ISP still blocking sites after changing DNS.

Specs: Windows XP, 4GB
My ISP has its own DNS nameservers. As my ISP is blocking some sites, I decided to change the DNS nameservers to OpenDNS.

After changing the DNS nameservers to OpenDNS, I noticed that my ISP is still able to block those sites.

My question is how does my ISP know I am connecting to those blocked sites since I'm not using its nameservers anymore?

Is it because my ISP knows my IP address and since I'm using its internet connection, it is able to block? I don't think I'm correct in this deduction because when I use a free proxy, I'm able to connect to those blocked sites.

Anybody knows what exactly is happening here?

i think its because all the data goes through your isp's server when you dont use proxy.and which sites are you going to there might be viruses in them the isp wouldnt block them for no reason

Can you explain to me how my ISP knows I'm visiting a certain site even though I'm not using the ISP's Nameservers?

At which point in the transmission did my ISP intercept my traffic? And how come when I'm using a proxy, my ISP does not know which site I'm visiting?

When data travels over the internet each packet of data contains both a source and destination IP address. Firewalls use this information and it allows an ISP to block access to specific addresses. When you go through a proxy the only addresses that your ISP can see are yours and that belonging to the proxy.
