+# Static Outbound IP Addresses for Umbraco Cloud
+
+Umbraco Cloud services access external applications with static outbound IP addresses. This enables you to whitelist cloud services in IP based firewalls. This is particularly useful if you wish to control access to your website based on IP addresses.
+
+## Whitelisting IP Addresses
+
+To ensure uninterrupted access and functionality, you should whitelist both the global services IP addresses and the IP addresses specific to 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 various 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 whitelist to maintain seamless connectivity with Umbraco Cloud services.
