hi,
whith any browser i use (mozilla, galeon, etc), the resolver always try AAAA (ipv6 request) as below when i type www.gentoo.org (tcpdumplogs ) :
15:03:44.240740 IP 192.168.1.4.33345 > maridia.nerim.net.domain: 45213+ AAAA? www.gentoo.org. (32)
15:03:44.281210 IP maridia.nerim.net.domain > 192.168.1.4.33345: 45213 0/1/0 (94)
15:03:44.281415 IP 192.168.1.4.33345 > maridia.nerim.net.domain: 45214+ AAAA? www.gentoo.org. (32)

15:03:44.366582 IP 192.168.1.4.33345 > maridia.nerim.net.domain: 33134+ PTR? 164.31.112.203.in-addr.arpa. (45)
15:03:44.408736 IP maridia.nerim.net.domain > 192.168.1.4.33345: 33134 NXDomain 0/1/0 (106)

15:03:44.453890 IP 192.168.1.4.33345 > maridia.nerim.net.domain: 33136+ AAAA? www.gentoo.org. (32)
15:03:44.493787 IP maridia.nerim.net.domain > 192.168.1.4.33345: 33136 0/1/0 (94)
15:03:44.494125 IP 192.168.1.4.33345 > maridia.nerim.net.domain: 33137+ PTR? 235.211.63.198.in-addr.arpa. (45)

when from a shell window i type ping www.gentoo.org i got the normal
dns request (A) :

15:06:31.001709 IP 192.168.1.4.33347 > maridia.nerim.net.domain: 33140+ A? www.gentoo.org. (32)

15:06:31.039912 IP maridia.nerim.net.domain > 192.168.1.4.33347: 33140 3/2/2 A mail.gentoo.org, A 203.112.31.164, A 198.63.211.235 (164)
15:06:31.049846 IP maridia.nerim.net.domain > 192.168.1.4.33348: 58531 NXDomain 0/1/0 (119)

Is there a way to prevent the browser of doing AAAA requests ? as it adds
enerving latencies
many thanks

I thought you had compiled mozilla with IPv6 support, but you haven't. Which means the only culprit can be the kernel. Compile your kernel without IPv6 support, that should fix things. (I assume you don't need IPv6 support - if you do, you can try compiling it as a module and not into the kernel).
Also check your /etc/resolv.conf - maybe your DNS servers are specified incorrectly.
Edit: Also see this Mozilla bug report

i'm using 2.4.25 and looking at the .config no ipv6 is enabled,
if it was the case i would have the same AAAA requests when doing ping www.gentoo.org
maybe i should install my own resolver ?

hi ,
i solved it , you were right it was IPV6 loaded in the kernel that was the culprit.
many thanks
