The Internet Storm Center and DShield websites are about 25 years old. Back in the day, I made some questionable decisions that I have never quite cleaned up later. One of these decisions was to use a "15 character 0-padded" format for IP addresses. This format padded each byte in the IP address with leading 0's, ensuring that they were all 15 characters long (including the '.').
The end of an era: Properly formated IP addresses in all of our data., (Sun, Aug 24th)
