About the use of reverse DNS from webdnstools.com : Many things use reverse DNS. An example is anti-spam email software.

From Version Control with Subversion, Chapter 4. Branching and Merging In Subversion, a global revision number N names a tree in the repository: it's the way the repository looked after the N th commit. It's also the name of an implicit changeset: if you compare tree N with tree N-1 , you can derive the exact patch that was committed. For this reason, it's easy to think of revision N as not just a tree, but a changeset as well. If you use an issue tracker to manage bugs, you can use the revision numbers to refer to particular patches that fix bugs—for example, “this issue was fixed by r9238.” Somebody can then run svn log -r 9238 to read about the exact changeset that...
