Re: Earthlink's broken DNS affecting Tor nodes?
yes, it is a bad thing. the easiest thing to do (if you are running
tor on a unix box) is to install BIND 9 as a caching nameserver, and
configure your resolver library to use BIND instead of your ISP's
nameservers (man resolv.conf).
Most modern unix distributions come with BIND 9, and just require
you to enable them somewhere like /etc/rc or /etc/sysconfig.
Anyone running tor should consider doing this, as you'll be making
name resolution almost an order of magnitude faster; in addition to
not having to trust nameservers configured to lie by a marketing
If you're running Windows; well, good luck.

Should I be concerned about this change's effect on the Tor network, since
presumably DNS lookups I do are no longer perfect? If it does have a
detrimental effect, is there a way to block DNS lookups in my exit policy?
