Finding location from IoT Device IP address

Finding location from IoT Device IP address

 Finding the precise location of an IoT device based solely on its IP address can be challenging and often inaccurate. IP addresses are assigned to devices by internet service providers (ISPs) and generally provide information about the network or region to which the device is connected, rather than its physical location.



However, there are techniques that can be used to estimate the approximate location of an IP address. Here are a few methods:

1. Geolocation Databases: Some organizations maintain databases that map IP addresses to geographic locations. These databases are compiled using various sources such as user-reported data, ISP information, and publicly available data. By querying these databases, it’s possible to obtain an approximate location associated with an IP address.

2. Wi-Fi Network Mapping: In some cases, the IP address of an IoT device may be associated with a Wi-Fi network. By mapping the known locations of Wi-Fi networks, it’s possible to estimate the location of a device connected to a particular network. This method is typically more accurate in urban areas with denser Wi-Fi coverage.

3. Mobile Network Data: If the IoT device is connected to a mobile network, the IP address can provide information about the location of the mobile network’s serving gateway. However, this location may not correspond directly to the physical location of the IoT device, as mobile networks can cover large areas.

It’s important to note that these methods have limitations and may not always provide precise or reliable results. IP addresses can be dynamically assigned, and devices may connect through proxies or virtual private networks (VPNs), which can affect the accuracy of geolocation estimates.

For applications where accurate location information is crucial, IoT devices often incorporate additional positioning technologies such as GPS or triangulation using cellular tower signals to determine their precise location.

Getting Location by IoT Device IP Address with IoTHook

After finding the IP address of the IoT device, to get the Location information from the IP address https://iothook.com/api/get-ip-to-location-address/ or https://iothook.com/api/get-ip-to-location/ A GET request is sent to -address/. With the GET request, first the IoT device IP address is found, then the location is found and the location address is sent.

When a GET request is sent to IoTHook, first the IP address is found and then the location is found. The location example can be sampled in JSON format as follows. {“location”:”Yunusemre,Manisa,TR”}
