Two questions related to activation...

Adobe tech support has not been very impressive on answering either one of these, so I thought I'd see if anyone here might be of more help.

1. We have a group of Mac's that are segmented off via VLAN from most internet access.  We do open a few very specific IPs for them, but otherwise there is no network path out.  (NOT blocking via proxy server - this is all handled via VLAN/gateway/routing.)   Can anyone tell me the IPs that I need to open up to allow them to activate Creative Cloud and keep it running month-to-month?  Adobe provided URLs/ports and obviously I can resolve them myself, but I was hoping there was a more official list so I didn't run the risk of a DNS change on their end causing me problems down the road.

2. We are a little over half way through deploying InDesign CC on a dozen computers.  The computers are essentially identical configurations and are connected to the exact same network.  All of them but one activate without issue.  The problem child has nothing unique about it and I've tried the gambit of uninstall/reinstall, deleting OPM.DB, etc.and I still receive the "Internet connection is required..." message when attempting to activate.  The machine does have internet access and as stated before it is the exact same proxy configuration as several other machines that are working perfectly. Can anyone offer some 'deeper' troubleshooting suggestions?

Thanks in advance...
