In a private cloud datacenter, to prevent users from creating private networks that use a certain network address range, you can reserve the range by creating an excluded network.
The name of the network to exclude of up to 128 characters
|IPv6||To exclude an IPv6 network, select this checkbox|
The network address of the network to exclude
The network mask in CIDR format. For IPv4, the networks created in the platform the netmask can have a value from 16 to 30 inclusive, and for IPv6, it can have a value of 64, 56, or 48.
The platform will exclude the network range. Users with existing private networks within the excluded range can continue to work with them. But if the users delete the networks, they will not be able to create them again.
