 == Setting the cluster node hostnames through DHCP
 
-On {op-system-first} machines, the hostname is set through NetworkManager. By default, the machines obtain their hostname through DHCP. If the hostname is not provided by DHCP, it is obtained through a reverse DNS lookup. Reverse DNS lookup occurs after the network has been initialized on a node and can take time to resolve. Other system services can start prior to this and detect the hostname as `localhost` or similar. You can avoid this by using DHCP to provide the hostname for each cluster node.

 Additionally, setting the hostnames through DHCP can bypass any manual DNS record name configuration errors in environments that have a DNS split-horizon implementation.

+a|You can configure an IP address without assigning a static hostname. If a static hostname is not set by the user, it will be picked up and automatically set by a reverse DNS lookup. To configure an IP address without a static hostname:
+
+* The node's IP address to `10.10.10.2` +
+* The gateway address to `10.10.10.254` +
+* The netmask to `255.255.255.0` +
+* The DNS server address to `4.4.4.41`
+* The auto-configuration value to `none`. No auto-configuration is required when IP networking is configured statically.
