Hello Hao Yuan,
The IP addresses that you reference are accurate for the 10ay instance of Tableau Online. The first two entries were recently added, and you can find more detail on those IP addresses here:
However, any requests originating from Tableau Online today should be within the 188.8.131.52/24 range. If you receive an error connecting to your Azure SQL database despite the request originating from that range of addresses, I recommend that you create a case with our Support team for deeper troubleshooting:
Hope this helps!
