# Cloud Services Static IPs

Umbraco Cloud services access external applications using static outbound IP addresses. This enables you to allowlist Cloud services in IP-based firewalls. This is particularly useful if you wish to control access to your website based on IP addresses.

## Allowlisting IP Addresses

To ensure uninterrupted access and functionality, allowlist the global and regional services IP addresses. Use the regional IP addresses from the region where your website is hosted.

### Global Services

```
4.180.158.192/28
```

### Regional Services

Below are the static outbound IP address ranges for regions:

**Europe**

```
4.180.157.208/28
```

**Australia**

```
4.197.15.208/28
```

**Canada**

```
20.220.219.208/28
```

**United Kingdom**

```
20.68.233.144/28
```

**United States**

```
4.227.135.208/28
```

Ensure that these IP ranges are added to your firewall's allowlist to maintain seamless connectivity with Umbraco Cloud services.
