[lir-wg] PI Space and IXP routing

Just my .2 cent question.

When there are only a small number of ixp´s in the world (maybe 100) and
they are interested to route there networks worldwide (e.g. critical
services) and the community has two reasons to not allow this.
One reason could be not to put all /24 into my routing table and second i
don´t want to get problems in the peering mesh. What could be the solution:
a. filterlist in the peering mesh router of the isp and
b. give every ixp a /22 or /23
I know we are wasting valueble ipv4 space here, but look at the numbers of
ixp and compare them to the /24´s.
But then we need a really simple and in every way exact definition of an
ixp. Maybe this construct is also possible with ipv6? And please stop to
argue that the ixp could get address space from the uplink provider. There
are so many companies that broke in the last two years, that the possibility
that my uplink goes down is very high in Germany. Then I would request at
ripe to takeover the addressspace. The ixp would do this, because he did not
want to renumber the peering mesh. Why should ripe not give it right at the
start.
Comments welcome.
