"If using the 10.0.0.0/8 address space for the fan is impractical, other possibilities exist. The IANA IPv4 Address Space Registry (http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xhtml) specifies /8 address space assignments. If you decide you don’t need to communicate with one of these network blocks, you can use it instead of the 10.0.0.0/8 block used in this document. For instance, you might be willing to give up access to Ford Motor Company (19.0.0.0/8) or Halliburton (34.0.0.0/8). The Future Use range (240.0.0.0/8 through 255.0.0.0/8) is a particularly good set of IP addresses you might use, because most routers won't route it; however, some OSes, such as Windows, won't use it." --------------------------- Liste de diffusion du FRnOG http://www.frnog.org/
