Tony, Here the information concerning converting to IP address to a number string: With some firewall implementations, you can bypass the URL filtering rules: Obtain IP address of a filtered URL: http://www.netaddress.com or http://204.68.24.100 Convert IP address to binary using calc.exe - 11001100 01000100 00011000 01100100 Concatenate the binary together 11001100010001000001100001100100 Convert this number to decimal using calc.exe - 3427014756 Enter this in your browser - http://3427014756 John Bumgarner, CISSP -----Original Message----- From: Tony King [mailto:tonykingat_private] Sent: Thursday, April 26, 2001 08:20 To: PEN-TESTat_private Subject: Re: websence bypass ? You can sometimes add :80 to the end of a url http://www.yahoo.com:80 You can also use the ip address of the webserver http://xxx.xxx.xxx.xxx Maybe even add a :80 to the end of the ip url. There is also a way to convert the ip address into a number string, I have to go talk to some people to remember how to do that one, but email me back so that I remember.
