As for the average number of hops, it clearly depends on what type of traffic and many ASNs have more than one router. Going on my own experience I would say between 8 and 10 hops would be the average of non-cached content. If you included cached content such as cdns and caches then the actual average might be closer to 5 to 7. This is only an estimate from my own network and those of my clients so the actual value may be completely different.<div class=""><br class=""></div><div class="">As with what others have said, I’m not sure on what use this data, if collected, would be.
