 If your BLOCKS Server will be part of an existing network that has a local DNS server, all you  need to do is adding a name for your BLOCK Server to your DNS, pointing it to the fixed IP address of the BLOCKS server.
-If you're setting up a new network for use by BLOCKS, displays and other clients, you may want the server running BLOCKS to also act as a local DNS. Such functions are already installed and pre-configured in the Linux OS image. See [[#introducing_webmin|below]] for how to enable those services, and where to find their settings.

+=== Server Redundancy (Mirror server) ===
+While the Blocks server software is very robust, the complete system can never be more reliable than the hardware it runs on. If your Blocks server dies for some reason, your system will stop functioning. To safeguard agains such major disasters, you can install a //secondary// Blocks server in your system.

+Specialized mirroring software running in the background keeps this second server in lock-step with the primary server – copying all changes across as they happen in real time. Should the main server die, you can immediately switch over to the mirror copy, and be back up and running in a matter of minutes.
