Hello @Abhi Tripathi , and welcome to Microsoft Q&A.
While you can download the IP ranges from here, please be aware that the IP ranges may be subject to change. In light of this, you may wish to consider using one of the programmatic methods of retrieval (found on the same linked page).
Also, please be aware that Data Flows does not fall under the Data Factory IP ranges. Data Flows does not support fixed IP ranges.
If you download the list, simply do a search for DataFactory.WestUS2
.
Please let me know if this helps, or if you have any questions.
Thank you
Martin
