<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#002060"> I strongly suggest that you consider other methods to accomplish what you’re trying to achieve. You seem to have latched onto one particular
method to reach your goal – modifying the contents of the DNS request and/or response packets – but this amounts to changing the DNS protocol. There is no BIND configuration “tweak” to accomplish it – you’d have to hack on code (probably the code for both
the client and server sides). This is a significant undertaking, and if you’ve never hacked on BIND code before, prepare yourself for a steep learning curve.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#002060">If all you’re trying to do – as someone surmised in another post – is control client access to resources, then it should be possible to leverage existing non-DNS
technologies and resources for this (firewalls, proxies, etc. configured with appropriate ACLs), or, as also suggested, RPZ. Why reinvent the wheel?<o:p></o:p></span></p>
