What CIDR Range is reserved for Network interconnectivity device benchmark testing?


EXPLANATION

198.18.0.0/15 - This block has been allocated for use in benchmark tests of network interconnect devices. [RFC2544] explains that this range was assigned to minimize the chance of conflict in case a  testing device were to be accidentally connected to part of the Internet. Packets with source addresses from this range are not meant to be forwarded across the Internet. 


Special address blocks
Address block Address range Number of addresses Scope Description
