But right now how should we be doing it?
Once you get the ASN or at least the domain name of the ISP providing service to the reflecting host, several major reputable ISPs (including my employer, who I can't name because I'm not an official spokesperson) will welcome RFC 5070 "IODEF" reports for general network abuse and RFC 5965 "MARF" format for email abuse, directed to abuse@ the main domain for that ISP.
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.
