Azure-docs: IP Filtering when receiving events at an HTTP endpoint

[EddyP23]

We have created an Azure AppServices API that is listening for our EventGrid messages via HTTP endpoints.

On the other hand, we are using IP filtering in our Azure AppServices API, but now we have no mechanism on making sure we don't filter Event Grid messages.

I could not find an IP address that is used by our Event Grid Subscription, nor the list for all EventGrid IPs.

Is there any way we could do IP filtering when also using Event Grid via HTTP endpoints.

@EddyP23 We don't have any specific IP for event grid subscriptions. It can be any IP's from the azure datacenter. If you want to whitelist the IP then we recommend to download all the Microsoft Azure Datacenter IP Ranges from this link https://www.microsoft.com/en-in/download/details.aspx?id=41653 and configure these IP, based on the region of the event grid topic that event grid subscription have configured.
Also we recommend to check these IPs regularly (weekly) as these may change with time (based on updates). The IP address of the service bus changes in case there is a backend update.

Also there is already a user voice on this. Do upvote this for this feature request.
