I agree with Emmanuel, and ask one question : are those addresses assigned
to routers interfaces ?
In that case, I am not sure of whether you can ask netmon to discover only
part of a device : during a poll for config, netmon 'sees' all interfaces of
a router, what happens if an interface is assigned an address defined as
negative entry in the seed file ?
