# US-East-1 Has 5 availability zones, and we want to split our network over all
# of them. So we will do a /19 per AZ which will give us the ability to expand
# up to 8 total AZs or to add more capacity in 3/5 of the other AZs if need be.
# If for some reason this is being run in a region with less AZs, we will just
# have more left over capacity being reserved as a spare. In addition, we will
# split our allocation within each AZ up into a /20 for all of our private
# instances, a /21 for all of our public instances, and a /21 left over for
# spare capacity. This will give us the largest block of IP addresses for our
# private tier, where most of our instances will reside, while still leaving
# spare allocation for the future.
