Single Number Network Address

IP address can be written as a single hexadecimal number. For example, www.yahoo.com.hk is 202.43.221.34, it is written as :

202x 256x256x256+43x256x256+221x256+34=3391872290

http://3391872290 will exactly go to the same website.

Increasingly, fraudsters are using single number network address to hide the source of phishing sites.
