Random-IP probe (yarrp) into the AS' prefixes
At least one router inside AS56911's announced prefix replied during the random-target probe. Hop(s): 2a01:a620:4:1::, 2a01:a620:5:1::. 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 2026-09-23T12:02:06Z
Where the path divergence is
Per-vantage probe + verdict (headline):
- belgrade: probe
icmp6-echo→ verdicthonored - berlin: probe
icmp6-echo→ verdicthonored - duseldorf: probe
icmp6-echo→ verdicthonored - go6lab: probe
icmp6-echo→ verdicthonored - karsolink: probe
icmp6-echo→ verdicthonored - odin: probe
icmp6-echo→ verdicthonored - t2: probe
icmp6-echo→ verdicthonored
Full per-method matrix (all four methods run at each vantage):
| vantage | icmp6-echo | dns-tcp | tls | http |
|---|---|---|---|---|
| belgrade | honored | inconclusive | partial | inconclusive |
| berlin | honored | inconclusive | not_honored | inconclusive |
| duseldorf | honored | inconclusive | not_honored | inconclusive |
| go6lab | honored | no_tcp | inconclusive | inconclusive |
| karsolink | honored | inconclusive | not_honored | inconclusive |
| odin | honored | inconclusive | not_honored | inconclusive |
| t2 | honored | inconclusive | not_honored | 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): AS56911, AS6939.
- From belgrade (open/Type-2=honored) the path enters an opaque hop at hop 11; from berlin (open/Type-2=honored) the same hop is in AS56911. Last common AS: AS56911. The disagreement is most likely rooted in one of those two transit ASes.

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 ↗
