AFAIK normalized IP only differ from IP octet in decimal, in that each octet is 3 digit long.
192.32.1.12 is converted to 192.032.001.012 ..

:) Hope I could help.

A normalized IP is an IP address in Network Standard Byte Order, meaning (quote):
Version 4 of the Internet Protocol standard ("IPv4") specifies that numerical network addresses in an IP network ("IP addresses") are unsigned 32-bit integers, made up of 4 8-bit bytes that are transmitted in order from the most significant byte to the least significant byte. This ordering is called "network standard byte order."
Networked computer systems that use byte ordering schemes other than Big Endian generally have functions for converting between Big Endian network standard byte order and their internal order, called "host order."
 For example, on a computer system using Little Endian byte ordering, the Unix function ntohl( ) converts the value ... in Big Endian network standard byte order to the representation ...  in Little Endian host order.
