Also http://www.openresolverproject.org But it's not just about NTP and DNS, pretty much any UDP-based service that can do amplification is in play, e.g SNMP, Chargen and I've even seen "QOTD" (UDP 19). One UK ISP came in for special mention during a lightning talk at NANOG on this topic yesterday, so if you haven't already checked your address space I suggest you do so ASAP. Universal BCP38 source address validation is needed more badly then ever :-( Keith
