That might be possible, but sending traffic to Europe vs another site smells like some other issue. It’s also interesting to look at the internalized CIDR it’s matching against. Take puck as an example. puck:~$ curl http://redirector.c.youtube.com/report_mapping -4 204.42.254.5 => ord31x04 : superx_isp_number: 1 (204.42.224.0/19) [u] puck:~$ curl http://redirector.c.youtube.com/report_mapping -6 2001:418:3f4::5 => sjc07s17 (2001:418:200::/39) [u] Many interesting results as a consequence. - jared
