List of Download Servers for Creative Cloud?

Hi!  Our corporate network is behind a rather tight firewall and web gateway arrangement.  When we try to download Adobe products (either Creative Suite or Acrobat DC), our firewall/gateway block it.  Logs show that Adobe redirects download requests to one of quite a few different download servers.  Trying to put in rules for each server is a real pain.  Is there either 1.) an authoritative download server where we can always point our client PCs to, or 2.) a definitive list of download servers used in US / Germany that we whitelist?  I don't want to go through the hassle of setting up a separate Adobe update server, not am I thrilled with having to do SCCM packages for each product.  We have the Team option.
