addresses use a 32-bit format written as four decimal numbers separated by dots (e.g., 192.168.1.1), providing roughly 4.3 billion unique addresses. Due to the explosive growth of internet-connected devices, IPv4 addresses have been exhausted globally. IPv6 was developed to solve this shortage, using a 128-bit format written as eight groups of hexadecimal digits separated by colons (e.g., 2001:0db8:85a3::8a2e:0370:7334). IPv6 supports approximately 340 undecillion addresses, ensuring the internet can continue to grow. This tool automatically detects whether an IP is v4 or v6 based on its format.

IP Geolocation

IP geolocation maps an IP address to a physical location. While it cannot pinpoint an exact street address, it typically provides accurate city-level and region-level data. Geolocation databases are maintained by organizations like MaxMind, IP2Location, and ipapi, which correlate IP ranges with geographic data from ISP registrations, routing tables, and other public sources. Common use cases include content localization, fraud detection, regulatory compliance, targeted advertising, and access control.

ISP and ASN Information

Every IP address is part of a block allocated to an ISP or organization. The ISP field shows which company provides internet connectivity for that IP. The ASN (Autonomous System Number) identifies the network operator in the global routing table. ASNs are assigned by Regional Internet Registries (RIRs) such as ARIN, RIPE NCC, and APNIC. Knowing the ASN can help network engineers trace routing issues, identify hosting providers, and understand network topology.

Privacy and VPN Detection

If you are using a VPN, proxy, or Tor, this tool will show the IP address of the exit node rather than your real IP. This is by design, as VPNs mask your true IP to protect your privacy. Organizations use IP intelligence to detect VPN and proxy usage for fraud prevention, but for individual users, VPNs remain an important tool for maintaining online privacy and security.

How This Tool Works

This IP lookup tool runs entirely in your browser. When you click "Detect My IP" or enter an IP address, a request is made directly from your browser to the ipapi.co public API, which returns geolocation data in JSON format. No data passes through SecureBin servers. The API provides city, region, country, postal code, timezone, ISP, ASN, and geographic coordinates. The map view uses an OpenStreetMap embed to visualize the approximate location.

Common Use Cases

Developers use IP lookups to debug network issues, verify CDN routing, test geo-targeting logic, and validate firewall rules. System administrators use them to trace suspicious traffic, verify VPN connections, and audit access logs. Security professionals use IP intelligence for threat analysis and incident response. Everyday users check their IP to verify their VPN is working or to understand what information websites can see about their connection.
