I've seen this recently on one site. It's some kind of attack--I don't
know what exactly it's trying to exploit, or whether it's just meant
as a DNS attempt. In the case I saw, we were alerted by a sudden spike
in bandwidth usage.

TYPO3-wise, I'd double-check that all your extensions are up-to-date,
and after that, I'd see about blocking the requests at the source--we
had thousands of these requests and it ate up a lot of bandwidth.
