1. Proposed title of this feature request

Network observability - labelling unkwon objects 

2. What is the nature and description of the request?

Using the network-observability plugin (v0.2.0) on ocp we found that while inspecting the traffic between pods  there are some nodes that are label as unknown.

3. Why does the customer need this? (List the business requirements here)

We think that it can be more useful to be able to know the sources and destinations of the traffic

OCP v4.12, network-observability plugin (v0.2.0)
