ippool

README

ippool is a dead simple IP pool to simulate the behavior of a DHCP server's ip pool. It was designed to return sequentially generated IPs meant to have short lease periods, working with a fairly small number of used IPs. Working with a almost exhausted pool will lead to longer waiting times retrieving new IPs.

Types

type Dhcpc

type Dhcpc struct {
	Network *net.IPNet
	// contains filtered or unexported fields
}

func New

func New(network string) (*Dhcpc, error)

func (*Dhcpc) IPv4

func (d *Dhcpc) IPv4() net.IP

IPv4 returns the next free IPv4 or nil if the pool is exhausted.

func (*Dhcpc) Release4

func (d *Dhcpc) Release4(ip net.IP)

type GenIP4

type GenIP4 struct {
	// contains filtered or unexported fields
}

GenIP4 is a sequential IPv4 generator.

func NewGenIP4

func NewGenIP4(network string) (*GenIP4, error)

NewGenIP4 creates a new IPv4 address's generator for the given CIDR network, returning an error if it's not in the right format or is invalid.

func (*GenIP4) NextIP

func (p *GenIP4) NextIP() (byte, byte, byte, byte)
