No one has permission to announce that subnet. It is
apparently
being announced by TINET in Italy. I shall have to write to them
to find out what's going on. It may be a mistake or it may be a
prefix hijack; it wouldn't be the first.
Thank you for calling it to my attention. Somehow our
BGP monitoring
missed it.
I have 4 snapshots of the BGP routed subnet situation here, and this entry
is present in all of them. It apparently is not a recent change.
