Routing health

  • Partial result: RIPEstat did not return the overview in time.
  • AS17511 announces 66 IPv4 and 2 IPv6 prefixes.
  • 42 of 68 announced prefixes are RPKI valid.
  • 26 announced prefixes are not covered by a ROA of AS17511 (they may have none, or another network’s).
  • 25 upstreams and peers, 10 downstream networks seen.

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.
