Functions

func BroadcastIPAddress

func BroadcastIPAddress(network *net.IPNet) net.IP

BroadcastIPAddress returns the broadcast IP address for the given network, which is obtained by bitwise OR'ing the network IP address with the negated mask, i.e. by basically turning on the mask's zero bits in the network IP address.

Example: 1.1.1.0/24 => 1.1.1.255

func ParseNetworkCIDR

func ParseNetworkCIDR(s string) (*net.IPNet, error)

ParseNetworkCIDR uses net.ParseCIDR() but returns an error if the returned IP address is not equal the network IP address.
