Thanks, the IP->subnet/ASN lookup and rfc5070 look like exactly what we need to start with. I'm fairly certain it would have gotten us the same contact for all the IPs we reported last week. Since IODEF is so flexible, are there any exact guidelines or examples on how to use it to report a DDOS? For example, should there be a separate XML document for each prefix or one for the entire list? What I found was https://tools.ietf.org/html/draft-ietf-mile-iodef-guidance-03#page-21 but it could use some more explanation.
