Random-IP probe (yarrp) into the AS' prefixes

At least one router inside AS208328's announced prefix replied during the random-target probe. Hop(s): 2a06:9f42::1, 2a0a:6046:ffe0::. 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 2026-05-30T12:45:48Z
