    .PARAMETER Name NAME          
        Network name
    .PARAMETER InterfaceID ID
        The unique ID of the interface. Only applicable for All-NVMe nodes
    .PARAMETER Netmask (if STATIC) 
        IPv4 or IPv6 Netmask  - 255.255.255.0 
    .PARAMETER IpRanges (if STATIC) 
        List of persistent IP ranges. Can be single addresses or ranges, comma separated. eg. 10.1.1.20-21 or 10.1.1.20,10.1.1.21
    .PARAMETER FloatingIpRanges  (if STATIC) 
        List of floating IP ranges. Can be single addresses or ranges, comma separated. eg. 10.1.1.20-21 or 10.1.1.20,10.1.1.21
    .PARAMETER DnsServers

    .PARAMETER DnsSearchDomains   
        List of DNS Search Domains
    .PARAMETER Mtu (if STATIC) 
        The Maximum Transfer Unit (MTU) in bytes of a tagged STATIC network. The MTU of an untagged STATIC network needs to be specified through interface MTU.
    .PARAMETER VlanID (if STATIC) 
        User assigned VLAN tag for network configuration. 1-4094 are valid VLAN IDs and 0 is used for untagged networks.
    .PARAMETER TenantID (if STATIC) 
        The tenant that the network will be assigned to. If only one tenant exists, the network will default to that tenant. Otherwise, not
        specifying the tenant will create the network unassigned.
