Functions

func AddrBits

func AddrBits(ip net.IP) int

Return the length of a full prefix (no subnetting) for the given IP address. Returns 32 for ipv4 addresses, and 128 for ipv6 addresses.

func AllInterfaceAddrs

func AllInterfaceAddrs() ([]net.Addr, error)

Return all IP addresses that are currently in use on the local host.

This function differs from net.InterfaceAddrs() in that peer addresses for point-to-point interfaces are returned by this function, in addition to local interface addresses.

func GetDialIP

func GetDialIP(addr string) (net.IP, *net.IPNet, error)

func IncIP

func IncIP(ip net.IP)

func Ip2IPnet

func Ip2IPnet(ip net.IP) *net.IPNet

func IsLocallyAssigned

func IsLocallyAssigned(addr, lower, upper net.IP) bool

func NextIP

func NextIP(lower, upper net.IP) (net.IP, error)

return the next available IP address in the range of provided IPs
