There has been no discussion on the GROW mailing list about having this document published as Standards Track rather than informational and it's coming as a surprise to see that this was only announced at IESG Last Call a couple of days ago. At the least, there ought to be some discussion about this before pushing it up into the publication queue. Personally - and I say this as an IXP operator who has had yet another week-end ruined due to prolonged DDoS problems on an IXP fabric - I don't think this is an appropriate document for standards track, or even for publication as an RFC. The reason for this is that section 3.4 creates the expectation that IXPs could or should be involved in facilitating blackholing of IP addresses. The problem is layer 9: if a mechanism of this form is standardised, it will be viewed by governments, courts and law-enforcement a centralised big red button which can be pressed at will to block IP access to their bêtes-noires du jour. And it turns out that there are lots of things that governments, courts and LEAs don't like, ranging from file sharing to witchcraft (one of the default blocking categories in the UK) to youtube (lots of countries) to google (france), to whatever. It's not just DDoS that will be targeted here. The proposal itself has raised an unusual level of disquiet among the IXP community, which seems to be split down the middle about whether standardising blackhole communities in an RFC is a good idea or not. Some IXPs think it's great. Others think it's a terrible idea. For sure, there is no consensus about this in the IXP world. Nick
