Noah, you can't use that argument. Perhaps a better number to look
at would be how many ASN's there are in the routing table, and how
many of them are IPv4 only vs how many have both IPv4 and IPv6 or
even IPv6 only.<br>
<br>
Most ISP's run with one ASN but many run with multiple ASN's - but I
believe ASN's would be a better measurement.<br>
<br>
I, as an ISP advertise one /32 of IPv6, and multiple IPv4 prefixes.<br>

<div>In fact, I would argue that by insisting on holding
resources in the free pool for “possible future
newcomers” you are, in effect, assigning them to
organizations without any current proof of physical
infrastructure in the AfriNIC service region to the
disadvantage of organizations that do currently have
proof of infrastructure and a documented need for the
addresses within the region today.</div>

<div dir="auto">IMHO, your premise is flawed, i<span
style="font-family:sans-serif">n my experience (having
worked for 3 SP startups and still do),</span> because we
were all startups at some point when we involved ourselves in
the business of connecting folk to the internet and every iron
that we fired up then and today needed and still needs at the
very least an IPv4 address to connect to the internet. <br>

Occasionally at AFRINIC Meetings, we have an "IPv6 only" day.
Generally, most people survive just fine. I think this "IPv6 Only"
day event should perhaps be something we always do at our meetings.
Its also been done at SAFNOG (Southern African NOG) a few times.<br>

<div dir="auto">In anycase, IPv6 internet is still developing
sponteneously at almost 40k prefixes announced with a few case
studies around the US, Europe, Asian and some parts of Africa
and South America and could take another decade as long as
telecoms around the world still run CGN's. </div>
<div dir="auto"><br>
</div>
<div dir="auto">IMHO market forces and tech-dynamics (IoT) will
push for IPv6 adoption and until then, the over a decade
aggressive invetments in IPv4 internet will still stand even
though most equipment and software today pretty much supports
IPv6.</div>
