6to4 route at AS27552? (AS7922?)

[Ivan Shmakov]

	As it seems, 6to4 addresses (2002::/16) are not reachable from
	AS27552.  As per their route server [1], their next hop appears
	to be AS7922, which is where the packets are finally lost.
	Then, their route server [2] seem to confirm that there's no
	route to 2002::/16:

  1 2001:558:0:F502::1 4 msec 4 msec 4 msec
  2  *  *  *
  3 2001:558:0:F743::2 !H  *  *

	Unfortunately, I fail to recall on how do I check whether
	AS27552 should forward the traffic towards 2002::/16 to AS7922
	or not.  (And, thus, whether I should contact the AS7922 admins
	regarding the issue, or the AS27552 ones.)

	Any suggestions?  (Apart from leaving the wonderful world of
	6to4, that is.)

	TIA.

PS.  Also to note is that, e. g., AS6939, which announces 2002::/16 (as
	well as 2001::/32) seems to share a few peers with AS7922…
