Most people cite the following benefits of using OpenDNS:

a) web-content filtering protection
b) improved speed of name-resolution

I think a) above can be achieved without using OpenDNS - if you have a router, it most probably provides ability to do URL filtering and if you use a firewall, depending upon what its capabilities are, you can be protected against unwanted web-content and can implement URL filtering too, in addition to IP-address based filtering. Depending upon what browser and software you use, you can be further protected. The facility provided by OpenDNS does not weigh favourably against the compromise in privacy.

And I wonder how well OpenDNS would work to provide this protection if DNS resolution is not involved at all (directly accessing a server by IP address). Its web-content filtering etc. will not work then, correct? But if you used other mechanisms to protect yourself, they may still work. Of course, the other mechanisms can be used in addition to using OpenDNS.

b) is largely immaterial because DNS queries are mostly cached, so it is only the initial hit which is slow (and not that terribly slow) in case of people not using OpenDNS.

However, on certain days and in certain places and configurations, it is useful to have OpenDNS as a fallback DNS server.

Whenever you type a domain name like www.indiabroadband.net in a browser, this name must be converted to an IP address.. then only the browser can establish the TCP connection with the web server running on that IP address..
To convert that domain name to a corrosponding IP address, computer make use of DNS servers.
