SharePoint Online URLs and IP Addresses

IT Administrators may want to control communication to specific SharePoint Online sites for enterprises or professionals and small businesses through an on-premises firewall. Knowing IP address ranges used by SharePoint Online will allow this.

Outgoing IP Address Ranges

Ports in your on-premises firewall may need to be opened to accept network traffic originating from Microsoft Datacenter IP addresses. For the most part, SharePoint Online works through the browser using the HTTP or HTTPs protocols over ports 80 and 443, with some outbound traffic on port 25 (SMTP). The IP address ranges used by SharePoint Online are listed below. Note that because Project Online is a SharePoint Online service, these IP address ranges also apply to Project Online:

 Note    If you see issues after successfully setting up firewall ports, please check for updates to the IP values in this article.
