Types

type Client

type Client interface {
	features.Feature

	// LookupIP returns IP address for the given domain. IPs may contain IPv4 and/or IPv6 addresses.
	LookupIP(domain string) ([]net.IP, error)
}

Client is a V2Ray feature for querying DNS information.

type ClientWithIPOption

type ClientWithIPOption interface {
	// GetIPOption returns IPOption for the DNS client.
	GetIPOption() *IPOption

	// SetQueryOption sets IPv4Enable and IPv6Enable for the DNS client.
	SetQueryOption(isIPv4Enable, isIPv6Enable bool)

	// SetFakeDNSOption sets FakeEnable option for DNS client.
	SetFakeDNSOption(isFakeEnable bool)

	// SetFailFastOption sets FailFast option for the DNS client.
	SetFailFastOption(isFailFast bool)
}

ClientWithIPOption is an optional feature for querying DNS information.
