This has got nothing to do DNS, let alone the internals of one
implementation of the protocol(s). Neither the DNS nor BIND care what
the IP-layer packet hop count is/was on the queries they get.
You'd be better off asking in some IPv6 forum or somewhere specific to
the kernel of the OS you're using. It might be possible to tweak an
appropriate kernel configuration setting -- sysctl is your friend --
or hack the code and recompile.
However there are very good reasons for using low hop counts on
multicast packets. It's usually a VERY bad idea to tinker with them.
