It doesn't work. I tried: listen-on-v6 port 53 { ::3; }; listen-on port 53 { 127.0.0.3; }; and all combinations (also disabling ipv4 or ipv6). It works only if I explicitly add that ip address. 2017-10-05 14:33 GMT+02:00 Mark Andrews via RT : > > try listen-on-v6 > > -- > Mark Andrews, ISC > 1 Seymour St., Dundas Valley, NSW 2117, Australia > PHONE: +61 2 9871 4742 INTERNET: marka@isc.org > > >
