Client implements a DHCPv6 client

func NewClient

func NewClient() *Client

NewClient returns a Client with default settings

func (*Client) Exchange

func (c *Client) Exchange(ifname string, modifiers ...dhcpv6.Modifier) ([]dhcpv6.DHCPv6, error)

Exchange executes a 4-way DHCPv6 request (Solicit, Advertise, Request, Reply). The modifiers will be applied to the Solicit and Request packets. A common use is to make sure that the Solicit packet has the right options, see modifiers.go

func (*Client) Request

func (c *Client) Request(ifname string, advertise dhcpv6.DHCPv6, modifiers ...dhcpv6.Modifier) (dhcpv6.DHCPv6, dhcpv6.DHCPv6, error)

Request sends a Request built from an Advertise. It returns the Request, a Reply (if not nil), and an error if any. The modifiers will be applied to the Request before sending it, see modifiers.go

func (*Client) Solicit

func (c *Client) Solicit(ifname string, modifiers ...dhcpv6.Modifier) (dhcpv6.DHCPv6, dhcpv6.DHCPv6, error)

Solicit sends a Solicit, returns the Solicit, an Advertise (if not nil), and an error if any. The modifiers will be applied to the Solicit before sending it, see modifiers.go
