func GetDefaultPhantomSubnets() *pb.PhantomSubnetsList

GetDefaultPhantomSubnets implements the

func GetUnweightedSubnetList(subnetsList *pb.PhantomSubnetsList) ([]*net.IPNet, error)

Just returns the list of subnets provided by the protobuf. Convenience function to not have to export getSubnets() or parseSubnets()

func SelectAddrFromSubnetOffset(net1 *net.IPNet, offset *big.Int) (net.IP, error)

SelectAddrFromSubnetOffset given a CIDR block and offset, return the net.IP

func SelectPhantom(seed []byte, subnetsList *pb.PhantomSubnetsList, transform SubnetFilter, weighted bool) (*net.IP, error)

SelectPhantom - select one phantom IP address based on shared secret

func SelectPhantomUnweighted(seed []byte, subnets *pb.PhantomSubnetsList, transform SubnetFilter) (*net.IP, error)

SelectPhantomUnweighted - select one phantom IP address based on shared secret

func SelectPhantomWeighted(seed []byte, subnets *pb.PhantomSubnetsList, transform SubnetFilter) (*net.IP, error)

SelectPhantomWeighted - select one phantom IP address based on shared secret

func V4Only(obj []*net.IPNet) ([]*net.IPNet, error)

V4Only - a functor for transforming the subnet list to only include IPv4 subnets

func V6Only(obj []*net.IPNet) ([]*net.IPNet, error)

V6Only - a functor for transforming the subnet list to only include IPv6 subnets

type Choice struct {
	Subnets []string
	Weight  int64
}

type SubnetFilter func([]*net.IPNet) ([]*net.IPNet, error)

SubnetFilter - Filter IP subnets based on whatever to prevent specific subnets from

inclusion in choice. See v4Only and v6Only for reference.
