I agree with Willy's answer (IPv4 works well and upgrades may be
necessary). I have more to add. . .
IPv4 is well understood. Wherever you learned networking, everything you
learned used IPv4 examples. It uses normal-looking decimal numbers (with
odd boundaries for subnetting and a maximum of 255), and everything you
use supports it already. IPv6 addresses use hexadecimal, which looks hard.
AFRINIC still has IPv4 addresses for whoever needs them. Nobody in
Africa has run out of IPv4 addresses, so they are not worried. This
isn't quite true: every mobile provider has more users and devices than
IPv4 addresses, but we all don't even think about the extra cost of the
carrier-grade NAT (CGN) in mobile, because we think it's normal. I know
of at least one mobile network who deployed IPv6 just so they could
lower their CGN cost, and they have cut it by more than half.
There may be devices that don't support IPv6. For mobile, this might
include some low-end or very old handsets. For fixed broadband, it might
include very old edge devices (pre-2010 CMTS or BRAS, for example) or
modems (pre 2008) or home gateways. Of course, if many do support IPv6,
then you still gain that advantage.
For web hosting companies, IPv6 is easy. Several data centers and
content companies are entirely IPv6 internally, and provide IPv4
translation for those who need it.
All of this is about to change. I see that Exhaustion Phase I
(https://www.afrinic.net/2017-01-16-afrinic-is-approaching-ipv4-exhaustion-phase-1)
has slowed the allocation of IPv4 addresses
(http://www.potaroo.net/tools/ipv4/plotend.png). It looks like we will
reach Exhaustion Phase II within a year, which means organizations will
only be able to get one /22 at a time (though with no limit on the
number of times they can get more space if they've used 90% of all
allocated space). At that time, we will be only six months away from
running out, assuming the last /12 remains reserved.
IPv4 runout will hit Africa next year. Anyone needing more addresses
will first have to spend money to buy IPv4 addresses or CGN, and then
begin their IPv6 deployment.
I would love to see someone inside Africa measure IPv6 speed, and use it
to promote their service. One mobile carrier and one hosting company in
the same country might quickly become dominant. Maybe someone would host
a dual-stack Speedtest site.
