Functions

func HostIPs

func HostIPs() ([]string, []string, error)

HostIPs returns public and private IPs assigned to various interfaces on current host.

func IsPrivateIP

func IsPrivateIP(ip net.IP) bool

func NodeIP

func NodeIP(interfaceName ...string) (string, net.IP, error)

NodeIP returns a IPv4 address for a given set of interface names. It always prefers a private IP over a public IP. If no interface name is given, all interfaces are checked.

func RoutableIPs

func RoutableIPs() ([]string, []string, error)

Types

type IPRange struct {
	// contains filtered or unexported fields
}

func NewIPRange

func NewIPRange(from string, to string) IPRange
