To store a single route/gateway for every possible class C network would
take less than 8 megabytes of memory, which is quite possible to do.
The problem is that if you don't have enough additional memory to store
multiple routes, it makes the network unreliable.

So, with 64MB or so, it's possbile to store fairly complete routing
tables for IPv4. The problem is the larger address blocks of IPv6.
(And also that some older routers can't use so many simms. This is not
really a problem for most Linux systems tho.)
