I've just updated to tw0.31 and everything works fine, BUT in the latest visitors view I got some strange IPs. Usually I would expect them to be in a form like this: xxx.xxx.xxx.xxx. Actually I see a lot of them appearing this style: "NS (!NS 7-3716542179)". Browsing through the latest visitors I can see a few hundred normal IPs followed by a few hundred of these strange IPs. Also the page report is filled with "!NS"-numbers instead of expected html-files.
Attached you can find a little screen shot of this issue.
As I do not know how to interpret these "!NS"-numbers, may be someone here can give me a little hint?!
Many thanks in advance!
