ehi , I've tried the last version of Mozilla (1.4)
installed via Ports updated with CVSUP , and It works
perfectly with INET6 enabled . I think that mozilla
team have solved ;)

 I see quite a few  lookups, but no responses. 
 It seems to be a
 problem with the nameservers you are using:
 
 Compare this  lookup against 80.20.6.36:
 
 happy-idiot-talk:~:% dig @80.20.6.36

 With this A lookup:

 Note that the nameserver of 212.216.112.112 responds
 correctly:

 Recommendations: 1) Complaint to your ISP or whoever
 it is that
 provides you nameservice via 80.20.6.36 (which looks
 like somebodies'
 home machine: host36-6.pool8020.interbusiness.it)
 Ask them if they can
 provide a standards compliant nameservice.
 
 2) Reorder the nameserver lines in /etc/resolv.conf
 so that:
 
 nameserver 212.216.112.112
 
 appears before
 
 nameserver 80.20.6.36

Sounds like a classic case of misconfigured DNS.  Double check your
/etc/resolv.conf -- it's quite likely that the first nameserver entry
is incorrect.  Maybe more than one is incorrect, given how long it
takes to come up with an answer.

Alternately, it might be a problem to do with IPv6 DNS lookups.
Mozilla does these by default (as properly configured applications are
meant to do now-a-days).  However, and despite the fact that the RFCs
defining the  resource record were published nearly 10 years ago,
there are any number of broken DNS servers out there which simply
*won't reply* to an  request.  The resolver on your system can do
nothing except wait until the request times out, which takes several
minutes.  Note: in this case it isn't Google's nameservers, as they
return practically instantaneously with the correct response that
there isn't a  address for www.google.com.  Similarly for Yahoo.
Many purveyors of advertising however seem to use broken nameservers,
and that can consequently block loading of many web pages.

Seeing as it's Mozilla you're using, just blocking images from the
offending servers will enhance your web browsing experience.
Unfortunately, about the only sure way to be sure of never running
into this is to recompile your system without IPv6 support in the
kernel.

Cheers,

Matthew

Ehi, u were right!!

I've disablited INET6 support in the kernel and now
Mozilla works perfectly!!!

But, what are the disadvantages? What I have
lost?FreeBSD 5.1 have this problem too , and this
is a problem or whatever else?
Thanks

You won't be able to use IPv6. Unless you know what this is,
you don't need it.

(If you do know what it is, and you want a /64, one good site
is ipv6.he.net).

I know what IPv6 is (generally) , but I think I'll
don't need that for normal Internet use. I've ever
used Linux before FreeBSD , and I've always disabled
IPv6 in the kernel, but enable it never gave any
problem . I've also tried in the past FreeBSD (5.0)
but I haven't found any problem. (the only difference
was that I've compiled all the system with ports and
now I've installed all by SYSINSTALL Packages
management). Why this difference?

Thanks

Re: Mozilla and long time in resolving Hostnames

Rebuild you kernel without IPV6. There is somewhere
between 3 and 4 references to IPV6 in the
configuration  file.  Just make sure they are
commented out and you will be good to go.

Happy surfing,
