RPKI & ASPA
1 of 1 prefix(es) covered by a valid ROA.
| Prefix | RPKI state | Reason | Covering VRP(s) |
|---|---|---|---|
2a00:1cc8::/30 | ✓ valid | matched VRP (correct origin, length within maxLength) | AS15605 /29 maxLen 40 (ripe) |
ASPA: this AS has published an ASPA record listing 5 upstream provider(s) that are authorized to propagate routes from it: AS3356, AS6762, AS12637, AS41327, AS56911. Routes from this AS that arrive via any other upstream are considered ASPA-invalid by validators that enforce ASPA.
Random-IP probe (yarrp) into the AS' prefixes
At least one router inside AS15605's announced prefix replied during the random-target probe. Hop(s): 2a00:1cc8:0:ff26:12f3:11ff:fe3e:c8f5, 2a00:1cc8:0:ff2e:8678:acff:fe37:c54a, 2a00:1cc8:0:ff49:5287:89ff:fe69:95b4, 2a00:1cc8:0:ff50:e2ac:f1ff:fe79:fdb4. These are candidate targets for direct testing.
ICMPv6 Type 2 (Packet Too Big) acceptance - active test
Type 2 honored. Forged ICMPv6 PTB (MTU=1280) was accepted by the destination's stack: the next 1500-byte Echo Reply arrived split into 2 fragments via the IPv6 Fragment Header.

Multi-vantage path map
Every hop of all vantages’ traceroutes toward the target, drawn left→right, grouped into per-AS bubbles (a hop seen from several vantages is one shared bubble, so converging paths merge). It answers two questions per vantage — shown on each source bubble as echo ✓/⚠/✗ · trace ✓/✗: did the destination reply to ICMPv6 Echo (✓ honored, ⚠ replied but PTB not honored, ✗ no reply), and did the traceroute reach it. A line to the target is drawn only when that vantage got an echo reply — solid if the PTB was honored, dashed if not (reachable but a broken-PMTUD / RFC 4890 violation). The path depth still shows how far the traceroute itself got, and runs of unanswered (* *) hops collapse into one dashed “silent” bubble. Open full size ↗
