what does that mean? BCP 38 is what the remote networks should do. we've
been pushing it into industry for 15 years. if more remote networks
would do it then spoofed-source amplified reflecting attacks would be a
but it's not something a DNS operator can do on their own network.
and there is no scalable practical way that victims can find out which
network's lack of BCP 38 enforcement is hurting them, so they don't even
know who to ask "please install BCP 38". and may of those networks'
operators, if they could be found, would say, "it's hurting you not me,
i'm not going to make the investment."
so, no, "enough" has not been "said". please make a specific proposal
that is actionable by the operators of name servers who are being used
as amplifying DDoS reflectors. that is the topic here. that's what DNS
