You can use whatever numbers you want in your versioning - who's going to constrain you?
If you want your first version to be 0.0.0.0.0.0.0.1, that's fine, albeit a little silly. If you want your first version to be 106.3, you can do that too, but that's a little more ridiculous.
Check out the Wikipedia article on Software Versioning for some tried-and-true ideas of realistic version numbering schemes.
