I don't think the IXes are to blame at all. General end organisation multi-homing is far more to blame than peering. How many people are happily peering at WIX using PA space and private ASNs and having the RS' strip them?
Assuming this wasn't a rhetorical question, quick greppage of the looking glass output suggests 55 peers have private ASN and are advertising a non-zero number of prefixes. I'm not sure this supports an arguement of "peering causes v4 exhaustion" - I'd hypothesize that the majority of NZ organisations going to APNIC for a multihoming allocation aren't peering (but I've no data to back that assertion up). It would be worthwhile noting here that our policies for APE and WIX vary quite significantly here - on WIX we allow /29 and private ASN, on APE we tend to try and enforce /24 and public AS. Generally, if anybody comes to us and starts making muttering noises about wanting to multihome with both an IX and a transit provider, we push them towards a public ASN - it gets too hard to do sane path stuffing if the IX/ISP is stripping the private ASN. Apologies for the late thread wade in, I've been on holiday. Cheers Si
