Nulling an IP address makes that IP completely unreachable to the external world (the Internet). You might want that in case you need to make your Virtual Server inaccessible without powering it off. The customer will also lose access to the Virtual Server. Once it’s nulled, it will only be reachable using the Remote Console. Note that each time you Null or Un-null, you might need to wait up to 15 minutes before the task is completed (a message is shown with this information).
Although it’s not mandatory, the reverse DNS name is usually required by some Internet Services (such as mailing). You may have to configure your own entry.
