Routing health

  • AS11351 announces 130 IPv4 and 13 IPv6 prefixes.
  • 124 of 143 announced prefixes are RPKI valid.
  • 19 announced prefixes are not covered by a ROA of AS11351 (they may have none, or another network’s).
  • One upstream or peer seen (AS7843): 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.
