Random-IP probe (yarrp) into the AS' prefixes
At least one router inside AS202870's announced prefix replied during the random-target probe. Hop(s): 2a07:7e80::5, 2a07:7e80:acb:1::12, 2a07:7e80:acb:1::2, 2a07:7e80:acb:1::6, 2a07:7e80:acb:2::12. 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 2026-05-30T12:46:18Z
