If we had "clean" registries and signed/verifiable advertisements this would not be an issue. Most of you know that DHS was pushing the Secure Protocols for the Routing Infrastructure initiative (http://www.cyber.st.dhs.gov/spri.html). Due to budget cuts this program is on the shelf for now. However, we are still interested in making it happen. I think that the discussion about 7.0.0.0/24 several days ago could also have been avoided if we had already implemented some of the SPRI ideas.

ISP in Canada. We have IP block 99.x.x.x assigned to our customers. Which happened to be bogons block in the past and was given to ARIN in Oct 2006. As we have recently started using this block, we are getting complains from our customers who are unable to surf some web site. After investigation we found that there are still some prefix lists/acls blocks this IP block. We own the following blocks: 99.224.0.0/12 99.240.0.0/13 99.248.0.0/14 99.252.0.0/16 99.253.128.0/19 Please update your bogons list. Shai. end
