Library /sys$common/syshlp/tcpip$ucp_help.hlb SET, ROUTE, Qualifiers, /NETWORK  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Optional. Defaults:

    o  Destination is classified based on its Internet network class
       (A, B, or C).

    o  If the address is clearly a network number, SET ROUTE
       interprets the number correctly.

    Defines the route as a network route.

    Use this qualifier if the network number could be misinterpreted
    as an IP host address, for example, if a network mask is
    nonstandard, or if the IP address is abbreviated.
