text: Mind you that many hosts (e.g. workstation, laptop) do have multiple network interfaces and could technically act as a router.\n\nIn that case if you are an authorized SNMP manager, you can try to view the machine's ipRouteTable (more on that see http://www.faqs.org/rfcs/rfc2096.html.)  The table's content would tell you if this machine is configured to route/forward IP packets, hence acting as a router.
