This must never never happen in production systems.  You do not block an IP address if you haven't verified that it's not spoofed.  DOTS has nothing to do with this.

[TR] My point is DOTS can be used to convey the spoofed IP addresses, and the attack information can either be used to delegate the mitigation to a separate domain or filter traffic (e.g. using ACLs). For the latter case, the new paragraph should clarify the attack information of spoofed IP addresses will not be used by the orchestrator to filter traffic.
