If you have enough IPv4 address space, the easiest way to do IPv6 is to go dual-stack (both IPv4 and IPv6 to every customer), and then work on the transition technologies. Here's my "Learn IPv6 before lunch" reading list: https://www.retevia.net/recommended-reading-on-ipv6/ Here's a high-level guide for ISPs: https://datatracker.ietf.org/doc/rfc6782/ You may want to think about this as if your goal is run an IPv6-only access network, with translation to IPv4 at the edges where necessary. Let customers run dual-stack inside the home; so if a customer has devices in their home (alarm systems, smart TVs) that require IPv4, the home gateway can translate from IPv4 to IPv6, and if the destination is IPv4-only, you have a translator in your data center or peering point translating from IPv6 to IPv4. Jordi like 464xlat, but I like MAP-T (or MAP-E). Dual-stack Lite is also an option. In all of those cases, the hardest part seems to be getting support in the CPE. Here's a very short description of each: https://www.retevia.net/what-we-offer/ My experience is that most of your time will be spent working on your provisioning, monitoring, and support systems. Equipment generally supports IPv6, and you'll just have to read the manuals to find the right commands. Lee On 3/11/19 12:41 PM, Alessandro Valenza wrote:

Hello,

this is the first time I write in this mailing list.

I have a question for you.

I’m working for an ISP that obtained IPv4 (/22) and IPv6 (/29). I would like to use IPv6. Could you suggest me some documents and some manuals useful to implement IPv6, but avoiding problems for our customers?

In particular, I would like to avoid compatibility problems with VoIP PBXs, network printers, alarm systems, etc ...

In Italy only few ISPs provide IPv6 addresses and we would like to try to reverse this negative trend compared to the rest of Europe.

I hope you can help me understanding the advantages and opportunities in investing in the direction of IPv6.

Kind regards

Alessandro

For IPv6 CIDR addressing plans, take a look at: https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing#IPv6_CIDR_block... Please keep in mind in IPv4 world, a lot of customers assume their current modem/router to apply some sort of protection by providing NAT to hide all their equipment and selective apply port-forwarding when nessecary. While IPv6 provides plenty of addresses and there is no need to deploy NAT, customers still want some sort of security. Most vendors provide a similar functionality to block-all and selective allow traffic to specific IPv6 addresses/ports at the modem/router. Please document and communicate these features properly for your helpdesk and customers. Alessandro Valenza wrote at 2019-03-11 17:41:
