Slow Mac DNS lookup fixed
Okay, it turns out Comcast was at fault after all. While the signal to the cable modem was good, apparently Comcast DNS servers no longer play nice with OS X Leopard, resulting in my hideous lookup delays. After turning off IPv6 (no effect) and manually configuring my Ethernet connection to use Open DNS Servers 18.104.22.168 and 22.214.171.124 (that was the ticket!) in System Preferences->Network, everything was back to normal, sites like nba.com, Google, mlb.com et. al were all working fine. It looks like when Apple went up to Leopard they changed the nature of their DNS queries to match the new standard, while Comcast's backwards DNS servers are still in old school mode. Thank you Open DNS servers and all the people on the internet who suggested to change to them.
