There has been a very interesting discussion happening on the North American Network Operators Group (NANOG) mailling list about the scalability of today's Internet routers. A vast quantity of those routers support only 256,000 unique networks. According to the CIDR-Report, there are ~233,216 routes on the Internet, and at the current rate of 3,500 additional routes per month, we are going to be bumping into those hardware limits very quickly. Not many people are aware of the situation, and even fewer are prepared to perform the expensive upgrades. Has anybody already dealt with this and have solutions?
