The reason is that squid is requesting AAAA records, and the broken DNS server (a load balancer, probably) is responding with NXDOMAIN instead of NOERROR. Maybe there's a configuration option in squid that tells it not to try to use IPv6, so it won't request AAAA records. -- Barry Margolin Arlington, MA _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
