Subject: PATCH: dig warn user when querying ANY towards recursive server
Hi,
As recently came up, when querying a recursive caching server for ANY
will only result on cached entries being returned, and not the whole
possible set. For that you need to query the authoritative server.
I wasn't aware of this, and since I'm sure I'll forget about this again
too, I wrote a patch for dig to remind me. Please apply :)
Paul
