Functions

func IPLess

func IPLess(a, b net.IP) bool

IPLess IP大小比较 IPv4 < IPv6

func IPNetMaskLess

func IPNetMaskLess(a, b *net.IPNet) bool

IPNetMaskLess CIDR大小比较 IPv4 < IPv6 ones越大，子网范围越小

func IPv4StrToUint32

func IPv4StrToUint32(ipStr string) uint32

IPv4StrToUint32 IPv4字符串 转换为 uint32 (syntactic sugar)

func IPv4ToUint32

func IPv4ToUint32(ip net.IP) uint32

IPv4ToUint32 IPv4 转换为 uint32

func LastIP

func LastIP(ipNet *net.IPNet) net.IP

LastIP IPNet最后一个IP

func NextIP

func NextIP(ip net.IP) net.IP

NextIP 下一个IP

func PrefixSameLength

func PrefixSameLength(start, end net.IP) int

PrefixSameLength 前缀相同长度

func SuffixZeroLength
