As the IPv4 space get smaller and smaller, does anyone think we'll see a time when /25's will be accepted for global BGP prefix announcement. The current smallest size is a /24 and generally ok for most people, but the crunch gets tighter, routers continue to have more and more ram will it always be /24 the smallest size?
RAM != FIB.
For /24, cheap 16M entry SRAM == FIB
The forwarding hardware is generally going to be the limit, and that's going to be painful enough as we approach a half million prefixes.
True. And that's why we must avoid IPv6. Masataka Ohta
