Besides that, the RIRs have a similar policy in order not create
competition for a resource that is considered limited and i order to
limit routing table growth (the problem that is trying to be solved
by
having the IETF set the policy) . If the resource is not limited and
routing table growth is not an issue, let each RIR set their own
policy.
Wrong. If the resource is not limited and routing table growth is
not an issue, don't let each RIR set their own policy. Just assign
as much resource as demanded.
The resource is limited.
Then, we need some policy to deny some assignment based on the
technical reasoning on why, how and how seriously the resource
is limited.
The resource is limited as there is a fixed number of addresses. The
RIRs was created to handled and manage policy for a limited resource.
Let's use them for that. The IETF was created to develop standards let
them handle that.
