There may be many routes for a single address. For example, a webserver that is hosted in multiple datacenters may yield multiple IP addresses in its DNS response.

}

// endpointSubsetAddressVal returns a map having subset address type for an endpoint.
func endpointSubsetAddressVal(hostname, ip, nodeName string) map[string]any {
	out := make(map[string]any)
	if hostname != "" {
		out["hostname"] = hostname
	}
	if ip != "" {
		out["ip"] = ip
	}
	if nodeName != "" {
		out["nodeName"] = nodeName
	}
	return out
}

Istio 1.0 includes the gateways in istio-system. Since the external IP is associated
with the Service and bound to the namespace, it is recommended to:

1. Install the new gateway in a new namespace.
2. Copy any TLS certificate to the new namespace, and configure the domains.
3. Checking the new gateway work - for example by overriding the IP in /etc/hosts
4. Modify the DNS server to add the A record of the new namespace

   * be logged if the test fails.
   *
   * This client is also configured to be slightly more deterministic, returning a single IP
   * address for all hosts, regardless of the actual number of IP addresses reported by DNS.
