However I think this is an educational problem of those agencies Š you can't offer dynamic and stable services to access the home, and privacy goes beyond a stable address. So miss-protecting privacy actually is against user services. Regarding the routing table, my guess is that you should aggregate all the customer prefixes, in a small number of prefixes for each BRAS, PoP, etc., so no difference here with IPv4.

Regarding Jordis question I've to add that regulatory agencies in some countries are not voting for static/permanent prefix delegation to customers, because of privacy reasons.

Kind regards Olaf

Unfortunately you have to do static prefix delegation because it's impossible to renumber the customer's inside LAN within a reasonable time interval with today's state of IPv6 SLAAC.

However, static delegations might cause IPv6 routing table explosion unless you're very careful (with dynamic IPv4 address allocation you could define address pool on BRAS and advertise just the pool prefix into the rest of the network).

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.

Regards, Jordi

PS: I've sent this question to NANOG, got very few answers, so trying here ...
