The destination IP address of this route.
The type of this address is determined by the value of
the rlInternInetCidrRouteDestType object.
The values for the index objects rlInternInetCidrRouteDest and
rlInternInetCidrRoutePfxLen must be consistent. When the value
of rlInternInetCidrRouteDest (excluding the zone index, if one
is present) is x, then the bitwise logical-AND
of x with the value of the mask formed from the
corresponding index object rlInternInetCidrRoutePfxLen MUST be
equal to x. If not, then the index pair is not
consistent and an inconsistentName error must be
returned on SET or CREATE requests.
