Justin, Dial-up modem is just a layer 2 device with no IP address. Just think of it as a converter, its sole function is to convert the telephone line to something your PC can use, in this case, Ethernet. Both IPv4 and IPv6 operate on the layer 3 of the OSI model which is taken care of by the RAS. So basically any dial-up modem support IPv6. -MJ -----Original Message----- From: Justin Wilson [mailto:lists@mtin.net] Sent: Tuesday, March 26, 2013 12:06 PM To: NANOG Subject: Re: Question on Ipv6 address I don't mean to hijack the thread so if someone wants to open a new one that¹s cool. But my question is what dial-up hardware supports v6? I am *assuming* Cisco does.

I'm new to Ipv6 and trying to understanding something about IPv6 in service provider network. I've got the following questions , could anybody do some helps? 1. In a dial-up network (Q-in-Q for each customer who dials in ) Should each customer be assigned to ipv6 subnet prefix like /64 unique universily? I've read a rfc which stated point-to-point like should be assigned /64. But to my understanding, in dial-up network , each user should only needed to be assigned a single ipv4 address, with wich customer could used in his PC or his home router. 2. In dial-up network, could each vlan's ipv6 link-id be planned with its vlan number? if so, IP v6 address confliction could be avoided when BAS is assigned a /64 or longer prefix. 3. we are testing some BAS with IPv6 accessing, in radius accouting packets, there is IP-v6-prefix, Ip-v6-link-id, Ip-v6-delegated-prefix. how could dial-up PC's IPv6 address be calculated with above information? 4. should it be necessary to plan different IP-v6-prefix(IP-v6-delegated-prefix) for each dial-up customers in BAS? 5. How could delegated IPv6 prefix be used in service provider's network? is this useful in dial-up access network?
each word will be highly appreciated. Joe
