What is a Crazy IP?

A Crazy IP is an IP address that’s in the pure numerical format rather than the regular ‘dotted quad’ format. For instance, BBC News’ IP address is 212.58.226.30 in the dotted-quad notation. Based on this, its Crazy IP address is 3560628766.

What use is a Crazy IP?

Crazy IPs can often be used in place of a regular IP address. You can ‘ping’ them, FTP to them, and (if your browser doesn’t block them) browse to them. (Note - these no longer seem to work in Internet Explorer.)

Because of this ability to mask the server address, some dodgy spam and porn sites use this as a way of hiding the real domain serving a URL.
