<p>It is not entirely clear from your question, so it may be that your question applies to NSD vs BIND rather than Unbound vs BIND. Note where BIND is a combined recursive server and authoritative server, Unbound is a standalone recursive server, and NSD is
a standalone authoritative server.<br>
</p>
If your hosting provider is handling the authoritative DNS, then you can use Unbound and python plug-ins to modify the records. You may find a reasonable starting point under "examples" here:

http://unbound.net/documentation/pythonmod/index.html</a>. Maybe do something similar to blacklist record manipulation and instead strip excess records.<br>
