Firstly, the semantics of the two objects differ. A ROA is an
"authority" granted by a prefix holder that nominates an AS as a
potential originating AS. The key observation here is that the AS
holder is not necessarily aware of this ROA, or even necessarily aware
that such an authority has been granted or published, let alone be
prepared to announce the prefix as originating from this AS. The AS
holder cannot cause such an authority to be removed or revoked. In
contrast, a Route Object is a statement by an AS holder to the effect
that the AS is currently, or may in the future, announce a
particular prefix as originating from this AS.
this is completely false. a route: object is a statement by the prefix
owner of what as may announce, just like a roa; surprise surprise.
both ripe and arin, who seem to understand the technology a bit better,
will be doing this. as it only really needs to be done once for the
whole internet, if the secretariat wants to throw up chaff to not do
this, no problem.
