Has someone a explanation for this? dig, by default, sends an EDNS bufsize with a request (4096 bytes in the version I tested), allowing the server to go beyond 512 bytes. If you add +noedns or +bufsize=512, you should see a truncated answer (although, if additionals are the reason, the TC-flag will not be set). HOWEVER, if the packet cache is enabled, and the query that caused a packet cache entry happened to have EDNS, non-EDNS clients coming in after that will also get the big answer. I will write a ticket about this.
