Some highlights

Caches reachable within 6 IP hops and 20 ms
-IP path lengths shorter by 40–50%
-Latency lower by 64%
-Throughput higher by factor of three
-Latency benefits more pronounced over IPv4 compared with IPv6

Latency and IP path lengths similar between both address families
⇒ High IPv6 preference, however, slight drops during peak hours
