How to Prevent Viewing Internal IP Addresses

Last updated January 14, 2024 by Appdome

Learn to Prevent Viewing internal IP addresses in Mobile apps, in mobile CI/CD with a Data-Driven DevSecOps™ build system.

What is IP Address Visibility?

IP address visibility is important when you are auditing the IP addresses your application uses. Auditing IP addresses is useful in several cases. For example, large companies with subsidiaries and partnerships, may use auditing to scan your IP address ranges with the purpose of identifying which ranges belong to a core business, subsidiaries, or joint ventures.

When Should I Enable IP Address Visibility?

When an application establishes a connection Appdome may generate an internal IP address for the app and then translate the IP address back to the actual address when traffic leaves the app (a form of Network Address Translation or NAT). Building an app with Appdome IP address visibility into the app ensures that the actual IP address of the destinations are reported to the app.

Prerequisites for Using IP Address Visibility:

To use Appdome’s mobile app security build system to Prevent Viewing internal IP addresses , you’ll need:

Prevent Viewing internal IP addresses on Mobile apps using Appdome

On Appdome, follow these 3 simple steps to create self-defending Mobile Apps that Prevent Viewing internal IP addresses without an SDK or gateway:

  1. Upload the Mobile App to Appdome.

    1. Upload an app to Appdome’s Mobile App Security Build System

    2. Upload Method: Appdome Console or DEV-API
    3. Mobile App Formats: .ipa for iOS, or .apk or .aab for Android
    4. IP Address Visibility Compatible With: Obj-C, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more
  2. Build the feature: IP Address Visibility.

    1. Building IP Address Visibility by using Appdome’s DEV-API:

      1. Create and name the Fusion Set (security template) that will contain the IP Address Visibility feature as shown below:
      2. fusion set that contains IP Address Visibility

        Figure 1: Fusion Set that will contain the IP Address Visibility feature
        Note: Naming the Fusion Set to correspond to the protection(s) selected is for illustration purposes only (not required).

      3. Follow the steps in Sections 2.2.1-2.2.2 of this article, Building the IP Address Visibility feature via Appdome Console, to add the IP Address Visibility feature to this Fusion Set.

      4. Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set. Copy the Fusion Set ID from the Fusion Set Detail Summary (as shown below): fusion Set Detail Summary image

        Figure 2: Fusion Set Detail Summary
        Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).

      5. Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, App Center, Jenkins, Travis, Team City, Circle CI or other system:
        1. Build an API for the app – for instructions, see the tasks under Appdome API Reference Guide
        2. Look for sample APIs in Appdome’s GitHub Repository
    2. Building the IP Address Visibility feature via Appdome Console

      To build the IP Address Visibility protection by using Appdome Console, follow the instructions below.

      1. Where: Inside the Appdome Console, go to Build > Security Tab > Secure Communication section.
      2. How: Check whether is toggled On (enabled), otherwise enable it . The feature IP Address Visibility is enabled by default, as shown below. Toggle (turn ON) IP Address Visibility, as shown below.
        If needed, Customize the Threat Notification to be displayed to the mobile end-user in a standard OS dialog notification when Appdome Prevents Viewing internal IP addresses.
        IP Address Visibility option

        Figure 3: Prevent Viewing internal IP addresses option
        Note: The App Compromise Notification contains an easy to follow default remediation path for the mobile app end user. You can customize this message as required to achieve brand specific support, workflow or other messaging.

      3. When you select the IP Address Visibility you'll notice that your Fusion Set you created in step 2.1.1 now bears the icon of the protection category that contains IP Address Visibility

        Fusion Set applied IP Address Visibility

        Figure 4: Fusion Set that displays the newly added IP Address Visibility protection

      4. Click Build My App at the bottom of the Build Workflow (shown in Figure 3).
    Congratulations!  The IP Address Visibility protection is now added to the mobile app
  3. Certify the IP Address Visibility feature in Mobile Apps

    After building IP Address Visibility, Appdome generates a Certified Secure™ certificate to guarantee that the IP Address Visibility protection has been added and is protecting the app. To verify that the IP Address Visibility protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below: IP Address Visibility shown in Certificate secure

    Figure 5: Certified Secure™ certificate

    Each Certified Secure™ certificate provides DevOps and DevSecOps organizations the entire workflow summary, audit trail of each build, and proof of protection that IP Address Visibility has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that IP Address Visibility and other mobile app security features are in each build of the mobile app

Using Threat-Events™ for Viewing internal IP addresses Intelligence and Control in Mobile Apps

Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when Viewing internal IP addresses is detected. To consume and use Threat-Events™ for Viewing internal IP addresses in Mobile Apps, use AddObserverForName in Notification Center, and the code samples for Threat-Events™ for Viewing internal IP addresses shown below.

The specifications and options for Threat-Events™ for Viewing internal IP addresses are:

Threat-Event™ Elements Prevent Viewing internal IP addresses Method Detail
Appdome Feature Name IP Address Visibility
Threat-Event Mode
OFF, IN-APP DEFENSE Appdome detects, defends and notifies user (standard OS dialog) using customizable messaging.
ON, IN-APP DETECTION Appdome detects the attack or threat and passes the event in a standard format to the app for processing (app chooses how and when to enforce).
ON, IN-APP DEFENSE Uses Appdome Enforce mode for any attack or threat and passes the event in a standard format to the app for processing (gather intel on attacks and threats without losing any protection).

With Threat-Events™ enabled (turned ON), Mobile developers can get detailed attack intelligence and granular defense control in Mobile applications and create amazing user experiences for all mobile end users when Viewing internal IP addresses is detected.


The following is a code sample for native Mobile apps, which uses all values in the specification above for IP Address Visibility:


Important! Replace all placeholder instances of <Context Key> with the specific name of your threat event context key across all language examples. This is crucial to ensure your code functions correctly with the intended event data. For example, The <Context Key> could be the message, externalID, OS Version, reason code, etc.



Using Appdome, there are no development or coding prerequisites to build secured Mobile Apps by using IP Address Visibility. There is no SDK and no library to code or implement in the app and no gateway to deploy in your network. All protections are built into each app and the resulting app is self-defending and self-protecting.

Releasing and Publishing Mobile Apps with IP Address Visibility

After successfully securing your app by using Appdome, there are several available options to complete your project, depending on your app lifecycle or workflow. These include:
