IPv6 support in Office 365 services

 

Topic Last Modified: 2014-09-08

Summary: Describes IPv6 support in Microsoft Office 365 components and in Office 365 government offerings.

If you started your Office 365 subscription service in 2013 or later, your services support IPv6. You don’t have to use IPv6, but we recommend it. If you want to control communications to Office 365, use the IP address ranges in Office 365 IPv6.

If you’re upgrading to 2013 and your ISP offers IPv6, the Exchange Online service is upgraded to enable IPv6 automatically. Contact your ISP to ensure this transition goes smoothly. Early coordination with your ISP will avoid difficulties later.

If the program that you use to connect to Exchange Online supports IPv6, it will use IPv6 by default on both wired and wireless networks. If you want to control communications to Exchange Online, use the IP address ranges in Exchange Online URLs and IP Address Ranges.

Office 365 Government G1/G3/G4/K1   If the program that you use to connect to SharePoint Online supports IPv6, it will attempt to use IPv6 by default.

Public multi-tenant cloud   Microsoft enables SharePoint Online IPv6 at your request. After IPv6 is enabled, if the program that you use to connect to SharePoint Online supports IPv6, it uses IPv6 by default.

If the program that you use to connect to SharePoint Online supports IPv6, it will use IPv6 by default on both wired and wireless networks. If you want to control communications to SharePoint Online, use the IP address ranges in SharePoint Online URLs and IP Addresses.

Office 365 Government G1/G3/G4/K1   If the program that you use to connect to SharePoint Online supports IPv6, it will attempt to use IPv6 by default.

Microsoft will enable IPv6 for Lync Online at your request in the public multi-tenant cloud and in Office 365 Government G1/G3/G4/K1 subscriptions. After it’s enabled, if the program that you use to connect to Lync Online supports IPv6, it will use IPv6 by default. If you want to control communications to Lync Online, use the IP address ranges in Lync Online URLs and IP Addresses.

Exchange Online Protection (EOP) supports IPv6 if the transmission occurs over Transport Layer Security Protocol. EOP was previously named Forefront Online Protection for Exchange (FOPE). FOPE does not support IPv6. If you want to control communication to FOPE, use the IP address ranges in Forefront Online Protection for Exchange Online IP Addresses. For the EOP range, use Exchange Online Protection IP Addresses.

Office 365 IPv6 support for government offerings conforms to the Office of Management and Budget (OMB) Memorandum for Chief Information Officers of Executive Departments and Agencies, as well as the Federal Government Adoption of Internet Protocol Version 6 (IPv6) memorandum. Microsoft Office 365 for Government is a multi-tenant service that stores US government data in a segregated community cloud. Like other Office 365 offerings, it provides productivity and collaboration services, including Exchange Online, Lync Online, SharePoint Online, and Office Professional Plus. The Microsoft Office 365 government offerings apply only for 2013 and later. For more information about the Office 365 government offerings, see Announcing Office 365 for Government: A US Government Community Cloud. International Traffic in Arms Regulations (ITAR) is a set of US government regulations that control the export and import of defense-related articles and services on the United States Munitions List (USML). Microsoft Office 365 for Enterprises provides dedicated hosting services for Microsoft productivity solutions that support the security, privacy, and regulatory compliance requirements for US federal agencies requiring Federal Information Security Management (FISMA) certification and commercial entities subject to ITAR. For more information, see Microsoft Office ITAR-Support Service and Network Descriptions and Federal Government Adoption of Internet Protocol Version 6 (IPv6).

We recommend that you do not disable IPv6. For more information, see IPv6 for Microsoft Windows: Frequently Asked Questions. To determine what IP versions are being used on your network, consider the following:

  • If the display of the IPConfig command at the command prompt contains rows named “IPv6 Address” or “Temporary IPv6 Address,” you have IPv6 in your environment.

  • If all the IPv6 addresses begin with “fe80” and correspond to rows named “Link-Local IPv6 Address,” you don’t have IPv6 in your environment.

These considerations might apply to your network:

  • The public subscription service does not support purchase by credit card over IPv6. This does not apply to the Government Community Cloud (GCC) because governments have Enterprise Agreement (EA) licensing.

  • IPv6 does not support some Rights Management Services (RMS) scenarios.

  • IPv6 does not support BlackBerry® Enterprise Server (BES) because BlackBerry doesn’t support IPv6.
