ASPA: this AS has published an ASPA record listing 24 upstream provider(s) that are authorized to propagate routes from it: AS174, AS3491, AS4229, AS7195, AS8849, AS9009, AS12186, AS18450, AS20326, AS20473, AS21859, AS36236, AS40994, AS49544, AS51095, AS56630, AS60068, AS61317, AS62563, AS63023, AS136557, AS137409, AS199524, AS213683. 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 70 arbitrary IPv6 address(es) inside AS200325's announced prefix(es). No router inside the prefix responded. The deepest visible hop was 2a02:6ea0:1:6::43 at hop 24 - that router does not answer ICMPv6 Echo. This is not in AS200325's announced prefix; operationally it's the AS-edge / peering interface (often on a SIX 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.

Full per-method matrix (all four methods run at each vantage):

| belgrade | honored | no_tcp | partial | inconclusive |
| berlin | honored | no_tcp | partial | inconclusive |
| duseldorf | honored | no_tcp | not_honored | inconclusive |

| karsolink | honored | no_tcp | partial | inconclusive |
| odin | honored | no_tcp | not_honored | inconclusive |
| t2 | honored | no_tcp | partial | inconclusive |
✓ All vantages agree on method(s): icmp6-echo - the headline-method spread above is dispatcher noise, not a real Type 2 disagreement.
These vantage-level disagreements are rooted somewhere in the forward paths. Joining each per-vantage traceroute against the IP→AS lookup from our global yarrp mesh, the first hop where the paths land in different ASes is the most likely site of the offending filter / unreachable AS / Type 2 drop.
Suspect transit ASes (ranked by how often they appear at the divergence point on the path of the worse-classifying vantage): AS200325, AS3257, AS174.

Diagnosis is path-level, not packet-level: it tells you which transit AS is the prime suspect, not exactly which firewall rule is to blame. Use the tracepath6 output below (when available) for per-hop PMTU evidence on the same path.

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 ↗
