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!

Has this situation changed yet?

I've finally managed to get my IPv6 working with OpenWRT... took way longer than it should have...
One that really bugs me is the non-static prefix. I have services I host from my machine (i.e. RDP/SSH/etc.), which I connect to via a web address (derp.example.com). Often having to update said address because my prefix is changed...

Very frustrating.

I bug them every few months or so, but it's quite a low priority for them. It annoys me too as I have to update DNS entries every time my prefix changes.

Curious why you guys need static IPv6 addresses. Are you running servers at home? Or is there just the (reasonable) assumption that the ip6 address of a device never changes?

Running servers in our office that have DNS entries (on our internal DNS and externally).

I run RDP and SSH as well as a couple of other services for my own personal use. Problem is, my only solution is to
a. have a DDNS service running on my machine (don't like) and
b. open port X to ALL on my LAN, rather than just a single IPv6 address, since they aren't static.

It seems stupid, given how many IPv6 addresses there are, that we don't have static ones to begin with.

I was finding that when the prefix changed, I would no long be able to access other machines on the lan if they both had ipv6 enabled, it would still resolve to the old v6 address which was now out on the internet somewhere. Wait a while and it would come back.

Annoying. Turned ipv6 off as a result.

I also sent Snap a tweet a few days ago, but haven't heard anything back.

I'd imagine Snap don't particularly care about static prefixes, as nothings actually mentioned on their site either.

Hey guys, never knew there was much demand for this in the public space. I saw this post 2 days ago, and chatted to the guys. We enabled it and tested it from home and it seems to be working well.

If your modem/router can handle it we now have static IPV6 addresses and can provide static v4/v6 combinations if your router has dual stack as a backup. Im sure there will be some devices/applications out there that arent v6 ready.

I think you're going to find demand for it from most people who want to open a port to their VPN appliances, RDP, etc etc.
You have to allow the traffic through the firewall in order to get it to the PC, which is a manual task unless you use UPNP, which is a massive security risk IMO - coming from a background where security is paramount.

Surely Snap are going to need to start assigning static prefixes at some point? There really is no reason not too..
