Functions

func GetHostIP

func GetHostIP() (net.IP, error)

HostIP tries to find an IP that can be used by other machines to reach this machine.

func GetLocalAddrs

func GetLocalAddrs() ([]*net.IPNet, error)

func GetLocalFirstIP

func GetLocalFirstIP() (string, error)

func GetLocalFirstMac

func GetLocalFirstMac() (string, error)

func GetLocalIPs

func GetLocalIPs() ([]string, error)

func GetLocalMacs

func GetLocalMacs() ([]string, error)

func IsIPv4

func IsIPv4(netIP net.IP) bool

IsIPv4 returns if netIP is IPv4.

func IsIPv4String

func IsIPv4String(ip string) bool

func LookupHostIPv4

func LookupHostIPv4(host string) (addrs []string, err error)

func LookupHostIPv4WithContext

func LookupHostIPv4WithContext(ctx context.Context, host string) (addrs []string, err error)

func ParseIP

func ParseIP(s string) net.IP

ParseIP parses s as an IP address, returning the result. The string s can be in IPv4 dotted decimal ("192.0.2.1"), IPv6 ("2001:db8::68"), or IPv4-mapped IPv6 ("::ffff:192.0.2.1") form. If s is not a valid textual representation of an IP address, ParseIP returns nil.

func SplitHostIntPort

func SplitHostIntPort(s string) (string, int, error)

SplitHostIntPort split host and integral port
