b.root acting weird via IPv6

[Daniel Roesen]

Hi,

$ dig . SOA +norec +short @2001:478:65::53
;; reply from unexpected source: ::ffff:127.0.0.1#53, expected 2001:478:65::53#53
;; Warning: ID mismatch: expected ID 52838, got 47170
;; connection timed out; no servers could be reached

Anyone got a clue how that can happen? Later attempts did evoke no
reply at all. DiG is 9.3.1. Not able to reproduce yet.

traceroute to 2001:478:65::53 (2001:478:65::53) from

$ ping6 2001:478:65::53

Filtering, I guess?


Best regards,
Daniel
