192.88.99.0/24 no ROA MOAS

Announced by 2 different origins, which is either a deliberate multi-origin setup or a hijack.

192.88.99.0/24 is reserved by the IETF for 6to4 relay anycast, deprecated (RFC 7526). It is not globally routable, so it will not appear in the routing table or in any registry delegation.
This prefix is announced by more than one AS. Compare how many collector peers see each origin below: a hijack is usually visible as a second origin seen by far fewer peers than the legitimate one.
