I'm looking at getting a Snap connection -- VDSL and IPv6 are the big drawcards.

From what I hear
* you get a /48
* it changes every time you get a new PPP connection

How hard is it to configure subnetting and other routers if your range is dynamic?  If I want 3 /64 subnets on different layer 2 domains, how much of a pain will that be to keep up with the new /48s?

Are there any plans to make the v6 ranges static (or at least provide the option)?

Subnetting is sooooo easy with IPv6. Your could have ridiculour numbers of /64s out of that /48

e.g. we have

2004:4005:4800::/48

so we have our first /64 as

2004:4005:4800::/64

second as

2004:4005:4800:1::/64

third as 2004:4005:4800:2::/64 etc.

You should definately get a static or at least sticky assignment.

Oh, I know it's really easy when you have a ::/48.  I've had IPv6 at home before.  But never with a dynamic address range.  Snap support say that dynamic is what you're stuck with.  I want to know (a) is it worth the effort to do subnetting when the ::/48 could change on me the next time my router gets restarted, (b) how would I do subnetting in that scenario, (c) are there any plans to offer static v6 addresses to DSL customers.

XNet does static v6 prefixes. SNAP is tempting to switch to, but a) effort and b) dynamic v6 prefixes, which makes it pointless. (For me, at least. Since I actually use v6 IP's to get to my boxes at home on xnet)

It is a bit annoying having a dynamic ipv6 address. Our Snap VDSL connection has changed ipv6 subnets 3 times in the last 24 hours. Apparently they are doing static allocations soon, but they've been saying that for months.

Almost as bad as xnet!
