I thought recursive resolvers are geographically local enough for caching web services. I checked mine and it seems to be 4 hops away, 2 beyond our network perimeter.
\24 is very intrusive and what about those who are behind ISP NATs. \24 may not be as useful to Google.
- aristus 17y agoFor most people they are but you'd be surprised at how many basly-placed or -configured resolvers there are out there. Consider a nationwide ISP with resolvers on East coast and West coast. For "failover" they assign them in random order to customers. That means 50% of the time a customer of the ISP in Tampa will appear to be coming from a resolver in San Jose.
