[xwiki-users] Can't use IP as pagename, why?

Hello List, I wanted to edit a list with IP's and every listed IP is backlinked to a page with the IP as name. Wikicode-example (xwiki v1.2.2.7518): Page "Main": * [192.168.1.1]: Blabla * [192.168.1.2]: Blabla * [192.168.1.3]: Blabla Now i look at "Main" and i see following: 168.1.1: Blabla 168.1.2: Blabla 168.1.3: Blabla In HTML: <li><span class="wikilink"><a href="/xwiki/bin/view/192.168.1/1">168.1.1</a></span>:Blabla</li> <li><span class="wikilink"><a href="/xwiki/bin/view/192.168.1/2">168.1.2</a></span>:Blabla</li> <li><span class="wikilink"><a href="/xwiki/bin/view/192.168.1/3">168.1.3</a></span>:Blabla</li> The URL behind the links are now: http://localhost:8080/xwiki/bin/view/192.168.1/1 http://localhost:8080/xwiki/bin/view/192.168.1/2 http://localhost:8080/xwiki/bin/view/192.168.1/3 Instead of linking pages, the wiki did add a complete webspace called "192.168.1"?? And additionally, the "192." is gone??? How do i have to understand this behaviour? Kind regards, Florian
