func AddIPOffset Uses

func AddIPOffset(base *big.Int, offset int) net.IP

AddIPOffset adds the provided integer offset to a base big.Int representing a net.IP

func BigForIP Uses

func BigForIP(ip net.IP) *big.Int

BigForIP creates a big.Int based on the provided net.IP

func GetIndexedIP Uses

func GetIndexedIP(subnet *net.IPNet, index int) (net.IP, error)

GetIndexedIP returns a net.IP that is subnet.IP + index in the contiguous IP space.

func IsDualStackCIDRStrings Uses

func IsDualStackCIDRStrings(cidrs []string) (bool, error)

IsDualStackCIDRStrings returns if - all are valid cidrs - at least one cidr from each family (v4 or v6)

func IsDualStackCIDRs Uses

func IsDualStackCIDRs(cidrs []*net.IPNet) (bool, error)

IsDualStackCIDRs returns if - all are valid cidrs - at least one cidr from each family (v4 or v6)

func IsDualStackIPStrings Uses

func IsDualStackIPStrings(ips []string) (bool, error)

IsDualStackIPStrings returns if - all are valid ips - at least one ip from each family (v4 or v6)

func IsDualStackIPs Uses

func IsDualStackIPs(ips []net.IP) (bool, error)

IsDualStackIPs returns if a slice of ips is: - all are valid ips - at least one ip from each family (v4 or v6)

func IsIPv6 Uses

func IsIPv6(netIP net.IP) bool

IsIPv6 returns if netIP is IPv6.

func IsIPv6CIDR Uses

func IsIPv6CIDR(cidr *net.IPNet) bool

IsIPv6CIDR returns if a cidr is ipv6

func IsIPv6CIDRString Uses

func IsIPv6CIDRString(cidr string) bool

IsIPv6CIDRString returns if cidr is IPv6. This assumes cidr is a valid CIDR.

func IsIPv6String Uses

func IsIPv6String(ip string) bool

IsIPv6String returns if ip is IPv6.

func ParseCIDRs Uses

func ParseCIDRs(cidrsString []string) ([]*net.IPNet, error)

ParseCIDRs parses a list of cidrs and return error if any is invalid. order is maintained

func ParsePort Uses

func ParsePort(port string, allowZero bool) (int, error)

ParsePort parses a string representing an IP port. If the string is not a valid port number, this returns an error.

func RangeSize Uses

func RangeSize(subnet *net.IPNet) int64

RangeSize returns the size of a range in valid addresses. returns the size of the subnet (or math.MaxInt64 if the range size would overflow int64)

type IPNetSet Uses

type IPNetSet map[string]*net.IPNet

IPNetSet maps string to net.IPNet.

func ParseIPNets Uses

func ParseIPNets(specs ...string) (IPNetSet, error)

ParseIPNets parses string slice to IPNetSet.

func (IPNetSet) Delete Uses

func (s IPNetSet) Delete(items ...*net.IPNet)

Delete removes all items from the set.

func (IPNetSet) Difference Uses

func (s IPNetSet) Difference(s2 IPNetSet) IPNetSet

Difference returns a set of objects that are not in s2 For example: s1 = {a1, a2, a3} s2 = {a1, a2, a4, a5} s1.Difference(s2) = {a3} s2.Difference(s1) = {a4, a5}

func (IPNetSet) Equal Uses

func (s IPNetSet) Equal(s2 IPNetSet) bool

Equal returns true if and only if s1 is equal (as a set) to s2. Two sets are equal if their membership is identical. (In practice, this means same elements, order doesn't matter)

func (IPNetSet) Has Uses

func (s IPNetSet) Has(item *net.IPNet) bool

Has returns true if and only if item is contained in the set.

func (IPNetSet) HasAll Uses

func (s IPNetSet) HasAll(items ...*net.IPNet) bool

HasAll returns true if and only if all items are contained in the set.

func (IPNetSet) Insert Uses

func (s IPNetSet) Insert(items ...*net.IPNet)

Insert adds items to the set.

func (IPNetSet) IsSuperset Uses

func (s IPNetSet) IsSuperset(s2 IPNetSet) bool

IsSuperset returns true if and only if s1 is a superset of s2.

func (IPNetSet) Len Uses

func (s IPNetSet) Len() int

Len returns the size of the set.

func (IPNetSet) StringSlice Uses

func (s IPNetSet) StringSlice() []string

StringSlice returns a []string with the String representation of each element in the set. Order is undefined.
