# Allowlisting Whalesync IP addresses

Allowlist Whalesync's static outbound IP address to grant access to your databases and internal systems.

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.
