Routing health

  • AS61574 announces 1 IPv4 and 91 IPv6 prefixes.
  • 92 announced prefixes are not covered by a ROA of AS61574 (they may have none, or another network’s).
  • One upstream or peer seen (AS47065): 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.
