 * Usually a webserver is reachable with multiple identifiers: its IP addresses, registered
 * domain names, and even `localhost` when connecting from the server itself. Each of a web server's
 * names is a distinct URL and they are not interchangeable. For example, even if
 * `http://square.github.io/dagger` and `http://google.github.io/dagger` are served by the same IP
 * address, the two URLs identify different resources.

 * Integration tests require system properties:
 * - rdma.test.enabled=true (to enable RDMA integration tests)
 * - rdma.test.server=hostname/IP (target server for testing)
 * - rdma.test.port=445 (target port, defaults to 445)

* Only use the first IP address got from instance metadata. This is because Azure CNI would set up a list of IP addresses in instance metadata, while only the first one is the Node's IP. ([#71736](https://github.com/kubernetes/kubernetes/pull/71736), [@feiskyer](https://github.com/feiskyer))

- Kube-proxy IP family will be determined by the nodeIP used by the proxier. The order of precedence is:
  1. the configured --bind-address if the bind address is not 0.0.0.0 or ::
  2. the primary IP from the Node object, if set.
