Approximate count of dependent hostnames if AS306 disappeared from the routing table.

Blast radius: Computing — check back later. The precompute pipeline refreshes this panel within a few days.

MOAS / hijack watch

Prefixes routed by AS306 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 AS306 is unique to AS306 in the current routing snapshot.
