        Btw, I hope you folks would defer to Level(3)'s reannouncement
policy, which is very clear in their AS object located within RIPE's
IRR, which reads:

        If you are a provider who has been asked to route a
        more-specific network block that is part of 4.0.0.0/8,
        please ask your customer to contact Level 3 to obtain
        a new network block.

        Level 3 will not accept advertisements for any networks
        that are part of 4.0.0.0/8 from any non-customer peer.

      So, if you want to do what's "right", tell your customer to go
talk with Level(3), so they can renumber into IP space that would be
permitted to be announced more specifically.   If anybody wants to see
the comments in their as object, just look at
http://www.onesc.net/communities/as3356  it's very clear.
