Yakov,
I know, it's not ideal, but then again I think there is some urgency in getting CIDR really off the ground by now...
I think this should be *strongly* encouraged. We should clearly steer away from search for an "ideal" solution, and rather focus on pragmatic considerations.
Agreed. I am trying to do some "structured pragmatic testing" now. SURFnet currently is announcing 192.87.108/22. Two out of the four Cs in this blocks are also explicitly annonced (192.87.108.0 and 192.87.110.0, these are production nets). I currently have a box (my personal laytoy) running in 192.87.111.0 and on the SURFnet backbone this network is routed. You can try to reach my box (192.87.111.59) doing pings or traceroutes (only), I leave it on tonight, but please be gentle to the laptoy :-). I am currently trying to ping to lots of regionals out there and making a list out of the results. I hope to publish something for real on this tomorrow. Here is a first glance: NET ASN REGIONAL COUNTRY RESULT ------------ -------- -------------------- ------------- --------- 133.11.0.0 AS372(?) NSN-AMES-AS(?) Japan Unreach 128.250.0.0 AS372(?)
