LFS258 Exercise 9.2: Configure a NodePort

When I do  kubectl -n accounting expose deployment nginx-one --type=NodePort --name=service-lab

The NodePort Service is exposed using 10.96.252.250.

admin_isergei_altostrat_com@cp:~$ kubectl get service -n accounting
service-lab  NodePort  10.96.252.250      80:31154/TCP  23h

Where does this 10.96.252.250 is coming from and how do I expose the service using the Public IP address of the node? Because in the lab description it is mentioned that I should be able to access the nginx using the public IP of the node.

From the lab:
"Using the browser on your local system, use the public IP address you use to SSH into your node and the port. You should still see the nginx default page."
