The root zones and most TLDs tend to have longer, non trendy (over 5 minute) TTLs, so root servers, TLDs and other auth servers get orders of magnitude less queries than large recursive farms, which cache and then get cache hits. Comcast & Google get 2-3 orders of magnitude more than large TLD servers and 4-5 orders of magnitude more than the root servers and these two probably represent something like 1/3 of public recursive server traffic. The largest Chinese ISP used to do more traffic then either of the above. But compared to a large corp DNS server farm, the root servers shovel a lot of bits. Some of it even valid DNS queries and responses. ;) _______________________________________________ dns-operations mailing list dns-operations@lists.dns-oarc.net https://lists.dns-oarc.net/mailman/listinfo/dns-operations
