RPKI & ASPA
1 of 1 prefix(es) covered by a valid ROA.
| Prefix | RPKI state | Reason | Covering VRP(s) |
|---|---|---|---|
2a04:a580::/29 | ✓ valid | matched VRP (correct origin, length within maxLength) | AS202339 /29 maxLen 29 (ripe) |
ASPA: this AS has published an ASPA record listing 2 upstream provider(s) that are authorized to propagate routes from it: AS20912, AS206355. 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
We probed 35 arbitrary IPv6 address(es) inside AS202339's announced prefix(es). No router inside the prefix responded. The deepest visible hop was 2001:40d0::1:f08a at hop 15 - that router answers ICMPv6 Echo. This is not in AS202339's announced prefix; operationally it's the AS-edge / peering interface (often on an IXP peering address or an upstream's /127 link). The traceroute boundary is the AS edge: ICMPv6 Time-Exceeded responses from anything inside this AS are filtered.
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 ↗
