HI,

my PDNS currently do IPv4 recursion with the following config:

recursor=8.8.8.8


How can i add an IPV6 Recorder to the pdns.conf ?


This is what I use in my pdns.conf:

    local-address=127.0.0.1 10.10.10.10
    do-ipv6-additional-processing=yes
    local-ipv6=::1 2001:xxxx:xxxx:xxxx::xxxx
    local-port=53
    allow-axfr-ips=10.10.10.10, 10.10.11.10
    recursor=127.0.0.1:5300

And in recursor.conf (hosted on the same box):

    local-address=127.0.0.1,10.10.10.10,[::1],[2001:xxxx:xxxx:xxxx::xxxx]
    allow-from=0.0.0.0/0,::/0
    query-local-address6=2001:xxxx:xxxx:xxxx::xxxx
    local-port=5300
    aaaa-additional-processing=on

10.10.10.10 is the IPv4 address of the box (it is public, and I have replaced it).
2001:xxxx:xxxx:xxxx::xxxx is always my IPv6 address of the box (public too).

I can't tell whether this is the best configuration (I welcome all comments), but it works.

As Maik has said, in fact we communicate with the recursor over local IPv4 (at a different port). It is true that it's better to have a different box for auth and recursion, but we have a low volume of DNS queries and it's not a problem at this time.

Hope that helps.

Nick
