Dear friends of integers, http://bgp.potaroo.net/v6/v6rpt.html appeared in an discussion on an IRC channel recently, and it occurred to me that a crucial bit of information is not available, namely "What is the total amount of IPv4 address space announced by ASNs which do (not) also announce IPv6?" (or variants of).
Argument was around how large % of IP4v address space is owned by long-tail ASNs, which have quite minor relevance to the major rolling out of IPv6 in terms of absolute number of internet hosts covered (circa). I have not seen this statistics reported anywhere, but I believe at least one of our list members have the source data to produce this information (hopefully with relative ease). Best regards, Martin
