This chapter laid the foundation for creating networks and subnets that can be utilized by instances and other virtual and physical devices. Both the Horizon dashboard and the OpenStack command-line client can be used to manage networks, subnets, and ports, though the latter is recommended for most administrative tasks.
For more information on network, subnet, and port attributes, as well as for guidance on how to use the Neutron API, refer to the OpenStack wiki at https://developer.openstack.org/api-ref/network/v2/index.html.
In the next chapter, we will learn the basics of creating instances and attaching them to networks. Some of the networks built in this chapter will be used to demonstrate the creation of ports that can be attached to instances with the end goal of end-to-end connectivity.
