Sachin,
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.
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?

Subject: Re: Sending extra info in bind dns query packet
I have searched through the list and found discussion about standard practice
not to add it.
I did not find any post which gives clear idea on how to add the custom
additional section record in dns query packet.

This has been discussed several times on this list within the past few weeks.
You should check the archives.
