How the Tool Identifies Your Connection
The "What Is My IP" tool instantly displays the public IP address a user's current internet connection is using to access the web. When the page loads, the tool automatically reads the connection parameters directly from the incoming request headers at the network edge. It identifies whether the connection is utilizing an IPv4 or IPv6 protocol and provides real-time technical details about the network provider, the estimated geographical location of the connection, and the specific edge node serving the request.
The tool does not require the user to type or upload any data. If you need to refresh the connection details, you can interact with the manual trigger labeled "Check again". While loading, the interface displays Reading your connection…. Once the connection is read, it shows the exact time of the measurement as Checked at ….
The tool displays only one public IP address at a time—specifically the one the connection actually used to load the page (either IPv4 or IPv6). It does not display both simultaneously. If a connection cannot be read due to network issues, the tool displays the error message: Could not read your connection. Check your network and try again.. If you attempt to copy the IP address using an interface shortcut and it fails, the tool displays: Copy failed. Select the address and copy it manually.. If a specific data field cannot be retrieved from the connection or routing database, the interface displays Not available.
Understanding the Connection and Network Outputs
The tool organizes its outputs into distinct sections to help users verify their active public network identity, troubleshoot connectivity issues, or confirm if a VPN or proxy is successfully masking their actual location.
The interface applies specific badges to distinguish between different types of data:
- Observed: Applied to direct connection measurements.
- Estimated: Applied to IP-derived routing and location data.
Under the main IP display, labeled Your public IP address, the tool presents three primary data sections:
This connection
The values under this heading are directly measured from the active session:
- HTTP protocol: The protocol version used for the connection.
- TLS version: The active Transport Layer Security version.
- Edge node: The specific edge server/colo handling the request.
- Round-trip time: The measured network latency (RTT).
Network
This section displays routing details associated with your internet service provider:
- ASN: The Autonomous System Number.
- Network organization: The organization or ISP operating the network.
Location
These geographical values are estimated from IP routing registries:
- Country: The country registered to the IP.
- Region: The estimated state or region.
- City: The estimated city.
- Postal code: The estimated postal code.
- Coordinates: The estimated latitude and longitude.
- Time zone: The time zone of the IP location.
- Local time there: The current local time in the estimated time zone.
Technical Differences Between IPv4 and IPv6
Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) are the two coexisting standards used to route data across the global internet. IPv4 addresses use a 32-bit format, which limits the total pool to approximately 4.3 billion unique addresses. Due to the rapid expansion of connected devices, this pool has been depleted, prompting the industry transition to IPv6. IPv6 addresses use a 128-bit format, providing an virtually inexhaustible number of unique addresses.
Many modern networks operate as dual-stack networks, meaning they support both protocols simultaneously. When a device connects to a website, the operating system and the network negotiate which protocol to use. The "What Is My IP" tool displays the specific protocol that was actively selected and used to establish the current session.
Public vs. Private IP Addresses
A public IP address is the unique identifier assigned to your internet connection by your Internet Service Provider (ISP). This address is visible to every website and server you interact with on the public internet.
In contrast, private IP addresses (such as those starting with 192.168.x.x) are used exclusively within local area networks, such as your home or office. Local routers use Network Address Translation (NAT) to map multiple private devices to a single public IP address assigned by the ISP. This allows multiple local devices to share one public connection. The "What Is My IP" tool completely ignores private local IP addresses, as they do not route over the public internet and are not visible to external web servers.
IP Geolocation and Routing Mechanics
IP geolocation databases map IP address blocks to specific geographic locations. These databases rely on registration data from Regional Internet Registries (RIRs) and network routing paths. Because IP addresses are registered to networks rather than physical buildings, these location estimates point to network distribution hubs or ISP routing centers rather than precise street addresses.
When a user connects to the internet through a Virtual Private Network (VPN), proxy, or relay, the path of the data is altered. The user's traffic is routed through an encrypted tunnel to an intermediary server. As a result, the "What Is My IP" tool will display the IP address, network organization, and location of the VPN or relay server rather than the user's actual home or office network.
Autonomous System Numbers (ASNs) Explained
An Autonomous System (AS) is a collection of connected Internet Protocol routing prefixes under the control of one or more network operators on behalf of a single administrative entity, such as an ISP, a large corporation, or a university. Each Autonomous System is assigned a unique Autonomous System Number (ASN), which is a globally unique identifier used in routing protocols. ASNs allow different networks to exchange routing information and direct traffic across the global internet. The ASN displayed by the tool identifies the specific network organization responsible for routing your connection's traffic.
Privacy and Data Processing
All processing happens instantly at the network edge during the active connection. The tool reads the IP address directly from the incoming request headers. The IP address and connection details are used solely to display them back to the user; they are never stored, logged, or shared.
Frequently Asked Questions
Is this my public or private IP address?
Public. It is the address your internet provider assigns to your connection, and the one every website you visit can see. Devices also hold private addresses such as 192.168.x.x that only work inside your home or office network and never appear here.
Why is the location not exactly where I am?
The location is estimated from your IP address, which is registered to a network rather than a building. It is usually right at the country or region level, but it can point at your provider’s routing hub instead of your city — and when you use a VPN or relay, it shows that server’s location.
Why do I see an IPv6 address instead of IPv4?
A connection uses one protocol at a time, and on many modern networks that is IPv6. Both are your public address; this page shows the one this connection actually used, so the answer can differ between networks or devices.
Why did my IP address change?
Most home and mobile connections use dynamic addressing: your provider can assign a new address when the router reconnects, when you switch between Wi-Fi and mobile data, or on its own schedule. Check again to read the current one.
