# Allowlisting Whalesync IP addresses

In some cases, access to your databases or internal systems from Whalesync may be blocked by your organization's network security settings. Whalesync uses a static outbound IP address for syncing data with your connected databases and services, and for [sync webhook](/features/additional-features/sync-webhooks.md) deliveries.

We recommend that your organization allows the following IP address:

```
34.66.3.22
```

## How to allowlist

### Cloud-hosted databases (AWS, GCP, etc.)

Add `34.66.3.22/32` to the inbound rules of the security group or firewall associated with your database instance.

### Supabase

In your Supabase dashboard, navigate to **Database Settings > Network Restrictions** and add `34.66.3.22/32` as an allowed address.

### Self-hosted / on-premise

Add `34.66.3.22` to your firewall's allowlist for the port your database is running on.
