I can see that IPv6 is 24ms faster than IPv4 but why most of African companies or companies based in Africa still use IPv4?
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.

I recently listed all of the measurements I could find. https://www.retevia.net/fast/ In Africa on average, IPv6 is 24ms faster than IPv4. That can mean a significant difference in how long a web page takes to load. The APNIC data set is pretty small, though, and the performance improvement might just mean that the "Happy Eyeballs" algorithm only lets IPv6 work when it's faster: https://stats.labs.apnic.net/v6perf/XB I don't know how African mobile providers have deployed IPv6, but I compared some American and European mobile providers, and there's a correlation between 464xlat and slower IPv4. My guess is that Android handsets are a little slow when doing CLAT. https://twitter.com/WLeeCoyote/status/1102906933739249664 Lee > > On Sun, Mar 10, 2019, 13:00 <[email protected] <mailto:[email protected]> > <mailto:[email protected] <mailto:[email protected]>>> wrote: > > Send AfrIPv6-Discuss mailing list submissions to > [email protected] <mailto:[email protected]> <mailto:[email protected] <mailto:[email protected]>> > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.afrinic.net/mailman/listinfo/afripv6-discuss > or, via email, send a message with subject or body 'help' to > [email protected] <mailto:[email protected]> > <mailto:[email protected] <mailto:[email protected]>> > > You can reach the person managing the list at > [email protected] <mailto:[email protected]> > <mailto:[email protected] <mailto:[email protected]>> > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of AfrIPv6-Discuss digest..." > > > Today's Topics: > > ? ?1.
