VIX / AAIX / SAIX / TIROL-IX / ERA-IX peering
Not an VIX / AAIX / SAIX / TIROL-IX / ERA-IX member, but our traceroute path crosses the VIX / AAIX / SAIX / TIROL-IX / ERA-IX LAN from SRB host (SOX, Belgrade), SLO host (T-2) - reached via an VIX / AAIX / SAIX / TIROL-IX / ERA-IX-resident transit operator.
RPKI & ASPA
1 of 2 prefix(es) covered by a valid ROA, 1 not-found.
| Prefix | RPKI state | Reason | Covering VRP(s) |
|---|---|---|---|
2a0f:8000::/29 | - not-found | no covering VRP | |
2a00:63c0::/29 | ✓ valid | matched VRP (correct origin, length within maxLength) | AS44133 /29 maxLen 29 (ripe) |
Random-IP probe (yarrp) into the AS' prefixes
We probed 70 arbitrary IPv6 address(es) inside AS44133's announced prefix(es). No router inside the prefix responded. The deepest visible hop was 2a01:190:1650::2 at hop 11 - that router answers ICMPv6 Echo. This is not in AS44133'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.
method: ICMPv6 Echo + forged PTB, tested 2026-09-23T13:33:08Z
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 ↗
