You don’t have to use your ISP’s DNS servers and sometimes can get better results with others. Try these:
8.8.8.8 8.8.4.4,
OpenDNS
Now part of the Cisco empire, the primary is 208.67.220.220 with a backup on 208.67.222.222.
Norton ConnectSafe
Available in its basic form on 199.85.126.10 (backup 199.85.127.10)
Comodo Secure DNS
Rather like Google in that there is no configuration – using the service is simply a matter of switching to the services primary and backup servers on 8.26.56.26 and 8.20.247.20.
DNS.Watch
Available on 84.200.69.80 and 84.200.70.40, DNS.Watch is almost unique in offering an alternative DNS service without the website logging found on most others.
VeriSign Public DNS
Not to be outdone, VeriSign recently started offering public servers on 64.6.64.6 and 64.6.65.6.
