Customers are sometimes in need to assign new IP addresses for new projects. Virtual IPs are usually created in the compute nodes and based on the current default configuration (or what was configured during the set up of the system) new IPs are needed. For that is necessary to modify the "network mask" so new IPs can be created on InfiniBand network.
For example, all IPs of this network from 172.24.16.0 until 172.24.16.255 are busy for several projects, and you need to configure other new IPs but the current network mask is set to 255.255.255.0 and no IPs available for allocation.
