It could be the problem with some nameservers never answering queries for IPv6 records (aaaa). mozilla (and therefore phoenix I would guess) try to look up IPv6 adresses of hosts if the OS has IPv6 support. I don't know how to fix it but workarounds are to remove INET6 from your kernel or using a proxy server (which then does the resolving IPv4 only). You can reproduce the problem with the hosts program... : $ host -t a ad.doubleclick.net works ok, but=20 $ host -t aaaa ad.doubleclick.net just hangs. > While it's trying to resolve ad.doubleclick.net, phoenix is unable to > resolve anything else, even sites it can normally resolve immediately. > Konqueror has no such problem -- it can resolve something else while > waiting on ad.doubleclick.net. It think that is due to the way mozilla/phoenix handles DNS which is not very good when a DNS server does not respond. > cache locally (djbdns) doesn't help either.
