seems there is a ipv6 slowdown with comcast's dns servers. if you use firefox
you can stop ipv6 lookups by opening a tab in firefox and typing:

about:config

type:
network.dns.disableIPv6;false
set it to true and your dns lookups will take off.

if you use ssh, create an alias for ssh that looks like: alias
ssh='ssh -4' in your
.bash_profile, this will force using only ipv4 dns lookups. I don't
like passing on these workarounds because you may forget what you did
when the it is fixed, but maybe log it somewhere so you can undo when
this is fixed.
