This article on django seems to give a clue

00.00.00.00 could be the internal rewrite ip address in which case then something is rewriting in a .htaccess to "none" which people frequently think apache can understand like

allow from none

where none is incorrect as apache then does a hostname lookup and gets nothing back.

That's a relevant guess btw.
