Improvement for k8s.io/docs/concepts/cluster-administration/networking/

[sjmudd]

The description is good but I think could add additional comments.

• use of NAT in ipv4 which is common but I believe not used by everyone
• is NAT used in IPv6?
• cluster access to / from the outside world
• load balancer connectivity to k8s is often provided by a cloud vendor but needs/can be setup if building k8s outside a cloud. what networking considerations need to be considered?
• use of routing within the k8s cluster and to/from the k8s cluster
• how static is the configuration once defined? e.g. can you modify the configuration once the cluster is running?

I think that mentioning these additional points briefly would be helpful. I’m still learning k8s but have bumped into these questions when trying to setup a homelab k8s cluster and found it hard to adjust the configuration if it was not initially correct.

Thanks for considering adding a bit more detail to cover these points.
