We have a secure network that doesn't allow internet access. Unfortunately one app from the Android Market we purchased for our honeycomb tablets uses Market License Check to verify that we've purchased the app on, what it seems like, a daily basis. What site(s) do we have need to allow access to for this authentication to happen?

Unfortunately I can't find any info on this. If you don't get a definite answer I would try allowing and subdomains. – Matthew Read Aug 10 '11 at 17:30
That might be tricky as we want to block users from using the android market. – Michael Aug 10 '11 at 17:33
This could help with blocking it on devices. Assuming the licence server is part of, you'd need the specific ports used as well. This could be used to sniff the traffic and determine the info you need. – Matthew Read Aug 10 '11 at 17:39
BTW, the first link only applies to paid Google Apps accounts not locking down a tablet. – Michael Aug 17 '11 at 12:43

The answer is "" with port 5228 (TCP).

tablet IP address trace – Michael Aug 16 '11 at 21:00
And you can still block users from the Market too? Impressive find! – afrazier Aug 17 '11 at 13:25
Opening the port above also allows the market app to download software so to prevent that we are removing the market app from the tablets. – Michael Aug 17 '11 at 13:55
