- 48% of announced prefixes (162 of 335) have no valid ROA, 20 of them RPKI invalid
- Only one upstream seen in the AS paths of its routes
- Announces 6 prefixes that RPKI assigns to another network (possible hijack or misconfiguration)
- 5 prefixes registered in IRR route objects for another active network and not authorized by a ROA
