AFAIK DNS is address translator, it won't help giving you an access to blocked website, especially if it blocked by your ISPfarayeth wrote:you can overcome this problem by using google DNS or openDNS. change your DNS via control panel.
GOOGLE DNS
preferred DNS : 8.8.8.8
alternate DNS : 8.8.4.4
OPEN DNS
preferred DNS : 208.67.222.222
alternate DNS : 208.67.220.220
you should try like hidemyass.com or anonymouse.org/anonwww.html instead to access blocked sites
or you can look/find for proxy (i am not guarantee it will work too)
the alternative way (maybe the best) is to find fast VPN
because your connection will always going and coming from VPN, instead blocked sites
