問題文
An organization runs a translation service that keeps no per-flow state, so its internal nodes carry addresses that a version 4 node can reach and the outside version 4 nodes are represented by converted addresses. An engineer has to record what the two kinds of address gain from being built on one and the same prefix, and what the specification says about routing on a prefix longer than 64 bits. Which statement is correct?
