ahh ok.. will have to use 'plan b' then since i have to begin this next week
installing on a replacement server..

hmm... yeah that could cause a bit of problem especially since we run 4 nics
with unique networks in each and various guests address them as they are
configured.. would not do for it to see for example our 38 net and 39 net
each a /24 as one range... would severely mess up vpns and things..

ok so ill just have to plan for no more than 16 ips per guest which severely
increases our license outlay for a program we run in each guest.

we ultimately need to be able to safely and quickly address between 50 and 100
ips per guest to keep our costs down.
