Allowed IP addresses and domain URLs

  • Article

TFS 2017 | TFS 2015

If your organization's secured with a firewall or proxy server, you must add certain internet protocol (IP) addresses and domain uniform resource locators (URLs) to the allowlist. Adding these to the allowlist helps to ensure that you have the best experience with Azure DevOps. You know that you need to update your allowlist if you can't access Azure DevOps on your network. See the following sections in this article:

Tip

So that Visual Studio and Azure Services work well with no network issues, you should open select ports and protocols. For more information, see Install and use Visual Studio behind a firewall or proxy server, Use Visual Studio and Azure Services.

Domain URLs to allow

Network connection issues could occur because of your security appliances, which may be blocking connections - Visual Studio uses TLS 1.2 and above. When you're using NuGet or connecting from Visual Studio 2015 and later, update the security appliances to support TLS 1.2 and above for the following connections.

To ensure your organization works with any existing firewall or IP restrictions, ensure that dev.azure.com and *.dev.azure.com are open.

The following section includes the most common domain URLs to support sign in and licensing connections.


https://*.dev.azure.com
https://*.vsassets.io
https://*gallerycdn.vsassets.io

Various domain URL descriptions
  • https://*gallerycdn.vsassets.io: hosts Azure DevOps extensions
  • https://*vstmrblob.vsassets.io: hosts Azure DevOps TCM log data
  • https://cdn.vsassets.io: hosts Azure DevOps Content Delivery Networks (CDNs) content
  • https://static2.sharepointonline.com: hosts some resources that Azure DevOps uses in "office fabric" UI kit for fonts, and so on
  • https://vsrm.dev.azure.com: hosts package feeds

We recommend you open port 443 to all traffic on these IP addresses and domains. We also recommend you open port 22 to a smaller subset of targeted IP addresses.

Note

Azure DevOps uses Content Delivery Networks (CDNs) to serve static content. Users in China should also add the following domain URLs to an allowlist:

https://*.vsassetscdn.azure.cn
https://*.gallerycdn.azure.cn

More domain URLs

Azure Artifacts

Ensure the following domain URLs are allowed for Azure Artifacts:

https://*.blob.core.windows.net
https://*.visualstudio.com

Also allow all IP addresses in the "name": "Storage.{region}" section of the following file (updated weekly) : Azure IP ranges and Service Tags - Public Cloud. {region} is the same Azure Geography as your organization.

NuGet connections

Ensure the following domain URLs are allowed for NuGet connections:

https://azurewebsites.net
https://nuget.org

Note

Privately owned NuGet server URLs might not be included in the previous list. You can check the NuGet servers you're using by opening %APPData%\Nuget\NuGet.Config.

SSH connections

If you need to connect to Git repositories on Azure DevOps with SSH, allow requests to port 22 for the following hosts:


ssh.dev.azure.com
vs-ssh.visualstudio.com

Also allow IP addresses in the "name": "AzureDevOps" section of this downloadable file (updated weekly) named: Azure IP ranges and Service Tags - Public Cloud

IP addresses and range restrictions

Outbound connections

Outbound connections originate from inside your organization and that target Azure DevOps or other dependent sites. Examples of such connections include:

  • Browsers connecting to Azure DevOps website as users go to and use features of Azure DevOps
  • Azure Pipelines agents installed on your organization's network connecting to Azure DevOps to poll for pending jobs
  • CI events sent from a source code repository that's hosted within your organization's network to Azure DevOps

Ensure the following IP addresses are allowed for outbound connection, so your organization works with any existing firewall or IP restrictions. The endpoint data in the following chart lists requirements for connectivity from a machine in your organization to Azure DevOps Services.


13.107.6.0/24
13.107.9.0/24
13.107.42.0/24
13.107.43.0/24

If you're currently allowing the 13.107.6.183 and 13.107.9.183 IP addresses, leave them in place, as you don't need to remove them.

Note

Azure Service Tags aren't supported for outbound connection.

Inbound connections

Inbound connections originate from Azure DevOps and target resources within your organization's network. Examples of such connections include:

Ensure the following IP addresses are allowed for inbound connection, so your organization works with any existing firewall or IP restrictions. The endpoint data in the following chart lists requirements for connectivity from Azure DevOps Services to your on-premises or other cloud services.

  Region   IP V4 ranges
Australia East 20.37.194.0/24
Australia South East 20.42.226.0/24
Brazil South 191.235.226.0/24
Central Canada 52.228.82.0/24
Asia Pacific (Singapore) 20.195.68.0/24
South India 20.41.194.0/24
Central United States 20.37.158.0/23
West Central United States 52.150.138.0/24
East United States 20.42.5.0/24
East 2 United States 20.41.6.0/23
North United States 40.80.187.0/24
South United States 40.119.10.0/24
West United States 40.82.252.0/24
West 2 United States 20.42.134.0/23
Western Europe 40.74.28.0/23
United Kingdom South 51.104.26.0/24

Azure Service Tags are supported for inbound connection. Instead of allowing the previously listed IP ranges, you may use the AzureDevOps service tag for Azure Firewall and Network Security Group (NSG) or on-premises firewall via a JSON file download.

Other IP addresses

Most of the following IP addresses pertain to Microsoft 365 Common and Office Online.


40.82.190.38
52.108.0.0/14
52.237.19.6
52.238.106.116/32

Azure DevOps ExpressRoute connections

If your organization uses ExpressRoute, ensure the following IP addresses are allowed for both outbound and inbound connections.

13.107.6.175/32
13.107.6.176/32
13.107.6.183/32

For more information about Azure DevOps and ExpressRoute, see ExpressRoute for Azure DevOps.

Azure DevOps import service

During the import process, we highly recommend that you restrict access to your virtual machine (VM) to only IP addresses from Azure DevOps. To restrict access, allow only connections from the set of Azure DevOps IP addresses, which were involved in the collection database import process. For information about identifying the correct IP addresses, see (Optional) Restrict access to Azure DevOps Services IPs only.
