    Sean> 1) Is there a doc somewhere that describes how to do IPv6 addresses in bind

  Yes, it is in the bind Admin Reference Manual. Look in /usr/pkg/share/doc/bind9
(You'll want to run bind9 if you want bind to answer on V6 sockets) I'm not
sure that we ship ARM with the default system.

    Sean> 2) How do I determine what the IPv6 address for each machine should be

  Well, each interface can have multiple addresses. 
  1) a link local address which is fe80::EUI64 (derived from MAC address).
  2) addresses that you configure like IPv4.
  3) addresses that you get by neighbour discovery from your IPv6 capable
     router.

  Since you probably do not have #3 and #2 is more useful if you have your
own address space assigned, you probably want to look at 
    4) a 6to4 address. See http://www.kfu.com/~nsayer/6to4/
			   http://www.daemonnews.org/200101/6to4.html

  Basically, you get 2002:ABCD:EFGH::/48 where AB.CD.EF.GH is your IP address.

  I use the following on my notebook (called from dhclient-exit-hooks) to
make sure that I always have IPv6, so long as there is no NAT.

#!/bin/sh

PATH=/usr/sbin:/sbin:$PATH export PATH
myip=$1

# Now configure my stf driver.
set -- `echo $myip | sed -e 's/\./ /g'`
A=$1
B=$2
C=$3
D=$4

if [ $A = 10 ]
then	
	exit
fi

if [ $A = 172 ] && [ $B '>=' 16 '|' $B '<=' 31 ]
then
	exit
fi

if [ $A = 192 ] && [ $B = 168 ]
then
	exit
fi

v6to4addr=`printf '2002:%02x%02x:%02x%02x' $A $B $C $D`

# remove any other addresses
#stf0: flags=1<UP> mtu 1280
#	inet6 2002:d11f:72ca::20 prefixlen 16
#	inet6 2002:d11f:71c2::20 prefixlen 16
ifconfig stf0 | while read first second third 
do
	case $first in
	inet6) ifconfig stf0 inet6 $second delete;;
	esac
done

ifconfig stf0 inet6 $v6to4addr::20 prefixlen 16 alias up

if netstat -rn -f inet6 | grep '^::/0' >/dev/null
then
	echo Already got default IPv6 route
else
	# gateway6.sandelman.ottawa.on.ca
	route add -net -inet6 :: 2002:c08b:2e21:3::1
fi
