No, it's not; the issue is that the domains prefetch REGARDLESS of whether the links are ever clicked on. The browser is pre-fetching in case the user DOES click on the link. This really verges on being a browser bug, esp. since in firefox's case, it fetches both A and AAAA records.

The benefit is reaped in the event a link is actually clicked on. That's why browsers do it.
