Announcing a reserved ASN?

[Suresh Ramasubramanian <ops.lists () gmail com>]

AS23456 is currently announcing a good few netblocks (which don't have a
very good smtp reputation, by the way).

Funny thing is, that's a special use ASN as per rfc4893, something about
two octet ASNs that don't have a four octet representation.

Only one upstream (airtelbroadband-as-ap, as24560) that I can see
