RPKI & ASPA
3 of 3 prefix(es) covered by a valid ROA.
| Prefix | RPKI state | Reason | Covering VRP(s) |
|---|---|---|---|
2a02:2888::/33 | ✓ valid | matched VRP (correct origin, length within maxLength) | AS8265 /32 maxLen 48 (ripe) |
2a02:2888::/32 | ✓ valid | matched VRP (correct origin, length within maxLength) | AS8265 /32 maxLen 48 (ripe) |
2a02:2888:8000::/33 | ✓ valid | matched VRP (correct origin, length within maxLength) | AS8265 /32 maxLen 48 (ripe) |
ASPA: this AS has published an ASPA record listing 3 upstream provider(s) that are authorized to propagate routes from it: AS6453, AS6939, AS51569. 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 AS8265's announced prefix replied during the random-target probe. Hop(s): 2a02:2888:8265:100:195:96:194:105, 2a02:2888:8265:100:195:96:194:106, 2a02:2888:8265:1ff:0:5:1569:1. 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.
method: ICMPv6 Echo + forged PTB, tested 2026-09-23T12:02:40Z
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 ↗
