One or more IP addresses with subnet masks that will be used as the virtual IP addresses (VIPs) for load balancing on the internal network adapter. These are usually the current IP addresses on the internal adapter of the server on which the cmdlet is executed. 

Specify the IPv4 address and subnet in the format IP_ADDR/SUBNET. For IPv6 specify the prefix length along with the IP address. 
If ISATAP is deployed in the internal network then at least one of the IP addresses specified in the parameter should be present in the ISATAP name entry in DNS.
The Network Location Server should resolve to at least one of the VIPs
