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 api.microsofttranslator.com - Text Translator API
65.55.108.5
65.55.252.36
111.221.29.48
207.46.194.62

For dev.microsofttranslator.com - Speech Translator API
65.55.252.57
131.253.14.213
111.221.29.208
207.46.194.29


For hub.microsofttranslator.com
65.52.200.100

For api.cognitive.microsoft.com (Azure Token Service)
104.42.239.93
52.179.13.227
52.175.35.166
52.230.30.206
52.174.60.141

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