A subnet in Neutron is a Layer 3 object and can be an IPv4 or IPv6 address block defined using classless inter-domain routing (CIDR) notation. CIDR is a method of allocating IP addresses using variable-length subnet masking, or VLSM. Subnets have a direct relationship to networks and cannot exist without them.
More information on CIDR and VLSM can be found on Wikipedia at http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing.
The primary commands associated with subnet management that will be discussed in this chapter are listed in the following table:
