A reason to de-aggregate down to /24s, to make hijacks more difficult/less effective? /kc On Tue, Mar 20, 2018 at 04:20:47PM -0300, Alejandro Acosta said:

Something apparently in Brazil is hijacking 128.255.192.0/22, part of 128.255.0.0/16 which is held by the University of Iowa.?? AS 263971 is announcing 128.255.192.0/22 which Hurricane Electric is accepting & propagating.?? None of that has any authorization.
I can't find any decent contact information for the originating entity, so I have reported it to abuse@he.net, but it'd be fabulous if some HE folks listening here could whack the hijacking faster than the abuse channels will get to it.?? Also useful would be some functional contact for AS263971.
Any help will be appreciated.
