If the sites are CLOSED changing the DNS address won't help you.
The Domain Name System is what translates domain NAMES, aka www.******.com to IP addresses, which your internet can access, aka http://74.125.224.72/.
The solutiion you're offering is changing the DNS server address, which can help in case your automatically assigned DNS server is down and you have to manually configure one, like ******'s DNS servers (8.8.8.8 or 8.8.8.4).
