If the answer to a query is larger than 512B, it is truncated and the client has to repeat the query via TCP to get the full answer. If you can absolutely *guarantee* that you will never ever generate answers that big, your DNS server doesn't have to support TCP. Keep in mind that if your server supports recursive queries, you have no control over the size of the answers!
