While implementing the netns handling in ifstate I got aware that pyroute2 did not have a netlink RTM_NEWNSID request implementation.

I got https://github.com/svinota/pyroute2/pull/1121 merged into pyroute2 to add RTM_NEWNSID support.

Later I have noticed that my implementation does not work within netns (pyroute2 related, some details in issue https://github.com/svinota/pyroute2/issues/1123 ).

After this tangled journey ifstate netns dev branch now has its first netns superpowers 😎

The correct (unexpected?) answer is: 0

When adding another ipv4 address of an already assigned prefix it becomes a secondary address. Removing the primary ipv4 address of a prefix removes all secondary addresses of the prefix.

A more complex examples is found in the attached screenshot.

For ipv6 there is no secondary ip address concept. The bit in the #netlink datagrams for secondary addresses in ipv4 is used for temporary addresses in ipv6 netlink datagrams.
