Well, I guess it should work, assuming you let it deal with separate
files/directories and don't mix too much between the two instances.
But - why would you prefer to do 2 separate instances, instead of just
having 1 listening on both IPv4 and IPv6? Just run it without any "-4" or
"-6" options, and tell it to listen to your IPv6-address(es) as well, with
adding something like this to your options block in named.conf:
listen-on-v6 { any; };
I see you mention you run ISC DHCP 4.1 of some version: yes, the DHCP
software can currently only run either IPv4 or IPv6. BIND can easily deal
with both protocols at the same time.
