I shall point Adrian to your forum post here.

Your CPE should be requesting the /48, and splitting it up for your LAN. Each network should be getting a /64 out of that /48 (which gives you around 65k networks you can operate)

If your machines are getting an IP address out of the delegated prefix, and you can connect to things like http://ipv6.google.com then I wouldn't worry too much.

In reply to a post by mixt:

The /48 is not routed by default. From Zen directly (yesterday, when I was wondering why the /48 was not being routed):

Ah, fair enough. I have statically configured some prefixes from the /48 (/128s for loopbacks etc.) which are not configured with DHCPv6-PD and had no problems, I do however also have a few /64s configured with DHCPv6-PD. It looks like the full /48 is routed once the PD request is made then.

DHCPv6-PD works by requesting a prefix. Your CPE then splits this up for you. When you make the request, Zen will be sending you the full /48, and you do with it what you want. This will be why your /128's are working.

Does your PC have an IPv6 address?

I get the following:

$ ipconfig

Windows IP Configuration

Wireless LAN adapter Wi-Fi 2:

I can then ping my gateway (remove the %4 off the end)

$ ping fe80::ae22:bff:fe24:a658

Are you getting this far?

IPv6 is not about Zen running out of addresses, its about the world running out. Its no good you having an IPv4 address if you can't reach a new service that is IPv6 only.

There is a good FAQ about IPv6 here: http://www.internetsociety.org/ipv6-frequently-asked...

DHCPv6-PD works by requesting a prefix. Your CPE then splits this up for you. When you make the request, Zen will be sending you the full /48, and you do with it what you want. This will be why your /128's are working.

In this case the CPE is subnetting the single delegated /48 prefix itself yes, but that isn't always the case. Some implementations require the requesting router to make a separate request (IA_PD) to the delegating router for each prefix required, in which case the delegating router may only route the individual prefixes, rather than the shorter covering prefix.

In reply to a post by ZenUserJP:

ive wasted 2 hours of my life trying to get this to work on my Billion 8800NL I have a LAN and WAn ipv6 address but none of the testers here work

As Zen do a static why are we all worried we are going to run out of IPs anyway? or have I got the idea totally wrong?

because its a worldwide issue, eventually web content will become ipv6 only due to the lack of ipv4 addresses, and if at that point you dont have ipv6 connectivity then you dont get to view that content.

e.g. hetzner a large german hosting isp, now will only supply one ip per server due to the shortage.

Some isp's do of course appear to have large stocks of ipv4, e.g. openitc in the uk are supplying entire /24s per server which is somewhat irresponsible but shows they must have a lot left. But they do charge a hefty premium for those servers. However because some isps are ok it doesnt mean everyone is.

In reply to a post by tehdan:

Of course A&A do it the hard way,

<sarcasm> Indeed. 2 days so far unable to get Zen's attempt to work - When I was with A&A it took all of 2 seconds.

The very hard way indeed! </end sarcasm>

I am on a Mac, but the Router does have an IPv6 address yes

Does your mac have an IPv6 address? If it doesn't you're not going to get very far.
