+1 The local resolver (/etc/resolv.conf) will works more compatible than others.
Cases like : we use Aliyun & K8s cluster, if we set `dns_resolver` to the IPs outside vpc network, some feature will be broken: Aliyun DNS `private zone` record cannot be fetch any more; K8s' inner service record like: `*.*.svc.cluster.local｀cannot be reached any more; Fetching Aliyun's resource link url like `*.aliyuncs.com` will cause big latency than default. 在 2020年3月26日星期四，junxu chen <[email protected]> 写道： > +1 > > I prefer use the local DNS resolver by default.
