Important

This feature is applicable for applications running on [Cloud Next](/acquia-cloud-platform) technologies.

If your Cloud Next application must communicate to a remote service, and the service requires inbound connections to come from static and known IP addresses, Acquia can provision Web Elastic IP addresses (Web EIPs) for your application environments.

Without Web EIPs, the IP addresses associated with Cloud Next’s infrastructure are subject to change at any time.

Note

*   Cloud Classic customers who already have [elastic IPs](/acquia-cloud-platform/manage-apps/domains/eip) will receive Web EIPs as part of their Cloud Next upgrade.
*   Cloud Next customers who need Web EIPs added to an environment must [create a Support ticket](/service-offerings/support#contact-acquia-support).
*   Cloud IDEs do not support Web EIPs.

Features of Web EIPs
--------------------

*   **Outbound requests come from dedicated IP addresses**:
    
    Web EIPs are designed for applications that must make external requests to services that require allowlisted-inbound connections.
    
*   **No application changes are needed**:
    
    When making requests to external services, Web EIPs are automatically utilized.
    
*   **Dedicated IP addresses through autoscaling and periods of high traffic or elevated resource consumption**:
    
    Web EIPs that are assigned to the application environment persist even after your application scales, eliminating the need to edit IP allowlists before extra capacity can be used at Acquia.
    

Limitations
-----------

*   **PHP scripts and third-party libraries are not supported**:
    
    Acquia does not support custom integrations.
    

Viewing your Web EIPs in the Cloud Platform user interface
----------------------------------------------------------

To view your Web EIPs:

1.  [Sign in to the Cloud Platform user interface](/acquia-cloud-platform/accessing-cloud-platform-user-interface "Accessing the Cloud Platform user interface") and select your application and environment.
2.  In the navigation pane, click **Infrastructure**.
    
    The Infrastructure page displays the Web EIPs for the application environment:

Web EIP compatibility
---------------------

Web EIPs are compatible with the APIs provided by Drupal core for making requests to external services, such as:

*   `drupal_http_request()` in Drupal 7
*   `Drupal::httpClient` in the [current Drupal version](/service-offerings/guide/software-life-cycle#supported-drupal-version)

Additional supported protocols and libraries include:

*   `file_get_contents()` and PHP streams
*   `curl` command line utility and PHP library
*   `wget` command line utility
*   Log forwarding
*   SMTP
*   LDAP
*   SSH/SFTP
*   MySQL
*   Node.js http or https core modules, and http client libraries such as axios, node-fetch, and fetch API
*   Node.js WebSocket clients such as ws and socket.io-client
