EDIT: Per a comment I realized I left alot of stuff out. Here ya go:
I am scanning everything from 188.8.131.52 to 184.108.40.206.
I am collecting hostname, IP address, OS type, and service version.
I was way off on this, Its Almost a year later and we are still running.
I am aware Shodan offers this information now, I need to collect my own data for this project however.
EDIT: This isn't a big deal. Researchers like us frequently scan the IPv4 address space. At any point in time, there are a few "white-hat" researchers doing such scans (we know of one other group currently conducting a scan), and many more "black-hats" doing it. The reason for this post is simply to be on record about it.
EDIT: We have added a new IP Address we are scanning from: 220.127.116.11. This is a followup machine that takes the oldest entries in our databases and checks if they are still alove/resemble what we collected.
