MOAS / hijack watch

Prefixes routed by AS3300 that another Autonomous System also announces. A non-empty list is one of the strongest BGP-hijack signals available without active probes.

No active MOAS conflicts. Every prefix announced by AS3300 is unique to AS3300 in the current routing snapshot.
