Hi, Probably we don't need to spoof all address space, instead only if spoofing enabled just spoof to some predefined address range. Regards. /Alex Sanjeev Gupta <ghane0@gmail.com> wrote:

I support this point of view. I think controlled (anti-)spoofing measurements performed by the RIPE NCC with the consent of participating probes would be a good service to the community.

perhaps the probe owners are not the only parties with skin in the game and whose consent would be relevant?

Exactly.  I host probes, and since you are spoofing others, we need to ask them.

How you do this is left as an exercise to the reader.
