I'm getting the following errors in /var/log/daemon.log

Dec 31 15:15:25 demigod named[12914]: success resolving 'youtube-global.blogspot.com/AAAA' (in 'blogspot.com'?) after reducing the advertised EDNS UDP packet size to 512 octets

and sometimes:

Dec 31 14:43:23 demigod named[12478]: success resolving 'www.vg.no/A' (in 'vg.no'?) after disabling EDNS

I've disabled everything related to intrusion detection and firewall in the ADSL-router but still get these errors. Tried adding edns-udp-size 512; to /etc/bind/named.conf.options but it doesn't seem to have any effect. Any ideas? I also tried adding the adsl-router as a forwarder, this reduced the number of error messages slightly...

Any ideas???
