Functions

func AllocateIP

func AllocateIP(ctx context.Context, ipnet *net.IPNet, iface *net.Interface, bridge *netlink.Bridge) (net.IP, error)

For a given IP network, bridge (and its interface), allocate a free IP address.

func BigIntToIP

func BigIntToIP(v *big.Int) net.IP

BigIntToIP converts 128 bit integer into a 4 bytes IP address.

func BridgeIPs

func BridgeIPs(bridge *netlink.Bridge) ([]string, error)

BridgeIPs returns all the IPs attached to the provided bridge

func IPToBigInt

func IPToBigInt(ip net.IP) *big.Int

IpToBigInt converts a 4 bytes IP into a 128 bit integer.

func IncreaseIP

func IncreaseIP(ip net.IP) net.IP

Increases IP address numeric value by 1.

func IsUnicastIP

func IsUnicastIP(ip net.IP, mask net.IPMask) bool

IsUnicastIP returns true if the provided IP address and network mask is a unicast address.

func NewNetworkServiceV1alpha1

func NewNetworkServiceV1alpha1(ctx context.Context, opts ...any) (networkv1alpha1.NetworkService, error)
