3.1.8.1 Client Subnet Record
A Client Subnet Record is described by a NULL-terminated Unicode string containing a list of IPv4 or IPv6 subnets and the subnet length, as described in DNS_RPC_CLIENT_SUBNET_RECORD (section 2.2.15.2.1). For example:
{"southasia", {201.37.23.0/24, 201.58.16.00/20}}
This example creates a Client Subnet Record for the region "southasia" containing the subnets 201.37.23.0/24 and 201.58.16.00/20.
