(Following up on the last post about spam IPs) The Internet Assigned Numbers Authority (IANA) published an IP list showing the allocation of IP blocks. According to this, all IPs starting with:
- 5 and 95 are IANA reserved
- 6 are US Army
- 18 are MIT
That leaves 85 and 75 as possibly real IPs.

Previous discussions have identified that using a CAPTCHA may not be the best method of preventing spam comments while allowing accessibility. While the W3.org comments on the subject may have been valid a few years ago, even the most out of the way blog today risks being inundated with spam comments, which in turn can cripple how a blog is indexed.
Since the chance to WordPress 2.1 we have removed the CAPTCHA and although spam comments are still attempted it seems they are being held back.
Recently it has also become quite apparent that there are a limited number of IP addresses from which this spam is being generated. As a result, any IP address which generates more than four spam comments will be added to the black list and at irregular intervals we will identify the most recent additions here.
Today, 85 spam messages were generated by the following IP addresses:
Geographically speaking, there is not a lot of variation.
If you are the owner or administrator of one of the above domains, there is a good chance you have an open network which is being misused.
