For an Internet Service Provider, AS numbers are a logical representation of the other ISP peering or communicating with his autonomous system. ISP customers are using the capacity of the Internet Service Provider to reach Internet services over other AS. Some of those communications can be malicious (e.g. due to malware activities on an end-user equipments) and hosted at specific AS location. In order to provide an improved security view on those AS numbers, a trust ranking scheme will be implemented based on existing dataset of compromised systems, malware C&C IP and existing datasets of the ISPs.
The problem is that the network 223/8 is defined in IPy as reserved but it is not the case anymore.
The trac of the project (http://software.inl.fr/trac/wiki/IPy) is buggy: it is not possible to create a new issue and I was not able to find a contact.
I will probably have to fork the project until it is fixed.
IPy is used to normalize the IPs but also to verify that the IPs are "correct" (not private or reserved) -> http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xml
