Its a 6 weeks old entries in my routers.
Even "oddish" its 26272 coming of GTT & HE.
26272 is unassigned at ARIN.
Looks likeAS26272 and 188.8.131.52/22 have been deregistered about a week ago.
In ARIN delegation statistics from Nov 8, ftp://ftp.arin.net/pub/stats/arin/delegated-arin-extended-20161108 these are listed as assigned and allocated but in later files that changed to 'reserved'.
RIPEstat shows 184.108.40.206/22 has been in the routing system with origin AS26272 since October 2012.
