Then each CGN as it gets more ALGs, has a lower performance, so you need to buy more CGNs. Then you also need to buy more IPv4 addresses! And what about the cost of logging?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;color:black'>In the case of 464XLAT, you *<b>don’t need</b>* to buy more addresses, you can even transfer a big portion of your existing ones and get some money back!

Goverments must not buy anything (not just hardware, software or connectivity, also human resources and other services) that doesn’t support IPv6 (and not just dual-stack, it must be able to work in an IPv6-only environment when needed), because that’s paid with money from citizens (tax payers), so it will be against law to do a bad expenditure, right? Furthermore, if goverments mandate the IPv6 support, all the ISPs will also start providing the service to business and householders.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;color:black'>And last, but not least.

Just for 2.000 municipalties (still not talking about all the other government offices …), the cost of doing with IPv4 is about 340.00.000 USD. Which IPv6-only, including 2 government datacenters (main and backup) is about 40.000.000 euros. This is only including the equipment, human resources, IP/ASN resources and connectivity cost – including VoIP (not including any buldings). Of course it need to be tailored for every case, not all the countries have the same number of connected offices, they may have already a DC, etc.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;color:black'>So savings every 5 years (those figures are calculated for 5 years terms, assuming that you renew your equipment every 5 years) is 300.000.000 USD for 2.000 government connected offices.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;color:black'>Is that making sense for moving to IPv6-only?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;color:black'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;color:black'>Regards,<o:p></o:p></span></p><p class=MsoNormal style='margin-bottom:12.0pt'><span lang=EN-US style='font-size:12.0pt;color:black;mso-fareast-language:EN-US'>Jordi<o:p></o:p></span></p><p class=MsoNormal style='margin-bottom:12.0pt'><span lang=EN-US style='font-size:12.0pt;color:black;mso-fareast-language:EN-US'>@jordipalet<o:p></o:p></span></p><p class=MsoNormal style='margin-bottom:12.0pt'><span lang=EN-US style='font-size:12.0pt;color:black;mso-fareast-language:EN-US'><o:p> </o:p></span></p></div><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:12.0pt;mso-fareast-language:EN-US'><o:p> </o:p></span></p><div><div><p class=MsoNormal style='margin-left:35.4pt'>El 31/5/20 12:57, "Mark Tinka" <<a href="mailto:mark.tinka@seacom.mu">mark.tinka@seacom.mu</a>> escribió:<o:p></o:p></p></div></div><div><p class=MsoNormal style='margin-left:35.4pt'><o:p> </o:p></p></div><p class=MsoNormal style='mso-margin-top-alt:0cm;margin-right:0cm;margin-bottom:12.0pt;margin-left:35.4pt'><o:p> </o:p></p><div><p class=MsoNormal style='mso-margin-top-alt:0cm;margin-right:0cm;margin-bottom:12.0pt;margin-left:35.4pt'>On 31/May/20 11:58, JORDI PALET MARTINEZ via RPD wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal style='margin-left:35.4pt'><span lang=EN-US style='font-size:12.0pt;mso-fareast-language:EN-US'><br><br></span><o:p></o:p></p><p class=MsoNormal style='margin-left:35.4pt'><span lang=EN-US style='font-size:12.0pt;mso-fareast-language:EN-US'>I’m not sure I’ve mention this before in this list, but our studies and customer cases demonstrate that using 464XLAT, typically 75% of the traffic will be already IPv6.

The majority of Internet access in Africa happens over a GSM network (2G, 3G, 4G/LTE), which represents millions of users in almost every African country.

And by extension, if the mobile operators get their customers on to IPv6, it will pressure other non-mobile, terrestrial operators (FTTB, FTTH, ADSL, hosting, e.t.c.) to get the act together, as they will need to keep up with the mobile eye balls, a much easier task for that side of the connection.<br><br>If there are any mobile operators on this list, if you're listening, I won't stop harping on about your role in keeping IPv4 a relevant (or irrelevant) headache for Africa.<br><br>Internet regulators in Africa on this list, if you're listening, make IPv6 deployment on all mobile services a requirement for license renewal, in lieu of trying to find new ways to squeeze more money from mobile operators with no tangible benefit for the end-user, and the continent as a whole.<br><br>Mark.<br><br><o:p></o:p></p></div><br>**********************************************<br>
