# Bonnard's IP addresses to allow

> The IP addresses Bonnard connects from, and the port to allow them on for each database.

Updated: 2026-10-12

Bonnard connects to your database from fixed IP addresses. If your database limits who can connect, allow them on
its port.

## Addresses

```text
208.77.244.241
208.77.244.242
152.55.184.240
```

In the console at `app.bonnard.ai`, the connect form lists them under **Allow our IP addresses**. The form says they
are stable, and that Bonnard gives notice before changing them.

## Ports

Table: The port to allow for each database

| Database | Port |
| --- | --- |
| [PostgreSQL](https://bonnard.ai/docs/connect-data/postgresql.md#2-allow-bonnards-ip-addresses) | `5432` |
| [Amazon Redshift](https://bonnard.ai/docs/connect-data/redshift.md#2-allow-bonnards-ip-addresses) | `5439` |
| [ClickHouse](https://bonnard.ai/docs/connect-data/clickhouse.md#2-allow-bonnards-ip-addresses) | `8443` (HTTPS) or `8123` (HTTP) |
| [Microsoft SQL Server](https://bonnard.ai/docs/connect-data/sql-server.md#2-allow-bonnards-ip-addresses) | `1433` |
| [MySQL / MariaDB](https://bonnard.ai/docs/connect-data/mysql-mariadb.md#2-allow-bonnards-ip-addresses) | `3306` |

If the database listens on another port, allow that one instead. Bonnard cannot reach databases on a private network.

Bonnard reaches BigQuery, MotherDuck and PostHog through each provider's service, with no database port to open.
