The option log-queries: yes logs the query name and IP address to the logs and does not have the debug overhead that verbosity 5 has. It does not log in more detail, something for which dnstap is good. For lightweight, just query names and IP addresses the log-queries option is an easy way to log it. local-zone type inform will also log the querier for a smaller, select, part of the namespace. Use this if you want to have even less log messages, only for specific names (and specific suffixes).
