1177350	2011-02-12 02:28:00	If I get an IPv6 fibre internet connection, will I still be able to VPN into my work (IPV4 DSL) and and VPN from work to home through NAT or whatever the ISPs use to bride IPv6 & IPv4?	Greven (91)
1177351	2011-02-12 02:55:00	Is the fibre connection really IPv6-only? You'd be far better off going with dual-stack (i.e. both IPv6 *and* IPv4). That said, you should be able to get at IPv4 hosts via IPv6-only if you have a NAT64 gateway available, but it's not ideal.	Erayd (23)

IPV6 is coming along but much of the inter-connection to IPV4 is a bit crap.	robsonde (120)

Just checked up on the Xbox. It doesn't support IPv6 :( I recommend that you just put IPV6 on the back burner for about 18 months. by that time many move devices will support IPV6 and you will have much more luck getting things working.	robsonde (120)

You may have missed the announcement that the last of the IPV4 addresses had been handed out last week so it is rapidly coming to an end and you will only be able to get IPV6 addresses soon (unless you use your ISP dynamic supplied address).	veldthui (15543)

Any routing between the two protocols (e.g. NAT64) is done as a stopgap measure only, mostly by ISPs and large corporates. It is dual stack...Good - in that case, I strongly suggest that you use it as such, it'll save you a mega headache. ...but Webgauge have told me that routers running DD-WRT & similar have a much better throughput if instead of doing NAT, they pass through public IPv6 addresses to all devices on the LAN.IPv6 doesn't have NAT at all in the classical sense, you can't really do much else :rolleyes:. It's also worth pointing out that if you're using a WebGauge router, they can't count IPv6, and can't route it (no kernel support) - if you want to pass IPv6 traffic through a WebGauge router, you'll need to bridge it directly at the ethernet layer.

IPV6 is a very important move for the internet, but not a "sky is falling" kind of issue. most ISP's will keep using IPV4 and just build a IPV4 -> IPV6 gateway. this will solve 90% of the issues for the next few years. in 5 years time IPV6 will be much more supported and used more. I have said this before and I say it again and I stand by this prediction: there will be no need for IPV6 for a home user in the next two years. there may be a few home users who have IPV6, but they will only by the geeks who are playing with toys. all ISP's will still have IPV4 as the core service.	robsonde (120)

Those figures don't quite add up - one /8 is 16,777,216 addresses, and APNIC burns through a *lot* more addresses than 300,000 in a few months. ...but most ISP's have many IP address that they are not yet using. for example one large ISP in NZ has more than 5,000 IP's that are not assigned yet.Of course - but noting the kind of figures we're talking about, 5,000 addresses is *not* a lot. IPV6 is a very important move for the internet, but not a "sky is falling" kind of issue.Not for us here in NZ, but the sky will start falling in China and on large mobile networks pretty shortly - which then means that end users here in NZ will require IPv6 connectivity to access those hosts. ...most ISP's will keep using IPV4 and just build a IPV4 -> IPV6 gateway.Really? Noting the issues that the reduced MTU will cause, and the lack of consumer hardware than can anchor such a tunnel, I highly doubt that ISPs will use this as their main solution. Dual-stacking makes much more sense, both from a financial and a practical standpoint. ...this will solve 90% of the issues for the next few years.Any chance you could expand on this? 90% isn't enough unfortunately, it's the 10% that kills you. ...there will be no need for IPV6 for a home user in the next two years. there may be a few home users who have IPV6, but they will only by the geeks who are playing with toys.Of course - most home users in NZ won't *need* IPv6 connectivity, but it'll become increasingly more useful to have, especially for those who deal with China et al. ...all ISP's will still have IPV4 as the core service.As a core service - many already have plans to run dual-stack within this timeframe (and some already are). Sticking your head in the sand is all very well, but at some point you need to start preparing for the inevitable, and leaving it until things start breaking isn't exactly a sensible way to address the issue.

Those figures don't quite add up - one /8 is 16,777,216 addresses, and APNIC burns through a *lot* more addresses than 300,000 in a few months. my bad, the numbers I have been given are for /24's. so that makes 300,000 /24's that APNIC have to hand out.... Any chance you could expand on this? 90% isn't enough unfortunately, it's the 10% that kills you. that is just my gut feeling, all of this is a leap from the theory to the practical. in theory everything will be fine, in practice I expect that there are going to be a few problems. connectivity between IPV4 only systems and IPV6 only system is one of the issues that will have to be looked at, not all ISP's are going to make customers upgrade to duel stack. the only other way to make things work is a IPV6 gateway (proxy). I am very keen to see the whole world upgrade to IPV6, and it would be nice if everyone did, but this is the real world, there are going to be a few smaller ISP's who can't/won't upgrade to IPV6. for them a IPV6 proxy will be the quick and easy answer. most ISP's already have a inline proxy even if the customers don't know about it. all they need to do is give it a IPV6 external IP and some DNS magic and they are done...	robsonde (120)
