- I am under DDoS. What can I do? 4 answers
When I am experiencing DDoS @10Gbps, if I have BGP router with 10M table entries in it, can I perform search on the offensive network?
I would do this the way, that first I would remove routing to me for first /8 and see if DDoS will stop. And then search this way the source of the DDoS on the complete 32bit address space.
I am not familiar with BGP a lot, not sure how long it propagates and how long such search would take and what would be impact. Also not sure if I can actually prevent some network stop routing to me by their ip numbers I download from RIPE and Arin.
This is particularly for dealing with spoofed attacks, as normal ones can be traced more effectively.
Or how much bandwidth do I need and no of locations to sustain any kind of DDoS in Europe? I can re-route traffic with Route 53 latency based DNS. Recent disclosed strike I read about was around 13Gbps, would 20Gbps be enough?
