Re: [Wg-ipv6-guide] (ToC 7) Initial allocation criteria



I would hazard the guess that the default assignment model
is 'persistent'.

i.e. whether you acces the ISP via leased lines, CATV, ADSL, or
dial, you would, by default, use the same IPv6 prefix.

The case for dynamic assignment would be restricted to
mobile IPv6, where there is a true need for a temporary
address as a lower layer transport end-point identifier.

i.e. if an ISP assigns IP dynamically to its subscribers through DHCP,
then the subsriber:IP ratio is 1:1 with a /48 for each subscriber. Its just
that DHCP would use very long leases in order to provide
some form of persistence of address.

(After all if you use short leases, then what is the point of V6?)

Geoff

Hi, sorry for the late response.

Simply re-phrasing the policy may create another misunderstanding
about the wording, so why don't we have specific examples for the
cases that meets the criteria?

Static assignment(leased lines, CATV, xDSL)
 Each static IP address assignment for its customers can be considered
 as a /48 assignment.

 Existing IPv4 infrastructure/customers can also be taken into
 consideration.

 For example, if a CATV provider has 4,000 IP static connection
 customers in IPv4 and 5%(200) of them are expected to subscribe IPv6
 service connection, then, it this provider meets the criteria.

 This is not only restricted to the cases where they assign multiple
 static IP in IPv4. Even if you assign a single static IP in IPv4,
 it's upto the ISP to assgin /48 to these customers.

Dynamic Assginment service(mobile networks, dial-up, CATV, xDSL)
 I'm not sure how this will be evaluated, but if possible, it would be
 helpful to describe it.

 I am curious to know for example, if an ISP assigns IP dynamically to
 its subscribers through DHCP, but the subsriber:IP ratio is 1:1,
 would they be eligible for a /48 for each subsribers?
