IP Addresses

IP Addresses are the way compters are addressed on the Internet. IP Addresses typically come up in conversation about Files.com in the conversation of a firewall or client configuration.

Whitelisting Files.com IP Addresses in Your Firewall

Files.com is a large global cloud application. Enough of our customers are in environments that require whitelitsed IP addresses, so we commit to publishing a list of IP addresses that may be involved in inbound or outbound connections to Files.com.

The list is quite long because it includes IPs in all 7 regions where we operate servers, as well as IPs for different service types such as API, FTP, SFTP, WebDAV, and integration endpoints that are specifically used in relation to our various integrations.

Unfortunately, are not able to split this list into sub-lists by region or by integration type.

This list may change. To keep up to date with the latest list, please regularly poll our IP Address List API.

IP List

Please make sure that all IP addresses are white-listed, as we may switch between these at any time.


If you restrict inbound or outbound access via a firewall, you may also need to determine which ports to whitelist in conjunction with our IP list. Ports are protocol specific.

For API traffic, which is used by our Desktop app, mobile apps, web app, CLI, SDKs, and API, port 443 (HTTPS) should be whitelisted.

If you are using FTP, you will need to whitelist port 21 and FTP data ports 40000-50000, and optionally our three alternate FTP ports 990, 3021, and 3990 if they apply to your use case.

If you are using SFTP, you will need to whitelist port 22 and optionally our alternate SFTP port 3022 if it applies to your use case.

Use of IP List for Outbound Connections from File.com

For Outbound Connections from Files.com, Files.com will use IPs from the above list for most types of outbound connections, including Webhooks, SMTP, LDAP, and Remote Server connections via FTP and SFTP.

For other Remote Server types, including WebDAV, S3, Azure, GCP and others, we do not currently use IPs from this list. We understand that this capability is important to many customers and we are working internally on the ability to support this this the near term.

Accessing Files.com or My Site via a Hardcoded or Static IP Address

We do not support or recommend that any of our customers ever hardcode IP addresses directly into their client application.

We use DNS as part of our redundancy and disaster recovery strategy and we expect that our customers will always use DNS to look up [subdomain].files.com or app.files.com as appropriate.

We also use Geo-DNS to route traffic to the fastest and closest available server, as well as to take troubled servers out of the active pool.

Using a hardcoded or stale IP may well direct you to a server that is down, currently undergoing maintenance, etc.

Dedicated IP Addresses

Customers often ask for Dedicated IP addresses as a way to avoid having to whitelist a huge list of IP addresses for firewall purposes.

Files.com automatically provisions a pair of dedicated IP addresses for every site that has a custom domain enabled. We do that because FTP, unlike HTTP, requires that every custom domain be hosted on a dedicated IP address in order to have a custom SSL Certificate that matches the domain.

This means that if you have users who restrict outbound access via a firewall, they will only need to whitelist your two dedicated IP addresses. rather than having to whitelist our entire published list of IP addresses (see above).

Custom domains and, therefore, dedicated IPs are only available on the Power and Premier plans. If you are on a Starter plan, you will need to upgrade to use a custom domain or dedicated IPs.

Dedicated IPs, once provisioned, are used for both inbound connections to your site via your custom domain, as well as outbound connections from Files.com to certain applicable Remote Servers that are used for Remote Server Sync and Remote Server Mount.

Dedicated IP Addresses For Outbound Connections from File.com

By default, Files.com will use your dedicated IP addresses for outbound connections to FTP, SFTP, WebDAV, and S3 Compatible remote servers.

This applies to our Remote Server Sync and Remote Server Mount feature.

However, you can disable the use of your dedicated IP in these circumstances if you need to. (You might do that if your counterparty has already whitelisted the main Files.com IP range, for example.)

You may also optionally opt-in to having your Dedicated IP Address be used for outbound connections to Azure. We are open to considering allowing outbound Dedicated IP Addresses to work for other integrations if there is a demonstrated need. Please let us know if you require this capability on another remote server type.

We will not use your dedicated IP addresses for other types of outbound connections such as webhooks, LDAP, or SMTP, and our view is that this likely isn't a priority for most customers. If you have a need to have webhooks, LDAP, or SMTP originate from a dedicated IP address, we'd love to learn more about your exact use case.

How to get dedicated IPs

In order to receive dedicated IP addresses for your site, you will first need to set up a custom domain. View instructions for setting up a domain..

Once your custom domain is set up and active, you can find your two dedicated IP addresses listed at the bottom of the page at Settings > Integrations > View firewall configuration information.

Static IP Addresses

Dedicated IP addresses are exclusive to your Files.com site and act as static IP addresses.

It is our goal to have your Dedicated IPs remain the same, and we work hard to avoid having IP Addresses change out from under you. In practice, dedicated IPs for our customers have remained the same for the past several years.

If we ever have to make changes to your IP addresses, we will endeavor to provide advance notice.

For extra capabilities, we have implemented an automated mechanic for you to be able to get real time notifications when a change occurs. You can achieve this by polling the /ip_addresses API endpoint shown in our API documentation. This endpoint returns a response including both our published list of IP addresses, and your site's two dedicated IP addresses.

Deactivating a Custom Domain

If you remove a custom domain from your site, the dedicated IPs associated with that custom domain are removed from active use and are no longer associated with your site.

Your users are still able to connect using your subdomain.files.com address as the host, but are no longer able to connect via your custom domain, and your subdomain will no longer resolve to the two IP addresses that were dedicated to your site.

When connecting after your custom domain is deactivated, your subdomain will resolve to an IP address from the general pool shown in your web interface at Settings > Integrations > Firewall Configuration Information. Those users who require whitelisting in their local network firewalls or elsewhere will need to cover that entire list to ensure that they have consistent connection results.
