ipnetgen
-- import "github.com/korylprince/ipnetgen"
Package ipnetgen provides a way to iterate over the addresses in a subnet:
gen, err := New("192.168.100.0/24")
if err != nil {
//do something with err
}
for ip := gen.Next(); ip != nil; ip = gen.Next() {
//do something with ip
}
ipnetgen works on net.IPs, meaning it supports both IPv4 and IPv6 addresses.
Usage
func Increment
func Increment(ip net.IP)
Increment increments the given net.IP by one bit. Incrementing the last IP in an IP space (IPv4, IPV6) is undefined.
type IPNetGenerator
type IPNetGenerator struct {
*net.IPNet
}
IPNetGenerator is a net.IPnet wrapper that you can iterate over
func New
func New(cidr string) (*IPNetGenerator, error)
New creates a new IPNetGenerator from a CIDR string, or an error if the CIDR is invalid.
func NewFromIPNet
func NewFromIPNet(ipNet *net.IPNet) *IPNetGenerator
NewFromIPNet creates a new IPNetGenerator from a *net.IPNet
func (*IPNetGenerator) Next
func (g *IPNetGenerator) Next() net.IP
Next returns the next net.IP in the subnet
