IPv4记录路由（RR）选项指示路由器在数据包中记录其IP地址。RR受限于9跳限制，并且传统上，来自路由器的支持不一致。域间连接的最新变化--所谓的“扁平化互联网”--以及路由器应如何处理RR数据包的新最佳实践表明，现在是重新评估RR选项潜力的好时机。我们通过从PlanetLab和M-Lab向每个广告的BGP前缀发布RR测量值来量化RR的当前效用。我们发现，75%的地址，响应ping没有RR也响应ping与RR，这些RR响应地址的66%是在9跳限制至少一个Vantage位置。这些数字表明，在今天的互联网上，RR选项是一个有用的衡量标准。
The IPv4 Record Route (RR) Option instructs routers to record their IP addresses in a packet. RR is subject to a nine hop limit and, traditionally, inconsistent support from routers. Recent changes in interdomain connectivity---the so-called "flattening Internet"---and new best practices for how routers should handle RR packets suggest that now is a good time to reassess the potential of the RR Option. We quantify the current utility of RR by issuing RR measurements from PlanetLab and M-Lab to every advertised BGP prefix. We find that 75% of addresses that respond to ping without RR also respond to ping with RR, and 66% of these RR-responsive addresses are within the nine hop limit of at least one vantage point. These numbers suggest the RR Option is a useful measurement primitive on today's Internet.
