If you are the senior-most Information Security Officer at your institution, will you please complete the following MonkeySurvey regarding Private vs Publicly-Accessible IP Addresses?
If we happen to be the networking person who actually allocates the addresses, and thus actually know the answer better than the CISO, are we allowed to answer that? Also, are you looking for address space allocated, or address space actually in use? We have a chunk of 1918 space we allocated to the wireless net for IPv4 (they get globally routable IPv6), and the number of wireless users fluctuates of course - we've seen a peak of 11,000+ simultaneous, but it's probably sitting around 2-3K users now. Also, are you talking IPv4, or IPv6? Some of us have lots of both. Also, question 5 is phrased in a leading manner - it assumes that the site uses 1918 addresses by default, as it only asks for people that insisted on having public addresses. There's no similar question for "you assign public addresses by default, and somebody insisted on 1918 space".
