    Announced as 104.233.0.0/21 by AS212238.

  • Warning

    No ROA covers this route (RPKI not found).

    Without a ROA, networks cannot tell your route from a hijack.

    Fix: Create a ROA for this prefix and origin at your RIR portal – it takes a few minutes.

  • Warning

    Seen by only 0% of RIPE RIS peers.

    Partial visibility points to filtering, a missing IRR route object, or an RPKI problem.
