Tangential issue...

How are IPv6 addresses assigned to proxy4[-2] ?

If they are statically set on the machine, all good.

If they are assigned via radvd or DHCPv6, you might want to consider 
some setup where the machine's IPv6 address is proactively pushed to the 
DNS servers.  One method is nsupdate + TSIG, which is pretty easy to set 
up on a fine-grained basis (ie. give a DNS key DNS update perms for 
_only_ the proxy4 AAAA addresses).

Otherwise, the dynamically-assigned IPv6 address on the host may not 
match the IPv6 address in DNS.
