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 SLO host (T-2) - reached via an VIX / AAIX / SAIX / TIROL-IX / ERA-IX-resident transit operator.
RPKI & ASPA
6 of 6 prefix(es) covered by a valid ROA.

Random-IP probe (yarrp) into the AS' prefixes
We probed 70 arbitrary IPv6 address(es) inside AS8666's announced prefix(es). No router inside the prefix responded. The deepest visible hop was 2a00:11c0:47:3::13 at hop 14 - that router answers ICMPv6 Echo. This is not in AS8666'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 ↗
