Question

MS Teams IPs mentioned in the official doc are not exhaustive

Nainesh Hulke 5

Microsoft has listed the IP address ranges and ports that it uses for MS Teams here.

But I found that there are some IPs which are not listed but are being used for the MS Teams network traffic. The IP address ranges listed by Microsoft are not exhaustive. Also, I found that Skype is also using some of these IPs. This means I can't distinguish between Skype and MS Teams.

How can I tell the difference between MS Teams and Skype network traffic on the basis of IPs and ports?

Following are some examples of IPs used by MS Teams but are not listed: 104.208.16.88, 104.208.16.90, 20.189.173.6, 20.202.41.10, 20.202.41.18, 20.202.41.19, 20.202.41.24

Hi @Nainesh Hulke

I am afraid there is no public documentation about the detailed usage of Microsoft ip addresses.

If possible please consider creating a service request in Microsoft 365 admin center>Support>New service request.

Thanks for the reply.

Can you provide any link for creating a service request? Also, are there any requirements for creating a service request?

Hi,

You can contact support by accessing Microsoft 365 admin center with an admin account (like global admin or other accounts which have permissions), locate Support>New service request.

You must have bought at least one subscription through Microsoft to access Microsoft support. If you bought all your subscriptions through a partner, contact your partner for support.
