I looked into this earlier today - the DD-WRT firmware for the hackable
routers is not vulnerable by default, because it is not configured to be a caching
nameserver, it only forwards. If your router actually caches, it probably
is vulnerable. Most important is upgrading any DNS servers, then your
clients. OpenDNS servers are already fixed, so if your ISP's servers have
not been patched yet, you may want to use OpenDNS for the time being.
