Thanks, but what if the attacker is many... like thousands ?  ...isn't that
typically what we see, is tons and tons of sources (hence
distributed....dos) ?

Look at Exabgp :
That's what I use in here : to
inject the prefixes in BGP.
I block the attacker's addresses, not the victim but if you are willing to
write your own scripts it does the job.
