What to fix

  1. Warning

    No IPv6 prefixes announced.

    Networks without IPv6 force their users through NAT64 or leave them unreachable from IPv6-only networks.

    Fix: Get an IPv6 allocation from your RIR (usually free with your IPv4 membership) and announce it.

    Open in ASN & BGP prefix lookup

  2. Warning

    2 of 2 announced prefixes have no ROA (RPKI not found): 199.87.170.0/24, 199.87.171.0/24.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS395838 and a max length equal to the prefix length:

    199.87.170.0/24 AS395838 max-length /24
199.87.171.0/24 AS395838 max-length /24

    Open in RPKI / ROA validator Guide

  3. Warning

    1 of 2 announced prefixes have no IRR route object: 199.87.171.0/24.

    Many networks build their prefix filters from IRR data; without route objects some of them drop the routes.

    Fix: Create route (IPv4) and route6 (IPv6) objects with origin AS395838 in your RIR’s IRR database (or RADB).

    route: 199.87.171.0/24
origin: AS395838

    Fix: Try again in a minute.
