Functions

func DeriveGatewayIP

func DeriveGatewayIP(cidr string) string

DeriveGatewayIP gateway ip from cidr

func GetIPAtIndex

func GetIPAtIndex(ipNet net.IPNet, index int64) net.IP

GetIPAtIndex get the IP by index in the range of ipNet. The index is start with 0.

func GetNextIP

func GetNextIP(ip net.IP) net.IP

GetNextIP returns the next IP from the given IP address. If the given IP is the last IP of a v4 or v6 range, the same IP is returned.

func IPs2str

func IPs2str(ips []net.IP) []string

func IPsHasAll

func IPsHasAll(a []net.IP, b []net.IP) bool

IPsHasAll return true if all b is in a

func IPsIntersect

func IPsIntersect(a []net.IP, b []net.IP) bool

IPsIntersect return is 2 set is intersect

func IPv6

func IPv6(ip net.IP) bool

func NetEqual

func NetEqual(ipn1 *net.IPNet, ipn2 *net.IPNet) bool

NetEqual returns true if both IPNet are equal

func ToIP

func ToIP(addr string) (net.IP, error)

ToIP parse str to net.IP and return error is parse failed

func ToIPMap

func ToIPMap(addrs []net.IP) map[string]net.IP

func ToIPs

func ToIPs(addrs []string) ([]net.IP, error)
