Is there a way to get the PID information for the host network namespace?

I am writing a script that gathers information about containers running within kubernetes that utilize network namespaces to write a CSV with the following information: "Network Namespace", "Network IP", "Protocol", "Local address", "Remote address", "Status", "PID", "Program name" The problem I am running into is I can easily gather the pids running within a network namespace utilizing "ip netns pids " but can't figure out a way to get the same information for the host itself. Any insight would be helpful!
