Just wait for GigE-everywhere. I am almost sure that these new Gig-to-the-toaster residential installs have very little rate filtering (or abuse response); let's hope that oversubscription solves the issue handily as it has traditionally. /kc On Tue, Nov 18, 2014 at 08:19:01PM -0600, Rafael Possamai said:
Some folks might disagree with this, but if it's an important service that I have running on a network, I will block a series of garbage AS's (closer to /8 the better) at the firewall (not at the edge) and that reduces the headaches by 50%. This isn't practical at the edge, but for system administration is the only way I have found to minimize the problem. A lot of times the owners of these IPs don't really care and won't take action. For example, the amount of garbage that comes out of FDC Servers in Chicago at times and not much is done.

Hello,
I provide broadband connectivity to mostly residential users. Over the past few years, instances of DDoS against the network - specfically targeting end users - has been on the rise, and today I can qualify many of these as simple acts of revenge where someone will engage a dos (possibly, services like 'booters' or similar) because they lost an online game or had some interactive in a forum they didn't like. I have good 'consumer broadband' filtering rules in place which make sense and protect against quite a lot of obviously ddos oriented traffic streams. The next step I want to engage, for those types of traffic which I can positively identify as not spoofed, is to send out abuse reports to owners of ip ranges used to launch these attacks. Ideally I'd like to be able to write up some form letter describing the attack, the source ip(s) of note, some disassembled sample packets, and then feed a list of IP source addresses and have it mail it out to the abuse contact at each source network. I am wondering if anyone has a pointer or reference to any tools which might help facillitate this?
Thank you.
