API - Translator Text / Speech: Microsoft Translator with IP filtered firewalls

We do NOT RECOMMEND to run Microsoft Translator from behind an IP filtered firewall. The setup is likely to break in the future, without notice.
It is better to use domain-name filtering.

The IP addresses used as of April 12, 2017:

For - Text Translator API

For - Speech Translator API


For (Azure Token Service)

The above doesn’t cover the Microsoft Office built-in translation functionality, which uses a very large set of access points.
