Internet Central DNS Server Settings

What DNS server settings should I be using?

IC provides recursive or caching name servers for you to use.

You can use these from any IC supplied connection. (They are for IC customers only, not the world to use)

To manage you DNS domains see this article How Do I Manage my Domains (DNS) ? 

For more information on DNS see wikipedia as it has detailed descriptions.
