How to get a list of all attachements urls for every post of a wordpress installation?

I'd like to retrieve a list of all attachment URLs for all posts of a website.

This would bring something like
http://example.com/mypost/attachment-1/
http://example.com/mypost/attachment-2/
http://example.com/anotherpost/attachment-deff/
http://example.com/post3/attachment-deff4/

Would it imply to use: wp_get_attachment_url
