Hi All,

We have some great news – we have finished our platform upgrades and can now provide you with static IPv6 addresses!

At the moment we are still working on our automation platform that will allow you to request this on the “My Snap” page – however we are able to manually provision these for you for this to happen please email your request for a static IPv6 to support@snap.net.nz

FAQ’s on static Addresses

1.      The allocation size is a /56
2.      IPv6 support is via our email helpdesk – support@snap.net.nz
3.      Your static allocations may change if you move house

Any questions please post here!

Cheers,

Ralph

Hi Ralphfromsnap,

If I have a static ipv4 address, will I automatically get a static ipv6 or will I need to pay extra to get that?

Cheers,

Chris

Hi Chris,

Our static IP charge ($10 per month) covers both IPv4 & IPv6. Static IPv6 is not automatic so you'll need to flick us an email requesting this

I would be interested to know why only a /56 is being allocated per customer. The standard assignment for IPv6 prefixes is a /64, and there is software out there that only works with a /64.

lol what kind of software works with a /64 only?????

Just because they give you a /56 doesn't mean you need to use it all. Just use a /64 if you only want to use a /64 - you can have SLAAC and 255 more subnets then too (for modest growth of course)!

Huh.

Snap hands out a /48 dynamic v6 addresses. Thats 65,536 /64s.
They are handing out a /56 for static. That's 256 /64s.

Using "only a /56" when describing 4,722,366,482,869,645,213,696 addresses for a home connection doesn't really make sense to me.

Oops, sorry! I got my post wrong. Replace /64 with /48. The recommended IPv6 assignment to a site was a /48, but that seems to have been changed. See http://tools.ietf.org/html/rfc6177.

Evrybody using /48 prefixes means it is easy to change ISPs and just delegate a new prefix. Changing the netmask size causes problems. I currently have a /48 from tunnelbroker.net, and changing to a /56 will mean changing all the suffixes I am currently using as they were done from the old recommendations and have the top byte of the suffix as the subnet number. I will also have to change all my DNS server data to match as well, instead of just using a global replace on the prefix value. And I have run across specialised software that says it only works with /48 blocks - sorry, I can not remember what it was. As smaller assignments become common, hopefully such software will be fixed, but if you need a function provided by such software only, then you are out of luck.

Right yes, this makes more sense. Yes there have been changes, and you'll see more variance among various providers as a result.
Perhaps you might see a /48 more likely handed out on 'business' plans these days or something, if thats a thing.

This is a good general discussion of the issue, for anyone interested:

How on earth are people meant to scrape by with a /56 rather than /48?

Noodles: How on earth are people meant to scrape by with a /56 rather than /48?

Genuinely curious of what sort of network situation except a large home business would struggle with a /56?

If you are a non residential customer i imagine you get allocated a /48 or lower (or just route your own allocation).

Given that you usually get a single static ipv4 ip (that you NAT), and many residential users i imagine only go for a /24 tops if getting a subnet, a /56 of 256 /64s seems like a reasonable equivalent amount.

i suspect noodles was making a bit of a joke there...

Sorry, I forgot to add the sarcasm tag :)

/56 = 4,722,366,482,869,645,500,000 hosts
/48 = 1,208,925,819,614,629,200,000,000 hosts

I always wondered why allocations were so large, surely something like a /112 (65,536 hosts) would do for any home/business.

V6 addresses are used in totally different ways to v4, especially thanks to all the extensions. You don't think of it in terms of unique addresses, but rather in terms of allocatable subnets within that. And yes i realise i mentioned the size of a /56 above, i am being a hypocrite in this case.
Having a number of /64s is useful for several reasons:
