IP range of google GCM push notification server?

Question

Wonder if anyone here happen to know the ip range of google's gcm server (for android push notification)?

I need the information so that our network team can open the firewall port for our UAT environment for incoming UAT test.

I tried to lookup from developer.android.com/google/gcm/‎ but no luck.

Our network team refused to open all ip range from asn 15169 which is a rather huge list.

I think there is an existing question IP address for Google Cloud Messaging server and the person found out that those are not published by Google. I also tried to look for it once but couldn't find. I might be wrong but I am pretty sure they don't publish that. Maybe instead of using corporate wifi, you can use direct 3G or 4G data plan.

In a comment on why GCM is not giving push notification in android device? question someone has mentioned that He opened the ports 5258,29,30 and then he was able to receive the regId from GCM server behind firewall.

Also I think the answer by @Eran on Which port and protocol does Google Cloud Messaging (GCM) use? will be of help. It says:

The device accesses the GCM servers on ports 5228-5230. If your organization has a firewall that restricts the traffic to or from the Internet, you'll need to configure it to allow connectivity with GCM. The ports to open are: 5228, 5229, and 5230. GCM typically only uses 5228, but it sometimes uses 5229 and 5230. GCM doesn't provide specific IPs. It changes IPs frequently. We recommend against using ACLs but if you must use them, take a broad approach such as the method suggested in this support link.

This is relevant if your device is connected to the internet via WiFi.

Hope this helps a bit.

Update:

As per Mark Whitaker answer to a similar question here, he mentions that:

Newer versions of Android also fall back to port 443 if ports 5228-5230 are blocked by a firewall.

Although there doesn't seem to be an official list still.
