External APIs, firewalls, or payment gateways often require the IP addresses of your site's outbound server to be added to an allowlist (whitelist).
You can retrieve your site's IPv4 and IPv6 addresses directly from the command line using the srv system metadata command, or request the list from our support team.
Checking Addresses with srv system metadata
Connect to your site via SSH.
Run the following command:
srv system metadata
The command outputs the metadata for your site's server environment:
srv system metadata
Host:
95.217.75.239
2a01:4f9:4a:1b50::2
Cluster:
95.217.75.239
2a01:4f9:4a:1b50::2
95.217.107.11
2a01:4f9:4a:28a8::2

What Do the Different Address Groups Mean?
Field | Meaning and Purpose |
| The host server where your site's container is currently running. Outbound connections from your site (such as PHP or cURL requests) primarily originate from these addresses. |
| All servers within the same server cluster. During maintenance or load balancing, your site's container may move between servers, meaning outbound traffic can originate from any address in the cluster. |
| The addresses of the inbound routing servers (HTTP proxies) to which your domain's A and AAAA DNS records point. |
Add all IPv4 and IPv6 addresses listed under both Host and Cluster to the external service's allowlist. Adding only the DNS addresses (or addresses queried with dig) is not sufficient, as outbound requests from your site do not route through them.
Note on Address Changes:
The IPv4 and IPv6 addresses of a server cluster may change during hardware maintenance and system updates, so you should review the list periodically. In Seravo's cluster architecture, dedicated static IP addresses are not available for sites—see the article Fixed IP Address for more details.

Adding both the Host and Cluster addresses to your allowlist ensures your site's external API integrations continue working reliably even during server maintenance. If you need assistance retrieving your site's addresses, contact us at [email protected].
