Cannot find list of IPs/Domains for Microsoft Entra Cloud Sync

Question

Hello,

Working on firewall rules for Microsoft Entra Cloud Sync from on-prem to cloud. When looking for Entra ports Microsofty provides a link to https://learn.microsoft.com/en-us/entra/identity/hybrid/connect/reference-connect-ports#table-1---microsoft-entra-connect-and-on-premises-ad

But for IPs and Domains, it redirects me to a general list for O365 https://learn.microsoft.com/en-us/microsoft-365/enterprise/urls-and-ip-address-ranges?view=o365-worldwide&redirectSourcePath=%252farticle%252fOffice-365-URLs-and-IP-address-ranges-8548a211-3fe7-47cb-abb1-355ea5aa88a2

I am looking for sites only needed for Entra and not all ports for Office 365. Has anyone found a list just for Entra?

Hi @Robert Rahn

Thank you for reaching out to the community forum!

There is no specific list of IP addresses and domains that are required only for Microsoft Entra Cloud Sync. Microsoft Entra Cloud Sync is a component of the Microsoft 365 and Office 365 services and shares the same IP addresses and domains. This is why the Office 365 URLs and IP address ranges list can be used to identify the necessary IP addresses and domains for Microsoft Entra Cloud Sync.

You can use the Office 365 URLs and IP address ranges list to identify the IP addresses and domains that are required for Entra.

Hope this helps. Do let us know if you any further queries.

Thanks,

Akhilesh.
