AAAA queries (was: Realtek 8139 (rl) very poor performance)

Thanks for your answer. I followed your advice, and that are the facts:

Using "dig hostname @my-isp-dnsserver A" seems to work pretty fine. However, 
if I type: "dig hostname @my-isp-dnsserver AAAA" sometimes miss (timeout) 
and, when it works, I get different results (no ip address, only pointer to 
an authoritative DNS server).

I've also done some tests using lynx (ipv6) and links (only ipv4). When I use 
links, it always works: it performs and "A" query and gets a result back. 
Then, the HTTP conversation starts.

However, using lynx, it performs first of all an AAAA query. When it works 
(not always do), I get a response but no IP address into that response. Then, 
sometimes it tries again with an A query, and then works. However, timeouts 
are killin' my patience :/

I've tested this issue with two different name servers. Could I confirm that 
is a DNS server's fault? Is my fault? Does exist any workaround about it?

Thank you.
