VIX / AAIX / SAIX / TIROL-IX / ERA-IX peering

VIX / AAIX / SAIX / TIROL-IX / ERA-IX member - Open peering, peering member, since 2010-07-29. IPv6 LAN: 2001:7f8:30:0:1:1000:20:970. Locations: -.

RPKI & ASPA

1 of 1 prefix(es) covered by a valid ROA.

ASPA: this AS has published an ASPA record listing 3 upstream provider(s) that are authorized to propagate routes from it: AS21013, AS33891, AS200683. 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 35 arbitrary IPv6 address(es) inside AS200970's announced prefix(es). No router inside the prefix responded. The deepest visible hop was 2a01:4a0:0:2028::10 at hop 11 - that router answers ICMPv6 Echo. This is not in AS200970'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 2026-09-24T13:32:36Z

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 ↗
