Each node proxies that port (the same port number on every Node) into your Service.
Your Service reports the allocated port in its `.spec.ports[*].nodePort` field.
If you want to specify particular IP(s) to proxy the port, you can set the `--nodeport-addresses` flag in kube-proxy to particular IP block(s); this is supported since Kubernetes v1.10.
This flag takes a comma-delimited list of IP blocks (e.g. 10.0.0.0/8, 192.0.2.0/25) to specify IP address ranges that kube-proxy should consider as local to this node.

This flag takes a comma-delimited list of IP blocks (e.g. `10.0.0.0/8`, `192.0.2.0/25`) to specify IP address ranges that kube-proxy should consider as local to this node.
For example, if you start kube-proxy with the `--nodeport-addresses=127.0.0.0/8` flag, kube-proxy only selects the loopback interface for NodePort Services. The default for `--nodeport-addresses` is an empty list. This means that kube-proxy should consider all available network interfaces for NodePort. (That's also compatible with earlier Kubernetes releases).
