Functions

func AddEdnsPadding

func AddEdnsPadding(msg *dns.Msg) (*dns.Msg, error)

Add EDNS padding, as defined in RFC7830, to a raw DNS message.

func NewOdohTransport

func NewOdohTransport(id, endpoint, target string, addrs []string, px ipn.Proxies, ctl protect.Controller) (dnsx.Transport, error)

NewTransport returns a POST-only Oblivious DoH transport. `id` identifies this transport. `endpoint` is the ODoH proxy that liasons with the target. `target` is the ODoH resolver. `addrs` is a list of IP addresses to bootstrap endpoint dialers. `px` is the proxy provider, never nil.

func NewTransport

func NewTransport(id, rawurl string, addrs []string, px ipn.Proxies, ctl protect.Controller) (dnsx.Transport, error)

NewTransport returns a POST-only DoH transport. `id` identifies this transport. `rawurl` is the DoH template in string form. `addrs` is a list of IP addresses to bootstrap dialers. `px` is the proxy provider, may be nil (eg for id == dnsx.Default)
