Some caches, like dnscache (and thus OpenDNS), may not respond to non-recursive queries. Would this break your dns_peek function?

- ryan-c 13y agoCorrect, it requires the cache to respond to queries with the recursion bit disabled. It will also probably behave in "interesting" ways when run against a resolver that's on an anycast IP and doesn't synchronize.
