We are all aware of the growth in routing complexity, and the rapid increase in allocation of network numbers. Given the rate at which this growth is being observed, we expect to run out in a few short years.
If the inter-domain routing protocol supports carrying network routes with associated masks, all of the major concerns demonstrated in this paper would be eliminated.
One of the influential factors which permits maximal exploitation of the advantages of this plan is the number of people who agree to use it.
If service providers start charging networks for advertising network numbers, this would be a very great incentive to share the address space, and hence the associated costs of advertising routes to service providers.
