From: Owen DeLong <owen () delong com>We had this discussion on the list exactly a year ago. At that time, the average IPv6 origin ASN was announcing 1.43 routes. That figure today is 1.57 routes per origin ASN.That represents a 10% growth in prefix/asn for IPv6. Compare to 9.3->9.96/ASN (7%) in IPv4 over that same time, While I would agree that this is a trend that merits watching, I think we're probably OK for quite some time.
By the time it's a problem it'll not be fixable. I've been a supporter of classful allocation of v6 such as Bill mentioned (http://lists.arin.net/pipermail/arin-ppml/2009-November/015521.html) there's enough space for it but people don't want to do classful again. If there isn't standard filtering of defined prefix/lengths by major carriers then we're just waiting for the problem to arrive. I don't think we'd get enough people to agree on this to avoid it. brandon
