Abe - 

Static versus dynamic address assignment isn’t the problem - dynamically assigned IP address space can 
still be tracked back to a given system (reference: RFC6302/BCP162 & RFC6269 for discussion of the 
requirements and various related issues.) 

Tracking back to a particular server doesn’t really matter if all that happens is that the service is terminated 
(as the culprit will simply appear elsewhere in the Internet with a new connection/server and start over.)

Alas, the situation doesn’t change unless/until there’s a willingness to engage law enforcement and pursue
the attackers to prevent recurrence.  This is non-trivial, both because of the skills necessary, the volume of 
attacks, the various jurisdictions involved, etc. – but the greatest obstacle is simply the attitude of “Why bother,
that’s just the way it is…” 

With zero effective back pressure, we shouldn’t be surprised as frequency of attempts grows without bound.


Disclaimers: my views alone – no one else would claim them.  Feel free to use/reuse/discard as you see fit.
