Q:

What is the name of the default D&D 4E world containing the Nentir Vale?

The 4E Essentials rules compendium describes the Nentir Vale as a region of the Dungeons and Dragons world, but it does not mention the name of the world.  Does it have a name?

It doesn't have one. It's just "the Points of Light setting".
