I followed your advice, and that are the facts: Using "dig hostname @my-isp-dnsserver A" seems to work pretty fine. However= ,=20 if I type: "dig hostname @my-isp-dnsserver AAAA" sometimes miss (timeout)=20 and, when it works, I get different results (no ip address, only pointer to= =20 an authoritative DNS server). I've also done some tests using lynx (ipv6) and links (only ipv4). When I u= se=20 links, it always works: it performs and "A" query and gets a result back.=20 Then, the HTTP conversation starts. However, using lynx, it performs first of all an AAAA query. When it works= =20 (not always do), I get a response but no IP address into that response. The= n,=20 sometimes it tries again with an A query, and then works. However, timeouts= =20 are killin' my patience :/ I've tested this issue with two different name servers. Could I confirm tha= t=20 is a DNS server's fault? Is my fault? Does exist any workaround about it? Thank you. =2D-=20 Imobach Gonz=E1lez Sosa imobachgs en banot punto net osoh en jabber.org
