Frequently Asked Questions

#### What IP address does Stockeo use for FTP connections? <a href="#what-ip-address-does-fulfilleo-use-for-ftp-connections" id="what-ip-address-does-fulfilleo-use-for-ftp-connections"></a>

Stockeo connects to FTP servers from the IP address **138.197.226.212**. If your supplier's server is protected by a firewall, ask them to whitelist this address so that incoming connections from it are allowed.

This usually indicates one of two things: either the metafield is already selected in another automation, or its type is not supported by Stockeo.

For more details, please refer to the [**Supported metafield types**](/data-mapping/metafields.md) section.
