 * **Cobbler server and Puppet Master.** The heart of a Fuel install is the combination of Puppet Master and Cobbler used to create your resources. Although Cobbler and Puppet Master can be installed on separate machines, it is common practice to install both on a single machine for small to medium size clouds, and that's what we'll be doing in this example.  (By default, the Fuel ISO creates a single server with both services.)
 
 * **Domain name.** Puppet clients generate a Certificate Signing Request (CSR), which is then signed by Puppet Master. The signed certificate can then be used to authenticate the client during provisioning. Certificate generation requires a fully qualified hostname, so you must choose a domain name to be used in your installation. We'll leave this up to you.
-* **Network addresses.** OpenStack requires a minimum of three networks. If you are deploying on physical hardware two of them -- the public network and the internal, or management network -- must be routable in your networking infrastructure. Also, if you intend for your cluster to be accessible from the Internet, you'll want the public network to be on the proper network segment.  For simplicity in this case, this example assumes an Ineternet router at 192.168.0.1.  Additionally, a set of private network addresses should be selected for automatic assignment to guest VMs. (These are fixed IPs for the private network). In our case, we are allocating network addresses as follows:
