论文摘要
我们考虑发现IPv6网络外围设备的问题，即在IPv6 Internet中连接Endhosts的最后一个跳路由器。由于IPv6地址空间大小，各种各样的提供商地址和子网格方案以及不完整的拓扑痕迹，因此使用主动探测找到IPv6外围是具有挑战性的。因此，现有的拓扑映射系统可能会错过IPv6外围的大量占地面积，从IPv6人口普查研究到地理位置和网络弹性的不利应用程序。我们介绍了“前卫”，一种明确发现IPv6网络外围的方法，并使用它来查找> 〜64m ipv6 IPv6外围路由器路由器地址，> 〜87m链接到这些最后的啤酒花 - 比当前可用的IPV6拓扑多几个数量级。此外，现有的IPv6列表中，只有0.2％的Edgy发现的地址已知。
We consider the problem of discovering the IPv6 network periphery, i.e., the last hop router connecting endhosts in the IPv6 Internet. Finding the IPv6 periphery using active probing is challenging due to the IPv6 address space size, wide variety of provider addressing and subnetting schemes, and incomplete topology traces. As such, existing topology mapping systems can miss the large footprint of the IPv6 periphery, disadvantaging applications ranging from IPv6 census studies to geolocation and network resilience. We introduce "edgy," an approach to explicitly discover the IPv6 network periphery, and use it to find >~64M IPv6 periphery router addresses and >~87M links to these last hops -- several orders of magnitude more than in currently available IPv6 topologies. Further, only 0.2% of edgy's discovered addresses are known to existing IPv6 hitlists.
