It is up to IANA as to how they implement the delegation. We just
specify the requirements (insecure delegation to a empty zone). We
don't need to prescribe *where* leaked traffic is sunk. IANA has
decades of experience with moving traffic flows if needed.
The simplest delegation is back to the servers for .arpa. The
servers can be updated by IANA if/when they need to sink the traffic
somewhere else. The AS112 server however not the set of servers
to sink the traffic too as they are not under IANA's control and
there is no way to get them all to serve home.arpa.
If there is another round I would remove
, and MUST point to one or more black hole
servers, for example 'blackhole-1.iana.org.' and 'blackhole-
2.iana.org.'
as it is a over specification. Just let IANA manage it.
B.T.W. blackhole-1.iana.org and blackhole-2.iana.org aren't really
blackholes as they respond to queries. Operators if blackhole-1.iana.org
and blackhole-2.iana.org are required to ensure that they do answer
and to withdraw routing anouncements for them when they fail to do
so.
