That's how you write a fully-qualified domain. Domains of the form "example.com" are not actually fully qualified. They're relatively qualified, but "to save typing" (actual quote from RFC 1034) we make that relative qualification to the root zone. Now, the thing is that the root label is 0 octets long (that's how you know it's the root), so it can't be typed. So, you end up with a separator and no visible label after it when the labels appear in presentation form (like in running text).
