In my case, it turned out to me a couple of things. The DNS UDP packets seem to be a bit longer now. I am currently connected to Verizon FIOS through an Actiontec cable modem/router, which some websites say truncates UDP packets to 512 bytes, in accordance with RFC negative 666. :-) That caused problems with hostica and others. I changed /etc/named.conf to a policy of forward first, and used the Verizon nameservers as forwarders, taking out the lookup through the root nameservers. Verizon does some goofy things with nonexistent URLs, but I can live with that for now.
