A dotless IP address
is a standard xxx.xxx.xxx.xxx IP address represented as either a decimal DWORD
, or octal
internet browsers, such as Microsoft Internet Explorer
, are able to decode such addresses to their correct IP's. In MSIE 4.x, there was a security vulnerability that would make any dotless IP address apear as if it was on the user's intranet
, which was set to the lowest level of security protection within the browser.
An example of this is as follows:
E2's address is http://www.everything2.com . Its IP address is http://18.104.22.168 . Its dotless IP address in DWORD is http://3467251331 . All three addresses take you to the same place.
