What to fix

  1. Warning

    4 of 4 announced prefixes have no ROA (RPKI not found): 103.96.229.0/24, 202.226.40.0/22, 2001:df1:e500::/48, 2404:e040::/32.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS63773 and a max length equal to the prefix length:

    103.96.229.0/24 AS63773 max-length /24
202.226.40.0/22 AS63773 max-length /22
2001:df1:e500::/48 AS63773 max-length /48
2404:e040::/32 AS63773 max-length /32

    Open in RPKI / ROA validator Guide

  2. Warning

    4 of 4 announced prefixes have no IRR route object: 202.226.40.0/22, 2404:e040::/32, 2001:df1:e500::/48, 103.96.229.0/24.

    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 AS63773 in your RIR’s IRR database (or RADB).

    route: 202.226.40.0/22
origin: AS63773

route6: 2404:e040::/32
origin: AS63773

route6: 2001:df1:e500::/48
origin: AS63773

  3. Warning

    No abuse contact is published for AS63773.

    Other networks send reports of spam, attacks and hacked machines to the abuse contact. Without one, reports go nowhere and blocklists may list the whole range.

    Fix: Add an abuse contact to the registration: abuse-c in the RIPE database, an Abuse POC at ARIN, an abuse mailbox (IRT) at APNIC, AFRINIC or LACNIC.

  4. Warning

    No IRR as-set is listed.

    Peers and route servers build prefix filters from the as-set. Without one they fall back to the AS number alone, which breaks as soon as you have customers.

    Fix: Create an as-set in your RIR’s IRR database and add it to your PeeringDB record.
