Hi,
Hi all,
I will like to know, from those deploying IPv6 services to residential customers, if you are planning to provide static or dynamic IPv6 prefixes.
Just to be clear, I'm for static prefix delegation to residential customers, however I heard that some ISPs are doing dynamic delegations, the same way as is common today with IPv4.
I don't thin it make sense, as the main reason for doing so in IPv4 was address exhaustion and legacy oversubscription models such as PPP/dial-up.
well, it does make sense for most of the residential customers nowadays, because they are indoctrinated with this idea of dynamic+NAT == privacy for over a decade now and don't know any better.
IMNSHO, education is always a better alternative than preserving ignorance or worse, mis-information.
So, i don't think it's a good idea to hand out static prefixes to residential customers by default, it might cause pain.
I think it is an excellent idea to do so. I think that any delusions of privacy achieved through dynamic+NAT are exactly that and need to be shattered. The sooner, the better.
The best current practice would be, to default to a dynamic prefix, but enable your more advanced customers to change that to a static prefix at will in your customer service web-portal or something.
Sounds unnecessarily complicated and with absolutely no benefit whatsoever.
But i have no idea how to sell this to your marketing department. They again are usually used to sell static IPs for an extra fee, and usually don't want to change that with IPv6. That's bullshit for IPv6 of course.
It was mostly bullshit for IPv4.
(Another idea, which i scrapped after thinking about it in depth was, to hand out a dynamic P2P prefix (/64) + a /56 (or /48) static on top, so the customer/CPE could chose what to use, but that is actually too complicated in the end and would need support in the CPE firmware)
By default, we (Hurricane Electric) hand out a static /64 for the tunnel point-to-point and a static /64 for the customer LAN. Upon request we will also issue the customer a static /48 for their LAN structure. Owen
