Thank you Geoff.

I asked because I could see 1/8 of merit AS237 but couldn't see
of origin AS36561 for those two in database.
Even if it's an experiment and sort term, It's better to be registerd
in right origin I think. # It could be guessed but...

which databases?

These ought to then get around to other IRR-ish-things when their
propogation times hit, yes?

|Hi,
|
|As I noted in the previous note quoted below, APNIC are undertaking a second experiment with these two /24 routes 
originated by AS 36561. These two /24s appear to be the major attractors in the 1.0.0.0/8 space. YouTube have 
generously provided assistance for this second experiment, and we are very grateful for their help!
