hijacking of 128.255.192.0/22

Tue Mar 20 20:53:21 UTC 2018

Looks like this incident didn't start today. I show it starting back on
2/22 at 00:31:38 UTC. It then persisted till 3/19 where it started to
get withdrawn by most peers. It wasn't until 3/20 at 19:10:10 UTC when
it was globally withdrawn from all peers that were advertising it. 

I'll be like Job and plug monitoring. Had FaleMais and/or University of
Iowa been monitoring their own prefixes as well as what they advertised
(originate in this case), this could have been stopped when it started
almost a month ago.

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 at 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. ________________________________________________________________________ Jay Ford, Network Engineering Group, Information Technology Services University of Iowa, Iowa City, IA 52242 email: jay-ford at uiowa.edu, phone: 319-335-5555
