Reserved UDP Port Range for NodePort Services
The Ports and Protocols documentation currently describes the port range of 30000-32767 as being reserved only for TCP NodePort services. Kubernetes also uses this range for allocating UDP NodePort services, however this is undocumented. Does Kubernetes expect this range of UDP ports to be reserved as well?
Docs: https://github.com/kubernetes/website/blob/1c5221a29971e1658eff8f116dbb4ffa0605927b/content/en/docs/reference/networking/ports-and-protocols.md?plain=1#L31

For a node port Service, Kubernetes additionally allocates a port (TCP, UDP or SCTP to match the protocol of the Service).
this is mention here about UDP protocols:https://kubernetes.io/docs/concepts/services-networking/service/#type-nodeport
Kubernetes expects the port range 30000-32767 to be reserved for both TCP and UDP NodePort services as of my thinking so need to add UDP documentation here:https://kubernetes.io/docs/reference/networking/ports-and-protocols/
/priority backlog
I haven't checked if UDP NodePorts use the same range as TCP.
