The Dynamic IP Restrictions Extension for IIS provides IT Professionals and Hosters a configurable module that helps mitigate or block Denial of Service Attacks or cracking of passwords through Brute-force by temporarily blocking Internet Protocol (IP) addresses of HTTP clients who follow a pattern that could be conducive to one of such attacks. This module can be configured such that the analysis and blocking could be done at the Web Server or the Web Site level.

I see this character in Firebug "."

The character in question "&#65279" is the Unicode Character 'ZERO WIDTH NO-BREAK SPACE' (U+FEFF). It may be that you copied it into your code via a copy/paste without realizing it. The fact that it's not visible makes it hard to tell if you're using an editor that displays actual unicode characters.

Just use notepad ++ with encoding UTF-8 without BOM.

To find out other sites hosted on a web server by entering a domain or IP address above.
http://www.yougetsignal.com/tools/web-sites-on-web-server/

And another solution is to get ip address by ping and use bing and search "ip:148.251.23.00"
example
