Functions

func GetHostByName

func GetHostByName(hostname string) (string, error)

Get the IPv4 address corresponding to a given Internet host name.

func GetHostsByName

func GetHostsByName(hostname string) ([]string, error)

Get a list of IPv4 addresses corresponding to a given Internet host name.

func GetNameByAddr

func GetNameByAddr(ipAddress string) (string, error)

Get the Internet host name corresponding to a given IP address.

func GetSegment

获得ip的网段，例如：192.168.2.102 -> 192.168.2

func IntranetIP

func IntranetIP() (ips []string, err error)

获取本地局域网ip列表

func Ip2long

func Ip2long(ipAddress string) uint32

IP字符串转为整形.

func IsIntranet

func IsIntranet(ipStr string) bool

func Long2ip

func Long2ip(properAddress uint32) string

ip整形转为字符串

func ParseAddress

func ParseAddress(addr string) (string, int)

解析地址，形如：192.168.1.1:80 -> 192.168.1.1, 80

func Validate

func Validate(ip string) bool

判断所给地址是否是一个IPv4地址
