An anecdote here ... I crunched a day's worth of DNS traffic originated at ICSI (which is pretty much a "small resolver instance") from mid-Oct (which just happened to be handy). The entire root zone file would be ~725 full-size TCP packets. Our two main DNS resolvers together sent nearly 63K queries to the root nameservers. I am not arguing either of these is onerous for us. But, the notion that snarfing a MB of zone file is somehow a considerable increase in traffic vs. what we impose on the roots now seems dubious. allman _______________________________________________ dns-operations mailing list [email protected] https://lists.dns-oarc.net/mailman/listinfo/dns-operations
