Types

type Resolver

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

Resolver is a structure that is used whenever DNS resolution is required.

TODO(ameshkov): Add --resolve parameter support.

func NewResolver

func NewResolver(cfg *config.Config, out *output.Output) (r *Resolver, err error)

NewResolver creates a new instance of *Resolver.

func (*Resolver) LookupECHConfigs

func (r *Resolver) LookupECHConfigs(hostname string) (echConfigs []ctls.ECHConfig, err error)

LookupECHConfigs attempts to discover ECH configurations in DNS records of the specified hostname. If no ECH configuration can be discovered for this domain, the function returns ErrEmptyResponse (checked via errors.Is/As).

func (*Resolver) LookupHost

func (r *Resolver) LookupHost(hostname string) (ipAddresses []net.IP, err error)

LookupHost looks up all IP addresses of the hostname.
