Hi I've noticed a strange effect in my bind logs, which appears to be certain applications tacking the search list onto a FQDN and doing a simultaneous AAAA query on this and the correct address. Same effect on three different Debian Etch machines. I'm running Bind9 on a small local network, forwarding external queries (although not sure if that's relevant at this stage).
/etc/resolv.conf: search mydomain.co.uk nameserver 192.168.1.30 $ssh machine.mydomain.co.uk results in four queries: machine.mydomain.co.uk.mydomain.co.uk IN AAAA + machine.mydomain.co.uk IN AAAA + machine.mydomain.co.uk IN A + machine.mydomain.co.uk IN A + Exim doing something similar: smtp.mailservice.co.uk.mydomain.co.uk IN AAAA + smtp.mailservice.co.uk IN AAAA + With my limited understanding, although this is likely harmless (man in the middle?), it shouldn't be happenning with no ndots spec change, and it's related to IPv6. Other info: $lsmod |grep -i ipv6 ipv6 226272 58 Changing search to domain makes no difference. Any help much appreciated.
