Functions ¶

func IsLocal ¶

func IsLocal(host string) bool

IsLocal returns if the host is the localhost address.

func JoinHostPort ¶ added in v1.0.2

func JoinHostPort(host string, port uint16) string

JoinHostPort joins the host/IP address and the port number,

func LoadLocalIP ¶ added in v1.0.0

func LoadLocalIP() string

LoadLocalIP returns local ip address

func Parse ¶

func Parse(addr string) (host string, port uint16, isLocal, isIPv4, isIPv6 bool, err error)

Parse parses the hostname, IPv4 or IPv6 address and return the hostname/IP, port number, whether the address is local IP and IPv4 or IPv6, and any parsing error occurred. The address should contains the port number, otherwise an error will return.

func ScanPorts ¶

func ScanPorts(ctx context.Context, start, end uint16, host string) (ports []uint16, err error)

ScanPorts scans the given range of port numbers from the host (inclusively), and return the list of ports that can be connected through TCP, or any error occurred.

func SplitHostPort ¶

func SplitHostPort(hostport string) (host string, port uint16, err error)

SplitHostPort splits the address, and return the host/IP address and the port number, and any error occurred. If it is the loopback address, it will return the loopback address and corresponding port number. IPv6 loopback address is not supported yet.
