Routing health

  • AS4758 announces 214 IPv4 and 65 IPv6 prefixes.
  • 6 of 279 announced prefixes are RPKI invalid: 164.100.189.0/24, 2001:4408:6d00::/45, 2001:4408:1141::/48, 2001:4408:1180::/44, 2001:4408:6200::/48 (+1).
  • 267 of 279 announced prefixes are RPKI valid.
  • 6 announced prefixes are not covered by a ROA of AS4758 (they may have none, or another network’s).
  • 2 upstreams and peers, 5 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.
