It depends on the host's own address. And I've forgotten what we said that
was by now. ;-)

A host route is one that specifies a specific address, i.e. the mask is
255.255.255.255. I doubt there are restrictions to that either, although,
obviously, you have to point to a local default gateway and not just any old
address.

But there are restrictions to other routes, depending on the bit pattern.
I'm using different addresses than in our example and don't really feel like
twidling bits, but I was able to do something like this:

My address is 100.100.100.17 255.255.255.224

I can:

route add 100.100.100.16 mask 255.255.255.240 gateway

That causes the packets for 100.100.100.16/28 to go through the gateway
router.

I can't do the following though. Windows 98 gives an error message and won't
add the route:

route add 100.100.100.2 mask 255.255.255.240 gateway

I can do this though:

route add 100.100.100.2 mask 255.255.255.254 gateway

I think that would work, if I understand what you're saying. For example, if
you had a host-specific route on the router that pointed to the serial
interface, I think the router would proxy ARP for requests to find that
host. If you also had a host loally with that same address, the requester
would get 2 replies, though, and that would be ugly.

Feel free to try it though (but after dinner!) ;-)
