+#       Returns an array suitable for passing to a defined type to create zone files.
+#    Arguments are a base subnet and the CIDR number, example 10.1.0.0/22
+#    This function uses the Net::Addr gem, gem install netaddr
+#    We specifically ask for the address given to be split into class C subnets
+#    in the future it may be extended to deal with other CIDR classes.
+#
+#    For example:
+#
+#        args[0] = 10.1.0.0/22 which returns ["10.0.0.0/24", "10.1.1.0/24", "10.1.2.0/24", "10.1.3.0/24"]
