Random-IP probe (yarrp) into the AS' prefixes
We probed 30 arbitrary IPv6 address(es) inside AS60798's announced prefix(es). No router inside the prefix responded. The deepest visible hop was 2a00:82e0:ffff::5b at hop 24 - that router does not answer ICMPv6 Echo. This is not in AS60798'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.
