Routing health

  • AS25490 announces 87 IPv4 and 1 IPv6 prefixes.
  • 3 of 88 announced prefixes are RPKI invalid: 62.183.38.0/24, 85.174.240.0/22, 85.174.248.0/22.
  • 83 of 88 announced prefixes are RPKI valid.
  • 2 announced prefixes are not covered by a ROA of AS25490 (they may have none, or another network’s).
  • One upstream or peer seen (AS12389): an outage there takes the whole network off the internet.

For every check with the fix (IRR route objects, the RPKI state of each route, reverse DNS and the registration), run the full network report.
