 = Setting the cluster node hostnames through DHCP
 
-On {op-system-first} machines, hostnames are is set through `NetworkManager`. 
-By default, the machines obtain their hostnames through DHCP. 
-If hostnames are not provided by DHCP, set statically through kernel arguments, or another method, they are 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 hostnames as `localhost` or similar. 
-You can avoid this delay in assigning hostnames by using DHCP to provide the hostname for each cluster node.
+On {op-system-first} machines, `NetworkManager` sets the hostnames. By default, DHCP provides the hostnames to `NetworkManager`, which is the recommended method. `NetworkManager` gets the hostnames through a reverse DNS lookup in the following cases:
 
-Additionally, setting the hostnames through DHCP can bypass any manual DNS record name configuration errors in environments that have a DNS split-horizon implementation.
+* If DHCP does not provide the hostnames
+* If you use kernel arguments to set the hostnames
+* If you use another method to set the hostnames
 
+Reverse DNS lookup occurs after the network has been initialized on a node, and can increase the time it takes `NetworkManager` to set the hostname. Other system services can start prior to `NetworkManager` setting the hostname, which can cause those services to use a default hostname such as `localhost`.
