The Domain Name System is a distributed database that maps names to computers' IP addresses. It's one of the cornerstones of the Internet.

Because it is so important, there are many standard ways of working with it. Some people, for example, may want to cache their DNS results if they have a slow connection to the Internet, or to their DNS server in particular. Linux, for example, provides caching hooks right in the GNU C library. Windows also provides DNS caching.

I wanted to give you all anonymous access to my public git repositories, and I wanted to add a special field in my Drupal "Blog Post" content type to allow it.  (Results can be seen in my post about dbgp).  It was all pretty standard.  I added a field to my content type.  The field was of type "Link", as provided by the Drupal Link module.
