STATIC resolution support

AFAIK, when generate endpoints, istio only support DNSLB, current istio implementing following:

func buildLocalityLbEndpoints(env *model.Environment, proxyNetworkView map[string]bool, service *model.Service,
	port int, labels labels.Collection) []*endpoint.LocalityLbEndpoints {

	if service.Resolution != model.DNSLB {
		return nil
	}

	instances, err := env.InstancesByPort(service, port, labels)
	if err != nil {
		log.Errorf("failed to retrieve instances for %s: %v", service.Hostname, err)
		return nil
	}
...

Does it mean endpoint generate only support DNS resolution？ thx
