As many know, COX Business Internet (SOHO) customers still do not have native IPv6, no doubt due to issues providing static IPv6 prefixes to business customers. Business customers often have downstream routers that require static IPv6 prefixes.
A step in the right direction would be for CBI to enable stateless NPTv6 (Network Prefix Translation) using ULA (Unique Local Addresses, ie. fd00::/8) on their routers.
Ref: What are ULA's, Unique Local IPv6 Generator:
http://unique-local-ipv6.com
But ULA prefixes are not globally routable, how would this work ?
A CBI customer generates a good pseudo-random fdxx:xxxx:xxxx::/48 prefix, and carves-up the /48 into /64's for local use, all manually assigned by the customer.
From the customer's endpoint an outbound fdxx:.../64 packet is transmitted upstream, COX's router translates that to 2xxx:.../64 and adds a dynamic fdxx:.../64 route back to the customer's endpoint. Corresponding return packets are translated to fdxx:.../64.
Is this possible to do with your equipment, COX ?
This could be equally applied to Residential customers if desired, in parallel with DHCPv6-PD.
While supporting ULA with NPTv6 is not the total answer as this does not allow for running public IPv6 servers, it still is a useful tool in the toolbox, even when static, globally routable IPv6 prefixes are offered in the future.
